Development and application of intelligent scheduling system for vehicle wheels
The preparation of wheel production plans is one of the core tasks in the management of transit materials production plans.A reasonable production plan helps regulate the production pace of each order,ensuring smooth and orderly wheel production.Based on the scheduling of transit materi-als wheel production plans,taking into account factors such as rolling,heat treatment,outsourcing rough machining,precision machining,and inspection capabilities,as well as the logistics cycle be-tween insulation covers,tool switching,and sequential operations.By establishing a mathematical model and employing a multi-objective combinatorial optimization algorithm(MOCOA),intelligent scheduling of wheel plans is achieved,effectively addressing the production planning and scheduling issues arising from small batch sizes,multiple specifications and personalized requirements in Mas-teel's transit materials wheel production plans.The results of the system operation demonstrate that by repeatedly balancing the contractual delivery dates of wheel orders,unit capacity,material inventory,process paths,logistics cycles,equipment utilization rate,availability time of production lines and contract manufactory capabilities throughout the entire factory.The system generates interlinked pro-duction plans for each process unit,implementing a single plan creation process,which was previously taking two days,has been shortened to within 2 h,effectively enhancing the efficiency of wheel pro-duction scheduling.The reduction has led to a 20%decrease in wheel manufacturing lead times and a 20%reduction in inventory occupancy,aligning with the smart factory production requirements aimed at cost reduction and efficiency enhancement.
