摘要
In this paper, a new quality control technique is discussed, in which the quality characteristic shifts with time. A trends semicircle control chart is proposed to control this type of processes effectively. An optimization model is suggested to determine the optimal interval of adjustment. We also discuss the average run length of the proposed control chart and the extension to the EWMA chart. An example is used to illustrate its application in a production process.
