Multi-Objective Production Scheduling Method for Decommissioned Power Battery Dismantling Workshop Based on Segmental Strategy

Unlike the forward assembly process, it difficult to achieve efficient scheduling of the production of disassemble production because most of retired power batteries are deformed. In this paper, a multi-objective production scheduling method for retired power battery disassembly workshop is proposed. Firstly, a segmented scheduling strategy based on two stages of battery pack and module is designed, then a multi-objective optimal scheduling model of disassembly workshop is established. The multi-objectives are reducing the completion time, energy consumption and equipment load. Finally, a genetic algorithm is used to solve it, and the chromosome coding method, cross-variation method and elite retention strategy in the genetic algorithm are optimized. The method is applied to the dismantling production of power batteries such as Yutong 161, and the results verify the feasibility and effectiveness of the proposed method.
