A disassembly planning software system for the optimization of recycling processes

This paper describes the methods and algorithms adopted in a software system for the generation of optimized disassembly plans to be used in recycling of end-of-life goods. Three aspects of the system are particularly emphasized: the integration with CAD; the capability to automatically detect the subassemblies of the product; and the capability to auto matically generate all the feasible disassembly sequences. The selection of the best disassembly plan is made on the basis of the maximum profit achievable from the recycling of components, calculated according to the information contained in a database and concerning the market, the available tools, etc. A meaningful example of application is reported and discussed in detail, analysing the system performance in different situations, e.g. different market conditions, different deterioration of the good, application of different kinds of disassembly operations.
