To support design tasks of assembly processes of a wire harness, automotive parts suppliers developed CAD/CAM-based systems. However, even if these methods are used, engineers still need to look for efficient assembly processes by trial and error. In order to design efficient assembly processes without expertise of veteran engineers and trial and error, this paper proposes a new method to optimize assembly processes of a wire harness. The process in which a worker tapes routed cables is most important and hardest among the sequence of assembly processes and the difficulty of taping process depends largely on jigs layout on a workbench and taping route. Therefore, in the proposed method, jigs layout and taping route are modeled and optimized by using genetic algorithm. Working time of taping process derived from jigs layout and taping route is used as fitness function of GA. In the case study, to demonstrate the proposed method, design of assembly processes of the automobile wire harness installed in a cer... |
