A proposed multi-objective optimization model for sequence-dependent disassembly line balancing problem

Abstract

The government and public growing concern for waste is how to manage the returned products to realize the resource recycling and reuse. Product recovery operations are utilized to retrieve the desired parts and subassemblies out of the used products. It is important to design and balance disassembly line to optimize the product recovery process. Considering the disassembly precedence relationships and sequence-dependent parts removal time increments, this paper presents a multi-objective sequence-dependent disassembly line balancing problem (SDDLBP) optimization model, taking the number of opened workstations, total disassembly time, idle times of opened workstations, the hazardous components and high-demand parts altogether. The performance of the proposed model is evaluated by benchmark instances, and the computational results indicate the rationality and validity of the proposed model for solving multi-objective SDDLBP.
