有两种主要类型的变化，即分别导致控制和失控状态的常见原因和特殊原因。控制图是用于区分过程的这两种状态的常用工具。运行规则计划与控制图的实施是一个有吸引力的过程监控方法。本研究的目的是描述运行规则方案的方法，并讨论其实施不同类型的控制图。我们考虑了无记忆图，即X、S和R图。研究表明，效率增益取决于用于实现给定规则的决策点的数量。此外，运行规则方案的优越性对于不同类型的位置和分散图可能有所不同。一个使用数据集的应用实例也包括在研究中，以供实际考虑。版权所有© 2015约翰威利父子有限公司.
There are two main types of variations, namely, common and special causes leading to in‐control and out‐of‐control states, respectively. Control charts are popular tools used to differentiate between these two states of a process. Implementation of runs rules schemes with control charts is an attractive approach for process monitoring. This study is designed to describe the methodology of runs rules schemes and discuss their implementation for different types of control charts. We have considered memory‐less charts, namely, X¯ , S, and R charts for our study purposes. It is examined that the efficiency gain depends on the number of decision points utilized to implement a given rule. Moreover, superiority of runs rules schemes may vary for different types of location and dispersion charts. An application example using a dataset is also included in the study for practical considerations. Copyright © 2015 John Wiley & Sons, Ltd.
