    Abstract [en]

    Today more than ever, Computerized Trouble Ticketing System is becoming a booming information technology system that makes the difference between staying in business in a competitive global telecommunication arena.

    This quantitative exploratory survey utilised conveniently selected research subjects to explore computerized trouble ticketing system and its inherent benefits in Vodafone Ghana Plc. Cross section of vital data set collected with the aid of structured questionnaires haven been analyzed using descriptive statistics model.

    The study revealed that, effective and efficient usage of computerized trouble ticketing systems benefit the company in terms of its customer satisfaction, competitive advantage and business intelligence in competitive telecom arena. Nevertheless, the smooth realization of these inherent benefits are constantly challenged by complexity in managing volumes of data generated, intense era of competition, high cost of trouble ticketing system, as well as, rapid technological obsolesce in computerized trouble ticketing applications in telecommunication market.

    The study recommended for the quick and effective adoption of differentiation strategy, cost leadership strategy and customer relationship management, which are customer-centric measures that can build sustainable long-term customer relationship that can create value for the company, as well as, for the customers.

    Urban Public Space: A Case from Developing Country2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Cities in developing world are inadequately equipped with public spaces. The increasing urbanizations trend is attracting more people to come to the cities without having proper sustainable plan for public spaces. However, this social public place holds the important function for urban well-being and collective recognition. This is the place where human can participate as fully fledged social subjects in complex civic life. Unfortunately, in most cases the provision of public space in these cities is always neglected or poorly integrated in planning legislations. So, in many cases community people make their own ways of social interaction that gives public space a new definition. Khulna, one of the divisional cities of Bangladesh, is going through the similar developing country situation. Lack of fund and space restricts development agencies to make new public spaces in this city. On the other hand management and coordination challenges between multilevel planning authorities also making existing public spaces malfunctioned. Sustainably planned, created and managed public spaces are hence urged for the cities of developing world to get livable and healthy urban environment.

    A systematic review of value metrics for PSS design2017In: Procedia CIRP, 2017Conference paper (Refereed)
    Abstract [en]

    The notion of ‘value’ has become pivotal in the PSS domain, with a plethora of ‘indicators’, ‘drivers’ and ‘measurements’ proposed to guide the assessment of PSS concepts across the design process. This paper presents the results of a systematic literature review that maps existing contributions dealing with metrics for PSS value in early design. The findings reveal the lack of a common taxonomy to define what PSS value is, as well as differences in terms of granularity of the applied metrics, which span from very generic to highly case-study specific. This mapping aims at validating a proposed classification framework for such metrics, which balances customer and provider value perspectives in early stage PSS concept assessment activities. Its goal is to raise the cross-functional design team awareness on the multiple value types impacted by early stage design decisions when working with MADM matrixes; hence to highlight opportunities for improvement, recombination and refinement.

    Participatory Design Ideals2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The Swedish academic discipline Informatics has roots in the Scandinavian design approach Participatory Design (PD). PD’s point of departure is to design ICT and the new environment it becomes part of together with the future users driven by the ideal to bring more democracy to the workplace. PD builds further on the Action Research and industrial democracy tradition already starting in the 1960s in Scandinavia, in which the powerful Scandinavian trade unions have a central role. The aim of the unions is to prepare the workers and have influence on the introduction of new technologies that (are expected to) change the work and work environment of the workers. In the 1970s, when more computers emerge in the work place, this leads to the development of PD. Important difference with AR is that the aim of PD is to actually design new ICT and the new environment it becomes part of.

    During the in PD literature much referred to project UTOPIA in the first half of the 1980s, led by project leader and PD pioneer Pelle Ehn, it is discovered that bringing the different expertise of designers/researchers and workers together in design-by-doing processes also result in more appropriate ICT.

     

    With ICT being ubiquitous nowadays, influencing most aspects of our lives, inside and outside the workplace, and another role of trade unions in (Scandinavian) society, a question is how PD should further develop. PD pioneer Morten Kyng (also a UTOPIA designer/researcher) proposes a framework for next PD practices in a discussion paper. The first element he mentions in the framework is ideals; The designer/researcher should as a first step consider what ideals to pursue as a person and for the project, and then to consider how to discuss the goals of the project partners, for which Kyng does no further suggestions how to approach this.

    This design and research thesis has as aim to design and propose some PD processes to come at the beginning of a PD/design project to shared ideals to pursue, based on a better understanding of the political and philosophical background of PD, including design as a discipline in its own right.

     

    For a better understanding of the political and philosophical roots of PD, and design as a discipline in its own right, Pelle Ehns’s early (PD research) work and (PD) influences and supporting theories are explored, next to Kyng’s discussion paper (framework) and reactions from his debate partners on this. Find out is that politics and what ideals to pursue in PD are sensitive and (still) important subjects in PD, and in a broader sense also for design in general one could argue. In relation to this also related disciplines like Computer Ethics, Value Sensitive Design, and more recent formulated ideals for PD and its relation to ethics are explored. As a result a proposal for a redesigned framework for next PD practices as a design artefact is designed, in which the element ideals is most elaborated.

    Before the understanding of design as a discipline in its own right is further explored by exploring a selection of different models and quotes from related (design) literature, on which is reflected also in relation to PD, and which are used as reminders in a design process to come to a proposal for a model that tries to reframe the relation between design, practice and research.

     

    Finally some methods, processes and techniques used in PD, design, AR and related literature that can contribute to design proposals for design processes that enable the design of ideals using a PD approach, are explored. These are used as reminders in design-by-doing processes, in which suggestions for techniques and processes to design ideals together with participants are tried out in real live situations, reflected on and iteratively further developed. Trying to avoid framing as much as possible, (semi-) anonymity and silence seem to be important ingredients in these processes to stimulate the generation of idea(l)s as much as possible free from bias and dominance patterns. An additional design artefact developed in this context is a template for an annotated portfolio used to describe and reflect on the different processes.

