Control charts are efficient process monitoring tools used to distinguish between assignable and natural variations. This article presents a new time-between-events chart to monitor the scheduled time. In particular, exponentially modified Gaussian distribution is considered in the construction of the control chart. The performance of the chart is evaluated in terms of average run length and coefficient of variation of the run length. To show the significance of the proposed chart, the data on time in hours between the detection of cancer cells using 3 um erlotinib and schedule time in minutes of an employ are considered.

使用指数修正的高斯分布监控计划时间

控制图是有效的过程监控工具，用于区分可分配的变化和自然变化。本文介绍了一个新的事件间隔时间图表，以监视计划的时间。特别地，在控制图的构造中考虑了指数修正的高斯分布。根据平均游程长度和游程长度变化系数评估图表的性能。为了显示建议的图表的重要性，考虑了使用3 um厄洛替尼检测癌细胞之间以小时为单位的时间数据和以分钟为单位的调度时间所用的时间数据。
