G/G/S系统队长的优化控制

Optimization of Control Charts for G/G/S Systems

制造系统生产流水线由于受随机干扰的影响,经常出现待加工工件积压或短缺的现象。针对这种情况,给出G/G/S系统队长控制图的优化设计方法。该方法对给定的第一类风险,结合工件短缺的惩罚费用和积压的存贮费用,提出合理度量控制图损失的损失函数及控制限确定方法。通过与已有方法的比较分析,证明该方法是有效、可行的。

This paper presents an approach to the optimization of control charts for G/G/S systems. For the first risk, the paper gives the loss function of the control charts and the control limits. By comparison with other methods, the approach is effective and feasible.