    Sustainable Personal Road Transport: The Role of Electric Vehicles2016Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Electric vehicles can play an important role in a future sustainable road transport system and many Swedish politicians would like to see them implemented faster. This is likely desirable to reach the target of a fossil independent vehicle fleet in Sweden by 2030 and a greenhouse gas neutral Swedish society no later than 2050. However, to reach both these targets, and certainly to support the full scope of sustainability, it is important to consider the whole life-cycle of the vehicles and also the interaction between the transport sector and other sectors. So far, there are no plans for transitions towards a sustainable transport system applying a sufficiently wide systems perspective, in Sweden or elsewhere. This implies a great risk for sub-optimizations.

    The overall aim of this work is to elaborate methodological support for development of sustainable personal road transport systems that is informed by a strategic sustainable development perspective.

    The Framework for Strategic Sustainable Development (FSSD) is used as a foundation for the work to ensure a sufficiently wide systems perspective and coordinated collaboration across disciplines and sectors, both in the research and application. Maxwell’s Qualitative Research Design and the Design Research Methodology are used as overall guides for the research approach. Specific research methods and techniques include literature studies, action research seminars, interviews, and measurements of energy use, costs, and noise. Moreover, a case study on the conditions for a breakthrough for vehicles in southeast Sweden has been used as a test and development platform.

    Specific results include a preliminary vision for electrical vehicles in southeast Sweden, framed by the principled sustainability definition of the FSSD, an assessment of the current reality in relation to that vision, and proposed solutions to bridge the gap, organized into a preliminary roadmap. The studies show that electric vehicles have several sustainability advantages even when their whole life-cycle is considered, provided that they are charged with electricity from new renewable sources. Electrical vehicles also imply a low total cost of ownership and could promote new local ‘green jobs’ under certain conditions. Particularly promising results are seen for electric buses in public transport. As a general result, partly based on the experiences from the specific case, a generic community planning process model is proposed and its usefulness for sustainable transport system development is discussed.

    The strategic sustainable development perspective of this thesis broadens the analysis beyond the more common focus on climate change issues and reduces the risk of sub-optimizations in community and transport system development. The generic support for multi-stakeholder collaboration could potentially also promote a more participatory democratic approach to community development, grounded in a scientific foundation. Future research will explore specific decision support systems for sustainable transport development based on the generic planning process model.

    A framework for strategic sustainable development2017In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 140, no Part 1, 17-31 p.Article in journal (Refereed)
    Abstract [en]

    The purpose of this paper is to give a comprehensive and cohesive description of the most recent version of the Framework for Strategic Sustainable Development (FSSD), and also to describe and discuss the overall method for developing the FSSD, elaborate on the general rational for and general benefits of a framework of this type, and Validate benefits of the FSSD through examples of its application. The purpose is also to point to pertinent future work. In preparation of this paper, we have reviewed previous publications and other documents related to the FSSD and reflected on the 25-year learning process between scientists and practitioners. We conclude that the FSSD has proven to aid organizations in thoroughly understanding and putting themselves in context of the global sustainability challenge, and to move themselves strategically towards sustainability, i.e., to stepwise reduce their negative impacts on ecological and social systems at large while strengthening the own organization through capturing of innovation opportunities, including new business models, exploration of new markets and winning of new market shares, and through reduced risks and operation costs. Specifically, we conclude that the FSSD aids more effective management of system boundaries and trade-offs, makes it possible to model and assess sustainable potentials for various materials and practices before investments are made, and offers the possibility for more effective collaboration across disciplines and sectors, regions, value-chains and stakeholder groups. We also conclude that the FSSD makes it possible to prevent damages, even from yet unknown problems, and not the least, to guide selection, development and combination of supplementary methods, tools, and other forms of support, which makes it possible to increase their utility for strategic sustainable development. Finally, we have shown that the FSSD is useful for structuring transdisciplinary academic education and research. Several examples of ongoing FSSD related research, as well as ideas for future work, are given. (C) 2015 Elsevier Ltd. All rights reserved.

    Hantering av fysiska säkerhetsrisker – en kunskapsöversikt2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The competence to manage risks related to health, security, fire and safety is a sought-after skill.This is especially noticeable in both business and public administration job postings for therecruitment process of managers, administrators or coordinators to security departments. At thesame time there is little specialist literature available in Swedish on the subject of risk managementin the context of protecting assets and people from physical security threats. The lack of literatureaffects the study of risk management from a physical and procedural security perspective,particularly at an academic level where this is a relatively new topic. To move forward and expandthe field of knowledge is an important step, not only for the scientific community but also for theindustry. This bachelor thesis attempts to be an initial but significant contribution to a topic thatis likely to grow. By mapping what has already been published on the subject in English as wellas summing up and analyzing the scientific knowledge from similar disciplines the thesis has alsohad an additional goal: to reach out with knowledge to those dealing with risk management inpractice, and thus raising their awareness and developing their professional skills.The purpose of this study is to present the current state of knowledge and at the same time toshow the width and depth of the risk management process. This is done by identifying similaritiesand differences in definitions, process descriptions, problems and best practice of the studied areaswhile at the same time account for any criticism offered against risk management as a concept.The results show that there are more similarities than differences in the risk management processand methods regardless of whether the purpose is to protect people and assets from healthhazards, crime, fire or accidents.The paper has been conducted as a descriptive literature study and a comparative textual analysis.The risk management process has been described with reference to the generic ISO standard(31000:2009, Risk management - Principles and guidelines). Also, ten common risk analysismethods that cover all steps in the risk assessment process have been described. The narrative andrelated analysis follow the same order as the ISO-standard process description.The material has been supplemented and compared with guidelines and scientific papers from threetypes of risks management contexts: (1) health hazards, (2) fire and safety, and (3) security.The paper also provides examples of the inconsistent use of terms and definitions both between andwithin different disciplines involved in risk management. One of the conclusions of the report is thatcreating a unified, universal terminology to be used in the security context probably is impossibleas well as being not necessary. Instead, certain terminological misunderstandings can be avoided byproviding clear definitions and explanations of their meaning in each particular case.

