Optimization of Reverse Production and Workshops Logistics Integrated Scheduling in End-of-life Products Disassembly Workshops
Aiming at the uncertainty of disassembly processes and logistics,an optimization method for the production and logistics integrated scheduling in a disassembly workshop is proposed to cooperatively optimize efficiency and cost.Firstly,the interaction factors between reverse production and reverse logistics in end-of-life product disassembly workshops are analyzed.A multi-objective scheduling model of the workshop is constructed,aiming at optimizing the maximum completion time and the advanced/delayed costs in reverse production and workshops logistics processes.Secondly,based on the logistics route decision,a mutation operator with gene repair is designed to improve the mutation accuracy of the NSGA-Ⅱ algorithm and enhances the solution effectiveness of the algorithm.Finally,taking a company′s mobile phone disassembly line as an example,the multi-size production and logistics examples are analyzed.The results show that as the number of adaptive guided vehicles increases,the delay cost of large and small size examples are reduced by 57.1%and 58.3%,respectively,verifying the effectiveness of the model.
