Due to ever increasing challenges faced by our global society, circular design and the idea of product-service systems (PSS) isgaining traction within businesses. However, ‘predicting’ the value of a future PSS solution in the early design phases is difficult,since it requires the ability to balance long term potential with short term decisions. Modelling and simulation is believed to beable to support this challenging task. A simulation framework for circular design of PSS is presented. The simulation processenables the comparison between functional and non-functional performances and their life cycle contributions depending on adefined PSS-like business model strategy. Such integrated simulation framework is intended to exploit engineering modelsoutside their specific discipline, enabling cross-functional collaboration and help decision makers understand how a design cancontribute in satisfying customer and stakeholders needs during the lifecycle of a PSS.