    Migrating Cities: How to redefine the regional development in China2015Independent thesis Advanced level (degree of Master (One Year)), 40 credits / 60 HE creditsStudent thesis
    Abstract [en]

    With the rapid development of the urbanization in China, more and more migrants who are mainly from the relatively poor areas move to big cities in order to obtain the economic benefits. However, rather than living condition of migrants and rural development, people pay more attention to the economic development of the city. Migrants cannot achieve reasonable living condition in the urban context, at the same time, they may lose their land and source of income if they come back hometown although they have devoted themselves to the construction of big cities and economic development of rural areas. I analyze the characters of migrants’ living conditions in the big cities and the transfer of labors in rural areas, claiming that we should consider the situation of migrants scientifically when we are conducting the urban planning and urbanization. To explain the phenomenon of migration intuitively, I choose the Zhejiang village in Beijing and four villages in Henan Province as the example to study and analysis in the following. Firstly, Beijing is the capital of China so that it is the most popular place for migrants to move in. Zhejiang village is the famous historic problem in China and there are a lot of literatures and data collections that can be useful for my thesis. Secondly, Henan Province has the largest population in China and the migration is popular there. After the case study and survey, I analyze the reasons of the problem from different perspective such as government, economic differences, migrants’ education and so on. The paper suggests the solutions to solve the problems from relevant aspects.

    Vad händer med norra Bohusläns skärgårds- och kustområde?: riksintresse för turism och friluftsliv.2015Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Uppsatsens syfte har varit att studera hur hanteringen av riksintresset enligt 4:e kap. 1-2 §§ Miljöbalken och motsvarande tidigare regleringar har fungerat över tid i norra Bohuslän, genom att undersöka den faktiska bebyggelseutvecklingen 1976- 2013. Syftet är även att undersöka hur kommunala politiker och tjänstemän samt Länsstyrelsen ser på denna utvecklig och inför framtiden. Detta för att få en indikation om hur området skulle kunna komma vara exploaterat i framtiden. Syftet har besvarats genom följande frågeställningar:

    Hur har bebyggelseutvecklingen skett i kustlandskapet Norra Bohuslän 1976-2013?Hur ser kommunala politiker och tjänstemän samt Länsstyrelsen på denna utveckling?Hur ser kommunala politiker och tjänstemän samt Länsstyrelsen på lagbestämmelserna,4 kap 1-2 § MB, inför framtiden?

    Utgångpunkterna som denna uppsats baseras på är olika förhållningssätt som kunnat urskiljas i den litteratur som studerats.

    Undersökningen i uppsatsen har byggts på två innehållsanalyser, en kvantitativ som baserats dels på kartmaterial från 1976 och 2013 och dels en kvalitativ baserat på intervjuer med utvalda kommunala tjänstemän och politiker samt från Länsstyrelsen.

    I den kvantitativa innehållsanalysen har hela norra Bohusläns kust- och skärgårdsområde omfattandes av ca 60 kartblad av ekonomiska kartan från 1976-1977 studerats och jämförts med fastighetskartan från 2013 för att skapa en bild av hur bebyggelseutvecklingen skett. Resultatet har presenterats generellt utifrån ett helhetsperspektiv för hela kustområdet. I den kvalitativa innehållsanalysen har totalt tio personer intervjuats som antingen i yrket verksamma med fysisk planering inom kustområdet eller har en viktig roll vid beslut kring dem.

    I resultaten av den kvantitativa analysen framkom bl.a. att förhållandevis stor andel av den bebyggelse som tillkommit 1976-2013 har tillkommit på landsbygden, inom ca 1 km från strand- och kustlinje och består i majoritet av bebyggelse för boende. Många av dessa områden består av 4-10 hus, men de färre större områdena med mer än 10 hus, tar ungefär lika mycket mark i anspråk. Av de större områdena som omfattas av bostadsbebyggelsen, består endast ett område i majoritet av helårboende – andelen delårsboende är till stor del övervägande inom kustområdet. Denna huvudsakliga lokalisering nära kust- och strandlinje och på landsbygden stämmer inte med de förespråkande förhållningssätt som kunnat urskiljas. Även om en mindre åtskillnad kan sägas göras idag mellan helår- och delårsboende så påverkar detta kommunernas bostadsplanering, där endast ett område med majoritet helårsboende utgör för liten grund för att slutsatser ska kunna kopplas till förhållande till strand- och kustlinjen. Att mer än hälften av områdena med bebyggelsen för boende har tillkommit i form av mindre omfattande ingrepp stämmer överens med det förhållningssätt som kunnat urskiljas. En förhållandevis liten andel av den bebyggelse som tillkommit på landsbygden är på campingar, tar förhållandevis liten markyta i anspråk, men har ofta tillkommit i attraktiva strandnära lägen som generellt anses ha stort värde för friluftslivet, vilket kan ses som förenligt utifrån det förhållningssätt som kunnat urskiljas, under förutsättning att bebyggelsen används för uthyrning och inte privatiseras. Sammantaget är detta en utveckling inom kustlandskapet som utifrån de förhållningssätt som kunnat urskiljas, en utveckling som kan ses som tveksam, men att kommunerna gör avvägningar mellan olika intressen som enligt planparadigmet är förenligt med intentionerna för riksintressebestämmelserna.

