Modeling and Planning for Dual-Objective Selective Disassembly Using and /or Graph and Discrete Artificial Bee Colony
IEEE Transactions on Industrial Informatics(2019)
摘要
Disassembly sequencing is important for remanufacturing and recycling used or discarded products.
AND
/
OR
graphs (AOGs) have been applied to describe practical disassembly problems by using “
AND
” and “
OR
” nodes. An AOG-based disassembly sequence planning problem is an NP-hard combinatorial optimization problem. Heuristic evolution methods can be adopted to handle it. While precedence and “
AND
” relationship issues can be addressed,
OR
(exclusive
OR
) relations are not well addressed by the existing heuristic methods. Thus, an ineffective result may be obtained in practice. A conflict matrix is introduced to cope with the exclusive
OR
relation in an AOG graph. By using it together with precedence and succession matrices in the existing work, this work proposes an effective triple-phase adjustment method to produce feasible disassembly sequences based on an AOG graph. Energy consumption is adopted to evaluate the disassembly efficiency. Its use with the traditional economical criterion leads to a novel dual-objective optimization model such that disassembly profit is maximized and disassembly energy consumption is minimized. An improved artificial bee colony algorithm is developed to effectively generate a set of Pareto solutions for this dual-objective disassembly optimization problem. This methodology is employed to practical disassembly processes of two products to verify its feasibility and effectiveness. The results show that it is capable of rapidly generating satisfactory Pareto results and outperforms a well-known genetic algorithm.
