论文摘要
传统上用于质量监控的控制图，也可以用于监视系统的可靠性。换句话说，它们可以应用于检测系统故障行为的变化。除了开发与可靠性监视更兼容的图表外，此类目的还施加了修改传统的控制图。后者开发的类别称为概率限制控制图。现有的可靠性监视控制图仅专用于二元状态系统，并且不能同时使用它们来监视多个状态。因此，本文开发了一个控制图表的设计，该设计可容纳多状态系统，在此称为角控制图，它代表了概率限制控制图的新版本。此设计还可以同时和单独监视状态转换。实施说明性系统示例以探索新设计的监视程序，并证明其效率，有效性和局限性。
Control charts, as had been used traditionally for quality monitoring, were applied alternatively to monitor systems' reliability. In other words, they can be applied to detect changes in the failure behavior of systems. Such purpose imposed modifying traditional control charts in addition to developing charts that are more compatible with reliability monitoring. The latter developed category is known as probability limits control charts. The existing reliability monitoring control charts were only dedicated to binary-state systems, and they can't be used to monitor several states simultaneously. Therefore, this paper develops a design of control charts that accommodates multi-state systems, called here as the Angular Control Chart, which represents a new version of the probability limits control charts. This design is able to monitor state transitions simultaneously and individually in addition. Illustrative system examples are implemented to explore the monitoring procedure of the new design and to demonstrate its efficiency, effectiveness, and limitations.