    I resultaten av den kvalitativa analysen framkom bl.a. att kommunala tjänstemän och politiker samt Länsstyrelsen har svårt att bedöma hur utvecklingen skett inom kustlandskapet på landsbygden (utifrån kartstudierna) och hur exploateringen har påverkat helheten och att de uppfattar nuvarande lagbestämmelser (4 kap. 1-2 §§) som vaga, svaga och svårtolkade. Det framkom även att bestämmelserna uppfattas som viktiga men behöver ses över, att förståelsen kring ämnet behöver öka och rutiner ses över.

    Using social sustainability principles to analyse activities of the extraction lifecycle phase: Learnings from designing support for concept selection2017In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 140, no 1, 267-276 p.Article in journal (Refereed)
    Abstract [en]

    Analysing product concepts with respect to social sustainability is a contemporary challenge for which there is little support available for product developers. Our aim was to build on previous work to support product developers in a case company with this challenge. We designed a first prototype of support for product developers to use a previously developed definition when analysing the extraction lifecycle activities associated with their product concepts. The prototype instructs users to model the location of the extraction activities and then use existing databases and indicators to analyse the social sustainability performance of each location. The databases and indicators were selected according to their relevance to scientific principles for social sustainability. We then performed initial evaluation of the support, through which we learnt that the approach may make it possible for product developers to analyse extraction activities, but the level of accuracy of analysis that is possible is not good enough for comparing the concepts in the case study decision. We discuss the implications of these challenges and suggest that it may be better to re-design our approach in order to provide learningful support for product developers or support for other decision-making in the company.

    Automated file extraction in a cloud environment for forensic analysis2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The possibility to use the snapshot functionality of OpenStack as a method of securing evidence has been examined in this paper. In addition, the possibility of extracting evidence automatically using an existing operation tool has been investigated. The usability of snapshots in a forensic investigation was examined by conducting a series of tests on both snapshots and physical disk images. The results of the tests were then compared to evaluate the usefulness of the snapshot. Automatic extraction of evidence was investigated by implementing a solution using Ansible and evaluating the algorithm based on the existing standard ISO 27037. It was concluded that the snapshots created by OpenStack behaves similar enough to disks to be useful in a forensic investigation. The algorithm proposed to extract evidence automatically seems to not breach the standard.

    Sustainability integration in a technology readiness assessment framework2017In: Proceedings of the International Conference on Engineering Design, ICED / [ed] Van der Loos M.,Salustri F.,Oehmen J.,Fadel G.,Kokkolaras M.,Maier A.M.,Skec S.,Kim H., The Design Society, 2017, Vol. 5, no DS87-5, 229-238 p., DS87-5Conference paper (Refereed)
    Abstract [en]

    In this paper, an approach to systematically include sustainability into the Technology Readiness Levels (TRL) is proposed. The aim is to answer the question "how can sustainability provide systematic guidance in technology development and early product development?". Results from a case study illustrate that the suggested approach can support i) the inclusion of sustainability into the early design stages, when only limited data and information is available; ii) the enhancement of the comprehensiveness of sustainability and ease of use in the day-to-day engineering working environment; and iii) simplified sustainability assessments without being too simplistic and/or reducing the sustainability scope. The proposed approach is being co-developed in collaboration with a case company, and tests on an actual technology development project are planned. The next steps are related to the application of the proposed approach in other companies to test its robustness and enhance its generalization for application in diverse contexts.

    Active learning via Transduction in Regression Forests2015Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Context. The amount of training data required to build accurate modelsis a common problem in machine learning. Active learning is a techniquethat tries to reduce the amount of required training data by making activechoices of which training data holds the greatest value.Objectives. This thesis aims to design, implement and evaluate the Ran-dom Forests algorithm combined with active learning that is suitable forpredictive tasks with real-value data outcomes where the amount of train-ing data is small. machine learning algorithms traditionally requires largeamounts of training data to create a general model, and training data is inmany cases sparse and expensive or difficult to create.Methods.The research methods used for this thesis is implementation andscientific experiment. An approach to active learning was implementedbased on previous work for classification type problems. The approachuses the Mahalanobis distance to perform active learning via transduction.Evaluation was done using several data sets were the decrease in predictionerror was measured over several iterations. The results of the evaluationwas then analyzed using nonparametric statistical testing.Results. The statistical analysis of the evaluation results failed to detect adifference between our approach and a non active learning approach, eventhough the proposed algorithm showed irregular performance. The evalu-ation of our tree-based traversal method, and the evaluation of the Maha-lanobis distance for transduction both showed that these methods performedbetter than Euclidean distance and complete graph traversal.Conclusions. We conclude that the proposed solution did not decreasethe amount of required training data on a significant level. However, theapproach has potential and future work could lead to a working active learn-ing solution. Further work is needed on key areas of the implementation,such as the choice of instances for active learning through transduction un-certainty as well as choice of method for going from transduction model toinduction model.

    A process for designing lean-and sustainable production2017In: Proceedings of the International Conference on Engineering Design, ICED, The Design Society, 2017, no DS87-1, 51-60 p., DS87-1Conference paper (Refereed)
    Abstract [en]

    Today's trends such as globalization, increased customer demands, and increased sustainability challenges have caused a paradigm shift, where the importance of designing lean-and sustainable modern manufacturing systems is realized by many companies. This study proposes a process of action steps using Value Stream Mapping method integrated with sustainability life cycle analysis and sustainability compliance index to assist in designing lean-and sustainable production systems. The developed process was validated through a case study to test the adopted tools and how they can capture and improve the lean-and sustainability levels. The current sustainability and lean levels were explored first, followed by analyzing and developing the future improved state. A roadmap of about 40 actions was suggested to the case company distributed on a one year time plan. The key contribution of this study is an applicable and generic process of action steps including several adopted tools from the leanand sustainable product development fields to help manufacturing companies in creating roadmaps for more lean-and sustainable production systems.

