摘要

在控制图的经济设计中，参数的设计对于降低成本和时间起着重要作用。通过操纵样本量（n）和采样间隔（h），研究了双指数加权移动平均（DEWMA）模型对X控制图经济设计（ED）的影响。当物品的特征具有DEWMA模型时，可以获得最佳的尺寸和水平。当变化不确定时，DEWMA图表的最佳设计应更加保守，并应为消费者和生产商的利益而实施。

Economic Design of X̅ Control Chart under Double EWMA

Designing of parameters plays an important role in economic design of control charts for lowering the cost and time. Manipulating sample size (n) and sampling interval (h), the effect of double exponentially weighted moving average (DEWMA) model was studied for the Economic Design (ED) of X̅ control chart. Optimum sizes and level were obtained when the characteristics of an item possesses DEWMA model. When shifts are uncertain the optimal design for DEWMA chart should be more conservative and should be implemented for benefiting the consumers as well as producers.
