Disassembly sequence planning for an end-of-life car

In order to prepare the re-use of parts as well as the re-utilization of materials, disassembly of used products is required. For efficient disassembly process, it is very important to choose an optimal disassembly process plan. In this paper, we propose that a methodology generate an optimal disassembly process plan by determining disassembly methods, disassembly depth and disassembly sequence based on the existing assembly information. PLM curve that is used to determine disassembly depth consists of profit value, disassembly cost and disassembly effect. Using assessment criteria, alternative disassembly sequences, whish is generated by MRFD, are evaluated and optimal disassembly sequence is proposed. This methodology is applied to generate the optimal disassembly process plan of door trim as an example.
