Control charts for processes subject to random shocks

Abstract

In this paper, a charting technique for controlling processes subject to random shocks is presented. This type of process is common in a high-yield production environment and the conventional Shewhart control charts are not efficient for its monitoring and control. This technique is able to detect process improvement, easy for decision making, and more concise and informative than other methods used for this type of process. In addition, it could provide diagnostic information which is highly useful in practice.