    Product-Service Systems for Functional Offering of Automotive Fixtures: Using Design Automation as Enabler2017In: Procedia CIRP: 9th CIRP Conference on Industrial Product/Service-Systems (IPSS), Copenhagen, Elsevier, 2017, Vol. 64, 411-416 p.Conference paper (Refereed)
    Abstract [en]

    In production of automotive components, control-measuring is an important activity to assure that geometries meet expected tolerances. This is done via randomly taking parts out of production for control-measuring in a fixture. This fixture is both a tedious and repetitive product to design and configure. The aim of this paper is therefore to present an approach to adopt a design automation strategy towards supporting the configuration of fixtures and to discuss opportunities for moving towards a Product-Service System-paradigm in this domain. This paper reports on a development of a design automation demonstrator to configure fixtures for control-measuring. The demonstrator has been developed in a commercial CAD-environment and will be deployed through a web-based interface. The paper concludes with a discussion on PSS-opportunities and how to drive this with a Knowledge-Based Engineering-modelling approach.

    Maturity of models in a multi-model decision support system2017In: Proceedings of the International Conference on Engineering Design, ICED / [ed] Salustri F.,Skec S.,Maier A.M.,Kim H.,Kokkolaras M.,Oehmen J.,Fadel G.,Van der Loos M., The Design Society, 2017, Vol. 6, 237-246 p., DS87-6Conference paper (Refereed)
    Abstract [en]

    To reduce uncertainty in decisions, engineers experiment with models, such as, exploring what-if scenarios, and thus increase knowledge. Still, because modelling is an idealisation of reality, there is often substantial uncertainty involved, and this decision makers less confident to lean onto models alone when making decisions. The aim of this paper is to conceptualize a design support for improving confidence and validity in models, by communicating uncertainties from modelling and simulation to relevant stakeholders. The paper reports on empirical data from a research profile workshop. The findings illustrate the importance of communicating uncertainties from models between relevant stakeholders in order to drive action. The paper then presents an approach to visualize model maturity levels as well as impact levels in relation to one or several aggregated models. With this approach, focus can move to discuss the knowledge about the knowledge that is created from modelling, and to facilitate discussions on a meta-level about the modelling and simulation. This is exemplified by a test scenario where a multi-disciplinary modelling and simulation of an asphalt roller is presented.

    Business model innovation to explore data analytics value; A case study of Caterpillar and Ericsson.2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of the thesis is to identify a roadmap for well-established companies towards business model innovation to explore data analytics value. The business model innovation currently taking place at Caterpillar and Ericsson in order to explore data analytics value is presented to answer the question: “How do established companies explore data analytics to innovate their business models?” Initially, the problem discussion, formulation and purpose are given. Then, the relevant theory is presented covering the importance of data analytics, IT infrastructure challenges due to the increased volume of data created, data analytics methods currently being used, smart connected products and the Internet of Things. The meaning of business model innovation is given, followed by a well-structured business model process which includes the business model canvas for representation purposes. The business areas affected by data analytics value and the barriers of business model innovation are given as well. After that, the theory addressing business model innovation to explore data analytics value is presented and the main industries which are currently on this journey along with the required initial steps and the business models that can come out of this process are identified. The challenges and risks if the option of not following this route is chosen are also shown. The method section follows to explain the case study design, data collection method and way of analysis. The results cover all the information gathered from numerous sources including on-line available information, papers, interviews, videos, end of year reviews and most importantly current Caterpillar and Ericsson mid-level management employee answers to a questionnaire created and distributed by the authors. The business model canvas tool is used to aid the reader understanding Caterpillar’s and Ericsson’s business model innovation. Each company’s business model is given before and after data analytics adoption. Finally, the analysis of the results and the link with the theory is given in order to answer the thesis question.

    Pay per screen: developing Result-oriented PSS in Small and Medium-Sized Enterprises: A case study at a mercury recycling equipment manufacturer2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Today’s companies are struggling with the competitive environment driven by resource scarcity, technical progress and market demand for increased value and flexibility. For these reasons companies are shifting their focus from selling products to selling need fulfillment. The result-oriented product-service (PSS) is a PSS type that provides value mainly through delivery of services with the premise of the producer taking responsibility over the entire product life cycle. It is highlighted in the literature as a business strategy to generate a high profit and stable the revenue. Despite the new market opportunities related to the provision of PSS, it inherently comes with complexity linked to the extended responsibility. More importantly, very little is mentioned in the PSS literature regarding real case PSS development and how service-oriented PSS contracting impacts Small and Medium-sized Enterprises (SMEs).

    The objective of this thesis is to examine how result-oriented PSS can create new opportunities for SMEs. It is targeting to explore this topic from a cost and value creation perspective for both the company and customer. To achieve the objective a main research question is stated which answer is given by answering the two sub questions as below.

    How can a result-oriented product-service system be implemented in small and medium-sized enterprises?

    1. What result-oriented PSS solution can be designed for the recycling equipment industry to increase the value for both the manufacturer and the customer?

    2. What are the financial implications of a result-oriented PSS?

    To explore answers for the research questions, a case study inquiry is carried out on MRT (Mercury Recovery Technology) System International AB. It is a small international recycling equipment manufacturer in Karlskrona. A PSS development process resulting in a new concept referred to as “Pay per screen” is developed.

    The development and analysis of the result-oriented PSS shows that it is more profitable for the company to offer the proposed Pay per screen concept compared to the current product- oriented business. Even the customer has proven to be profitable while providing several advantages such as avoid being responsible for initial investment and maintenance costs.

