Multi-objective Analysis for Mixed-model Assembly Line Using Elite-induced PSA

Abstract

There exists a trade-off between amount of inventory and line stoppage time in mixed-model assembly lines. It becomes extremely important to reveal such trade-off relationship or to engage multi-objective analysis for the decision making on product sequencing. Previously, we compared the performance of a traditional weighting method and a new meta-heuristic approach like PSA and revealed respectively the advantages and disadvantages of both methods. In this study, we propose a new method termed Elite-induced PSA having only good properties of both methods. Through case study, we will validate its effectiveness.
