Collaborative sequencing optimization method for automobile multi-stage production line
To satisfy the requirements of automobile sequence in different processes of automobile production line,a collaborative sequencing optimization method for multi-stage automobile production line was proposed to improve the collaborative production capacity of multi-process workshop and reduce the production cost.The requirements of different processes were analyzed for automobile production line,and the re-sequence cost of the buffers was estab-lished by considering traditional optimization objectives such as the number of model changes in welding shop,the number of color changes in painting shop,the total overload and idle time in assembly shop,the material consump-tion rate in assembly shop.On this basis,a multi-objective optimization model of collaborative sequencing for auto-mobile multi-stage production line was established.A NSGA-Ⅲ based on inbound and outbound rules was used to optimize the model.Finally,the effectiveness of the proposed model and method was verified by a case study.