    Effect of Filtering Function on User Search Cost and How to Enable the Creation of this Function2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    It has been noticed that one of the main challenges for e-commerce sites is providing the users with an efficient search function. It has also been noticed that the search function is one of the things the user is valuing the most when evaluating an e-commerce. The information technology enables the possibility to consume almost anything one could wish for. The challenge is in how to find this specific item. It is hence of interest to examine how to improve the search tool and what effect the updated search tool results in.

    The objective of this research is twofold. The objective motivated by economic factors is to examine how a user’s ability to find relevant items is affected by being able to refine a search result by selecting relevant attribute values. The other objective has a more technical character and is to examine how the rule based method performs in terms of extracting attribute values for enable the creation of the filtering function.

    The examinations for this research is conducted at a Swedish online auction company that due to the structure of its e-catalogue provides a suitable setup for the examinations. Because of the examinations being conducted in the environment of the auction company’s system this limits the result to only being representative for data with the same characteristics as the auction company’s.

    For answering the questions stated in the objective two methods are applied. One for examining the economic part and one for examining the technical part. The economic question is answered after analysing the result of an A/B-test conducted at the auction company. For answering the technical examination an information extraction technique is evaluated.

    The result of the economical examination is that a significant increase in conversion rate can be concluded for the system version with filtering enabled. The result of the technical examination shows that the rule based method can be used for information extraction in some cases. However, the obtained accuracy will be affected by the characteristics of the data the information extraction is performed on.

    Perception of Colors in Games as it Applies to Good and Evil2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Context. Color can be used to convey allot of information but in particularly when it comes to tellingwho is good and who is evil. The most common color to use when displaying good and evil is blue forgood and red for evil.

    Objectives. This study will take a look at what colors people automatically associated with good andevil respectively.

    Methods. The two methods that are used in this paper is a survey in the form of a questionnaire andthe second method is a statistical hypothesis testing that was done on the data collected in the survey.The statistical hypothesis testing was done in the form of a chi-square test. From the chi-square testyou get a chi-square value and a p-value.

    Results. The result of the survey was that most participants thought of green, white and blue as goodcolors, while black and red where thought of as evil. The statistical hypothesis testing revealed thatthere where a significant statistical difference when comparing two colors in all but two cases. Thosecases where white vs. blue and orange vs. purple.

    Conclusions. The conclusions that can be drawn are that there is a significant statistical differencebetween how a color is perceived as good or evil. The perceived convention for what a good charactershould have, as a color is that it should be green and the perceived convention for an evil character isthat it should be either red or black.

    Evaluating Immersion in Video Games Through Graphical User Interfaces2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Context. The feeling of immersion in a video game is something most game developers try to achieve. Immersion makes the player feeling like they are a part of the game they are playing, and causes them to lose track of time and space. Immersion can be achieved in many ways, one of them being through different kinds of Graphical User Interfaces. An integrated interface might help players to get more immersed.

    Objectives. The objective of this thesis is to find out whether an integrated or "diegetic" interface improves the feeling of immersion in players.To fullfil this objective, a prototype must be made and then tested using participants who then can answer questions about their level of immersion.

    Methods. The prototype was built using Unity, a free game engine. The participants of the study played two different levels with two different interfaces and then answered a number of questions in a questionnaire. The questions were then analysed using the students t-test.

    Results. The results of the study showed there were no difference in terms of immersion in the two different interfaces.

    Conclusions. These results suggest there is no improvement of immersion when using a diegetic interface, compared to using a non diegetic one.

    Rediscovering Lean Paradigm to Derive Innovation in the Engineering Services Sector2015Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background - Lean paradigm has been successfully employed in the manufacturing sector in past decades, however in the engineering services sector its application has unfortunately not received the same attention both from academia and industry.

     

    Problem Discussion – The negligence of Lean in the engineering services sector rendered this sector deprived from Lean’s proven benefits in the manufacturing sector. The reason for this negligence can be traced back to the fact that Lean’s implementation is not a straightforward task and additionally its direct translation from the manufacturing sector into the engineering services sector may impede innovative capabilities of the engineering services sector that are crucial for its sustainable growth.

     

    Problem Formulation - In addressing the aforementioned issues, this thesis investigates the following key research question: “Whether and how Lean Innovation can be implemented in the engineering services sector?”

     

    Purpose - This work explores and employs different modern theoretical concepts from literature to promote Lean Innovation in the engineering services sector by first developing a theoretical framework in terms of nine propositions and then examining them through a qualitative empirical research.

     

    Methodology - The qualitative empirical research is conducted by first gathering empirical data through expert interviews and then analysing it employing the directed content analysis technique in order to examine the nine propositions promoting Lean Innovation. 

     

    Findings - This study concludes that Lean Innovation in the engineering services sector is achievable by employing modern theoretical concepts like open innovation, the systems approach to problem solving and transformational leadership in a thoughtful and planned manner.

     

    Limitations - The lack of depth of the theoretical as well as empirical research focus in terms of the sample size and quality stemming from the challenge of finding enough experts with versatile knowledge in the thesis’ timeframe can be considered as limitations on the quality of this research.

