摘要

摘要本文开发了事件间隔时间（TBE）控制图，用于监控多条相关生产线的流程。为此，提出了休哈特型和EWMA型TBE图。copula方法用于描述生产线之间的相关性，齐次泊松过程用于对缺陷数量进行建模。使用平均信号时间度量来评估所提出的方法的性能。数值研究表明，EWMA-TBE图的一致性优于休哈特型图。最终，EWMA-TBE图表被应用于监控两条和四条生产线的两个真实世界的流程。

Monitoring processes with multiple dependent production lines using time between events control charts

Abstract This article develops Time Between Events (TBE) control charts to monitor processes with multiple dependent production lines. To this end, a Shewhart-type and an EWMA-type TBE chart have been proposed. The copula approach is used to describe the dependence between production lines and the homogeneous Poisson process is considered to model the number of defectives. Performance of the proposed methods is evaluated using average time to signal metric. The numerical study showed that the EWMA-TBE chart uniformly performs better than the Shewhart-type chart. Eventually, the EWMA-TBE chart is applied to monitor two real-world processes with two and four production lines.
