# 考虑预防保养之X¯管制图经济–统计设计The Economic-Statistical Design of X¯ Control Charts under Preventive Maintenance

Human power has gradually replaced by automated production equipment. Therefore, during the production process, maintaining the automated production equipment in order to reduce any production variations can effectively increase product quality and lower production costs. A traditional control chart is designed on the basis of statistics. An economic control chart may achieve a lower cost, but it does not perform well in some statistic features, so the two are combined in order to compensate each other. Even so, the design of a general control chart does not consider the preventive maintenance of machine equipment. Therefore, the economic-statistical design of X¯ control chart is developed under a consideration of the preventive maintenance of machine equipment in this study. Numerical example is also used to demonstrate the model’s working.