    Prisoners' dilemma misleads business and policy making2017In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 140, no Part 1, 10-16 p.Article in journal (Refereed)
    Abstract [en]

    The prisoners' dilemma is a game-theoretical construct about trust. It can be seen as a simple version of the 'tragedy of the commons', which is often used in the sustainability context as a metaphor for the tension between responsibility for common resources and the perceived self-benefit to individual organizations, regions or nations who neglect such responsibility in the short term. However, other game theory and developments in sustainability science imply that the prisoners' dilemma mind-set is delusive and misleading for both business and policy making. It helps obscure an even more important aspect of proactive leadership for sustainability: the potential self-benefit of understanding the dynamics of major system change better than one's 'competitors'. The UN 1972,1992; and 2012 summits on sustainability, as well as the many summits on climate change, have been valuable milestones for influencing societal leadership at all levels. However, due to the prisoners' dilemma mind-set, they have also indirectly helped reinforce the idea that sustainability only pays off if the costs of achieving it are shared by all. That, in turn, has encouraged decision makers to believe that 'our organization's, region's or nation's sustainability activity must rely on policy making changing the rules of the game for everybody'. This focus on policy making as the only or main facilitator of sustainability efforts delays the needed transition of global society. By considering game theory such as tit-for-tat and modern systems science for sustainability, this paper illuminates major shortcomings of the prisoners' dilemma in the context of sustainability, and attempts to provide a more fruitful mind-set that can be motivated both theoretically and empirically. It is argued that a large part of the self-benefit of proactivity for sustainability is direct, i.e. independent of other actors' actions for the common good. In addition, it is argued that the self-benefit to businesses can be further increased through voluntary collaboration with other businesses to promote the common good, as well as through collaboration between proactive businesses and policy makers. Currently, none of this is intelligently and operationally part of mainstream leadership and public discourse on sustainability. The clarifications provided in this paper can lead to a much needed shift in mind-set among many leaders, not least political leaders, many of which seem to be trapped in simplistic prisoners' dilemma thinking and who act accordingly.

    Cykelplanering: En komparativ fallstudie av Stockholm, Göteborg och Malmö2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I denna uppsats har det utretts hur Stockholm, Göteborg och Malmö har betonat cyklism och tagit fram riktlinjer för framtida utveckling. För att möjliggöra en utvärdering av deras arbeten sattes i forsknings- och kunskapsöversikten upp riktlinjer som berör cykelns fördelar, vad som påverkar trafikvalet samt cykeln ur ett planeringsperspektiv där det bland annat utreds hur internationellt framgångsrika cykelstäder förhåller sig till cyklism. Med översikten som grund blev det därmed möjligt att analysera hur väl och på vilket sätt de tre svenska städerna planerar för cyklar. Examensarbetet har bedrivits som en flerfallsstudie där de undersökta fallen har analyserats och satts i relation till varandra för att därmed möjliggöra en identifiering av likheter och skillnader. Den applicerade metoden har varit innehållsanalys, empirin har därmed djupgranskas.I fallstudien identifierades att alla städerna planerar för en ökad cykeltrafik med flera av de strategier som applicerats i cykelframgångsrika länder. Malmö som har en längre cykeltradition har kommit längre i arbetet än Stockholm och Göteborg. Alla städerna har dock som mål att en större andel av resorna i framtiden ska ske med cykel. För att uppnå detta mål ska både hårda och mjuka åtgärder vidtas i form av fysisk planering samt beteendeförändringar. Inte förrän detta sker kommer resmönstren att förändras.

    Challenges for integrating sustainability in risk management-current state of research2017In: Proceedings of the International Conference on Engineering Design, ICED, The Design Society, 2017, no DS87-2, 327-336 p., DS87-2Conference paper (Refereed)
    Abstract [en]

    Numerous examples have shown how environmental and social issues can affect companies to an existential level. In fact, today's most urgent business risks, e.g. brand value, legislative change, litigation, and supply chain disruptions, are directly linked to sustainability issues. These risks need to be systematically identified and strategically managed on both strategic company-and operational product development level in order for a company to be long-term competitive. Based on literature review and interviews at case companies, this paper investigates the current state for integrating a strategic sustainability perspective in risk management processes and related support tools. Results show that sustainability risks are not consciously identified and managed at the companies. Research is at an early stage and few frameworks and tools exist. Based on the findings, the study identifies and provides a comprehensive analysis of challenges for sustainability integration, which work as a foundation for future research. Finally, key steps to advance understanding and methods in sustainability risk management are suggested.

    "Hur går det med tillgänglighetsanpassningen, egentligen?"2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    I Sverige finns det lagar och föreskrifter som syftar till att förbättra den fysiska tillgängligheten så att funktionsnedsatta ska kunna tillgodose sig samhällets utbud och service på lika villkor som personer utan funktionsnedsättningar. Men det finns även undantagsregler och intressekonflikter som gör att befintliga miljöer inte tillgänglighets anpassas, vilket påverkar möjligheten för funktionsnedsatta att ta del av samhället. I det studerade fallet visar det sig att en vanlig avvägning  görs mellan att bevara kulturhistoriskt intressanta byggnader och att uppfylla kraven på tillgänglighet. Det studerade fallet ligger i en stad som finns med på UNESCOs världsarvslista, vilket kan vara en anledning till att ovan nämnda avvägning är vanligt förekommande.

    Vid en utvärdering av kommunernas tillämpning av föreskriften lätt avhjälpta hinder, vars syfte är att retroaktivt åtgärda bristande tillgänglighet, fann länsstyrelserna att över hälften av kommunerna har svårigheter att praktisera föreskriften på grund av resurs- och tidsbrist (Boverket, 2012). Fallet som studerats i den här uppsatsen är inget undantag, lätt avhjälpta hinder tillämpas vid kommunalägda, publika fastigheter men i nuläget har kommunen inte resurser till egeninitierade inventering av privatägda, publika fastigheter. Det här tyder på att lätt avhjälpta hinder är en svag föreskrift i praktiken och att den inte fungerar som den var tänkt. Den uteblivna tillsynen av HIN3 syns i det studerade fallet, som utgörs av en shoppinggata, där flertalet hinder som kan klassas som lätt avhjälpta finns kvar och bidrar till att funktionsnedsatta inte kan ta del av all service och utbud längs shoppinggatan.

