Salp Swarm Algorithm for Multi-product Parallel Disassembly Line Balancing Problem Considering Disabled Workers

Proper disassembly operation can help increase the recovery of industrial valuable supplies and end-of-life products. To solve a disassembly line balancing problem, this work focuses on a parallel layout and proposes an intelligent optimization method to maximize disassembly profits. It first formulates a parallel multi-product disassembly line balancing problem model by taking disabled workers into account. It then designs a salp swarm algorithm with innovative encoding and decoding processes. This work finally compares the proposed algorithm with a generic algorithm. Experimental results show that the newly proposed model and algorithm can well deal with the presented problem.
