Disassembly Sequence Planning Methodology for EOL Products Through a Computational Approach

Minimization of adverse environmental effect by generated e-waste day to day became challenging in different sectors of both developed and underdeveloping countries. Promoting 3’Rs policy such as reuse, resale, and remanufacture from the EOL products found as an only possible solution for the encountered challenge. An efficient disassembly sequence plan is needed to perform necessary operations and sorting out the relevant parts from EOL products. In order to achieve this, different existing methods have been studied and observed that subassembly identification is most essential in disassembly sequence planning to formulate an efficient solution. But the involvement of more computational effort in SI-based DSP got less research interest. Part concatenation method in ASG proved for generation in ample amount of subassemblies besides ASP. In this paper, a novel attempt has been made by implementing PCM to perform DSP. The results indicated that the method has tremendous workability not only in DSP but also extendable to PDSP, SDSP, and CDSP. The working of PCM on various classifications in DSP is explained with a case study and described well with suitable illustrations.
