ABSTRACT
<p>Over the past several years, heuristic methods are often used to find optimal solution(s) of disassembly/recycle sequencing problem, for it is a NP-hard combinatorial optimization problem.</p> <p>In the proposed research, first, we present a method: product disassembly sequence planning problem could map onto a problem of searching the optimal tour in the Disassembly Feasibility Information Graph (DFIG).</p> <p>Then a genetic algorithm is proposed to search the optimal solution of disassembly/recycle problem. Optimization objective is the performance of a solution, which is mainly related with three factors: disassembling process, environment impact and disassembly &recycle line. In particular, scheduling disassembly &recycle line is also a NP-hard problem. Therefore, a heuristic genetic operator, combined with disassembly &recycle processes tree, is also presented to schedule the disassembly &recycle line.</p>
