Automated analysis of product disassembly to determine environmental impact
Manufacturers are increasingly being held responsible for the fate of their products once reaching end-of-life. This research uses disassembly time and re-cyclability to gauge the environmental impact of a product upon disposal, where re-cyclability is the amount of mass recovered when parts are removed from an assembly. A graph-based method of representing product assemblies is suggested, which takes component connection methods into account. The result of a disassembly simulation is Pareto sets whose contents represent stages in the disassembly process. These are then used to judge a product's performance during end-of-life, from a re-cyclability perspective, against those of other products.
