基于马尔可夫链模型的B&L VP (X)控制图统计性能分析
Statistical Performance Analysis of a VP (X) Control Chart with B&L Switching Rule by Using a Markov Chain Model
摘要
Abstract
In statistical process control, variable parameter (VP)X chart is widely used. To improve the performance of the VP X chart, Bai & Lee ( B&L) switching rules are applied to design the VP X chart. By this method, a Markov chain model is developed to obtain the expressions of Average Time to Signal ( ATS), Adjusted Average Time to Signal ( AATS) , and average number of switches ( ANSW). To evaluate the performance of the proposed method, comparison is done between the chart designed by the proposed method and the existing VP X chart by using two samples. Results show that, with the same average run-time, the proposed method outperforms the existing VP X chart in both shortening the alarm time and in reducing the number of switch times. The larger the parameter L is, the better the performance of the proposed method is.关键词
