方差监测的自适应累积和车身质量控制图研究
Research on Adaptive CUSUM Control Chart of Body Quality Control Based on Variance Monitoring
摘要
Abstract
Considering the high workload and extremely simple data processing in body welding quality inspection,an adaptive CUSUM control chart for variance monitoring was proposed herein for body welding quality control,whose principle was adaptively updated the reference values to monitor small variances infinitely in the process of body welding.Evaluation instance results show that,compared with traditional CUSUM control chart and exponential weighted moving average(EWMA) control charts,the adaptive CUSUM control chart based on variance monitoring is more sensitive to the small abnormal variation fluctuation.关键词
