考虑维护影响的动态控制图经济设计

Economic Design of Integrated Model of Maintenance Management and Adaptive Chart

针对现实中维护策略和控制图设计使用的是同一数据源的问题,论文基于数据共享的观点考虑了二者的联合设计问题。区别于以往研究中只考虑单扰动和静态控制图,论文以实际中更普遍的非对称双扰动情形为背景,以成本最优为目标,从经济设计的视角构建了维护策略和动态控制图的联合设计模型。仿真结果表明,相比于静态联合设计模型,动态联合设计模型的平均成本节省率达到6%以上,更具成本优势,因此具有更大的实用价值。

In practice, there＇s a close connection between maintenance policy and control chart design via data sharing. The joint design of these two is considered in this design. Different from the previous study only considering one assignable cause and static control chart, and with the aim of achieving the lowest total cost of the process, an integrated model of maintenance policy and adaptive chart under two assignable causes is constructed from the perspective of economic design. The simulation results show that compared with the static joint design model, the average cost savings rate of the dynamic joint design model is 6% higher, and it has more cost advantages, hence greater application value.
