摘　　要：预制构件生产的MES系统中需要使用模台排样任务结果以安排生产作业调度规划。针对生产排产作业时工装模具调度、模台排样周转时间长,模台面积利用率低的问题,主要研究了以矩形包络算法为零件预处理方式,并结合空余面积扫描算法的全局性及遗传算法的最优解,在多块模台上尽可能多地摆放预制构件进行生产的排样算法,在上层环节中可以通过CAM系统进行初始的预估排样,并以此作为排样任务结果,为后续MES系统中的生产作业调度规划提供较好的下料排样基础。In MES system of prefabricated component production,the results of die layout are used to arrange production scheduling.Aiming at the problem of tooling and die scheduling,long turnover time of die layout and low utilization rate of die area,mainly studies the layout algorithm based on genetic algorithm and combining rectangle envelope algorithm and spare area scanning algorithm to place as many prefabricated components as possible on multiple die tables for production,which can be realized through cam system in the upper link The initial estimated layout is used as the result of the layout task,which provides a good basis for the subsequent MES production scheduling planning.
