Cable harness is an integral part of a modern-day automobile. The design of many mechanical components is based on the cable harness and hence it is important to accurately calculate the space occupied by cable harness. In this thesis, a theoretical model representing n arbitrarily sized cables was used to generate a packing of the cable harness, and the space occupied by them was calculated. The model was used to develop an algorithm that generated a feasible configuration and a container around that packing. The optimisation toolbox in MATLAB was also used to calculate the space and optimise the container size. A customised standalone tool was developed in MATLAB by utilising the established methods, that enables calculation of space occupied by cables at various points of interest along the truck chassis for Scania CV.
