根据ＦＭＳ资源、加工任务、零件工艺提出了零件分批算法。该算法在零件交货期约束下，以机床负荷平衡为目标，搜索零件集合，找出最合适的零件组合形成零件加工批。此算法为简化ＦＭＳ的动态调度和提高系统生产率创造了条件。仿真结果表明分批算法是行之有效的。 According to FMS resources, processing tasks, part technology proposed parts batch algorithm. The algorithm, under the constraints of the delivery date, targets the load balance of the machine tool, searches for the part assembly, and finds out the most suitable part combination to form the part processing batch. The algorithm to simplify the FMS dynamic scheduling and improve system productivity to create the conditions. Simulation results show that the batch algorithm is effective.