    Investigating user participation in a participatory design inspired system development process: Insights and outcomes from a study in law enforcement2015Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In an environment of increased demand and competition, organisations are under pressure to provide better and more efficient services. With cuts to funding, public organisations specifically need to redevelop and innovate business processes and Information Technology plays an important part in the process. In order to understand an IT system’s role in an organisation, it has been indicated that it is key for new system developments to consider individuals and human factors, organisational factors and society. Based on studies on the success and acceptance of innovative IT systems, it has now been widely accepted that active participation and involvement of users is essential during system development and deployment. The means of participation that lead to success in a large system development process are however not well understood.In the first paper, we present a theoretical outline of a participatory and socio-technical system development process and describe how we empirically investigated the emergent processes of user participation during a case study that puts this development process in practice. An analytical framework has been deployed to gain a greater understanding of how exactly user participation is embedded in project conditions and participants’ relational structure, and what their consequences are for the project. For the investigated project, genuine participation in different forms was identified to be an important factor for project success with socio-technical design methods strongly supporting user participation during initial and later project stages. We further show how the limited options in facilitating user participation during the more technical phases and the sensitivity of the participants’ relational structure shows the need for more research of how, when and where socio-technical design can be integrated with system development processes in order to guarantee project success.In a second paper, we present outcomes of the case study’s design project phase for the intelligence analyst user group and a vision of a criminal network analysis system. This vision is the result of successful user participation and involvement and is seen as a contribution to further research in law enforcement and criminal network analysis.

    The integration of Design Thinking and Strategic Sustainable Development2017In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 140, no Part 1, 277-287 p.Article in journal (Refereed)
    Abstract [en]

    Human activities are now so pervasive and profound that they are altering the stability of the earth in ways that threaten the very life support system upon which humanity depends. The field of design has contributed to the creation of such complex socio-ecological problems, but it is also adapting as a source for solutions. Design Thinking (DT) was identified as a possible approach that could help create such solutions, and contribute to Strategic Sustainable Development (SSD). The purpose of the research was to examine potential contributors and hindrances of the DT process with regards to SSD, and create a prototype of an integrated process that could help achieve more strategic and sustainable outcomes. Using the Framework for Strategic Sustainable Development (FSSD) as a lens to examine and inform the above, combined with interviews, Action Research and expert feedback, an integrated process was created. It was indicated by participants of the Action Research and by experts that the proposed prototype could help reach strategic and sustainable outcomes, and that further refinement should be pursued. Consequently, a third and final prototype, suggesting a possible Sustainable Design Thinking (SDT) process, was developed. (C) 2015 Elsevier Ltd. All rights reserved.

    Miljö och vatten i fysisk planering: Detaljplanering av Norra Älvstranden i Göteborg2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Många kustnära svenska städer riskerar att drabbas av framtida klimatförändringar, men framförallt stigande havsnivåer, något som ska beaktas och tas hänsyn till i den fysiska planeringen. Men hur? Parallellt med detta pågår stadsomvandlingar, med bland annat nybyggnation i kust- och vattennära områden, för att skapa en attraktiv kommun där folk vill bosätta sig och bo kvar. Den fysiska planeringen präglas , å andra sidan, av en osäkerhet kring hur anpassning till ett förändrat klimat, och särskilt stigande havsnivåer, ska gå till fastän det på den lokala nivån finns medvetenhet om detta. Denna uppsats syftar till att öka kunskapen kring hur klimatfrågor, i synnerhet risker med stigande havsnivåer, hanteras i den fysiska planeringen, genom att undersöka hur detta har behandlats i detaljplanering av tre planområden i Norra Älvstranden i Göteborg.

    För att undersöka syftet har en fallstudie gjorts över tre planområden i Norra Älvstranden, med en kvalitativ dokumentstudie som metod. Detaljplan, med tillhörande plankarta och planbeskrivning för respektive planområde, har ingått i fallstudien. Vidare har Plan- och bygglagen, Boverket och Länsstyrelsen studerats i enighet med uppsatsens syfte. Dessa har undersökts enligt följande analysfrågor som lyder: Hur hanterar lagar och regler samt riktlinjer på nationell nivå klimatfrågor i den fysiska planeringen, mer specifikt i detaljplanering? Var och i vilken utsträckning behandlar detaljplanerna klimatfrågor, framförallt stigande havsnivåer? Hur beskriver detaljplanerna synen på vattnet? Hur hanteras bebyggelsen när det gäller: a) lägsta golvnivå för färdigt golv? b) avstånd till vattnet?

    Diskussionen i uppsatsen görs utifrån teoretiska utgångspunkter som har sin grund i hur den fysiska planeringen hanterar risker med klimatfrågor i dagens samhälle med den ökade globaliseringen och den tekniska utvecklingen, också kallad för ett risksamhälle. Begrepp som robusthet, ett robust samhälle, experternas roll och expertkunskap diskuteras.

    Att dagens klimatförändringar är orsakade av mänskliga aktiviteter är något många forskare diskuterar idag. Det innebär att vi ska möta dess konsekvenser, inte minst inom den fysiska planeringen. Risker med stigande havsnivåer är något som de flesta av kustnära svenska städer möts av redan idag. Norra Älvstranden i Göteborg ligger vid Göta Älv och dessutom i en låglänt terräng. Området, som tidigare har varit ett hamnområde, har successivt omvandlats till ett attraktivt bostadsområde med blandade aktiviteter. Av de granskade detaljplanerna går det att se en medvetenhet om klimatriskerna i detaljplaneringen. Planerna föreslår åtgärder för att anpassa bebyggelsen inför kommande klimatförändringar, exempelvis höjs den lägsta grundläggningsnivån. Å andra sidan går det läsa hur synen på vatten kvarblir som ett viktigt element i planeringen. Sammanfattningsvis kan det konstateras att det finns en ganska oföränderlig syn på hur klimatfrågorna i detaljplaneringen ska behandlas.
