A Multi-objective Salp Swarm Algorithm for Multi-product Two-sided Disassembly Line Balancing Problem with Special Workers

The escalating volume of discarded large-scale electronic products has triggered significant attention within the research community toward the TDLBP (Two-sided Disassembly Line Balancing Problem. In response, this study presents a biobjective optimization problem for TDLBP, incorporating the considerations of hiring special WGB (Workers with Government Benefits) workers. The objectives are two-fold: one is to maximize disassembly profit, and the other is to concurrently enhance the WGB index. The resulting problem is named a Bi-objective Multi-product Two-sided Disassembly-line-balancingproblem considering Workers-with-government-benefits. MSSA (Multi-objective Salp Swarm Algorithm) is proposed to tackle the problem. The effectiveness of the proposed algorithm is validated through comparison with NSGA-III and MOEA/DCRA.
