汽车整车多级生产线协同重排序优化方法

Rush orders will occur in the process of the automobile producing, which interferes the execution of the original production plan and leads to higher production costs and a lower degree of sequential delivery of automobile orders for the initial paln. Therefore, a collaborative resequencing optimization method of the automobile multi-stage production line considering rush orders is studied. Firstly, the process characteristics of different production stages of automobiles are analyzed. Based on this, dynamic collaborative resequencing strategies are formulated for automobile orders in different production stages. Then, a dynamic collaborative resequencing optimization model of the automobile multi-stage production line is established, with the production cost and the order delivery delay as the optimization objectives. And a NSGA-II is used to optimize the model. Finally, the effectiveness of the proposed model and method is verified by a case study.
