Research on recycling economy oriented product disassembly sequence planning approach

Under the background of recycling economy strategy, rising environmental costs become serious hazards for the industrial enterprise. To avoid these hazards special activities have to be adopted during the product design phase. Disassembly plays a key role in recycling of materials and components for protecting our environment. In this paper, to realize automated and intelligence of product disassembly sequence planning, a feasibility graph is utilized to represent the abstracted product disassembly sequence mathematical model. Then an improved max-min ant system based on the strategy of sorting elite ants was proposed to find optimal disassembly sequence for given product. Finally, the simulation test for proposed algorithm and a prototype system that supports product disassembly design is developed.
