A Disassembly Process Planning Algorithm for End-of-Life Products Recovery and Environmentally Conscious Disposal
Disassembly process planning is an act of preparing detailed operation instructions for disassembling an end-of-life product to recover or dispose its constituent parts or subassemblies. The main decisions are: (a) disassembly level; (b) disassembly sequence; and (c) end-of-life options such as reuse, remanufacturing, recycling, incineration, landfill, etc. This paper deals with the three decision variables simultaneously in the parallel disassembly environment for the objective of maximizing the profit. Unlike previous research studies, we consider practical constraints, i.e., reuse probability and environmental impacts of parts or subassemblies, sequence-dependent setup costs, regulation on recovery rate, and incineration capacity. To represent and solve the problem, we develop an extended AND/OR graph, and then suggest a two-phase algorithm. To show the effectiveness of the proposed algorithm suggested in this paper, a case study has been carried out on an automatic pencil. Also, additional tests on other general product structures are also reported. The test results show that the algorithm suggested in this study good quality solutions within a reasonable amount of computation time for the test instances.
