Multivariate Bayesian VSI control chart

Abstract

In this paper, research was conducted on a multivariate Bayesian variable sampling interval (VSI) control chart to address the problem of insufficient research in the area of Bayesian multivariate control charts with variable parameters. Bayesian multivariate control chart was constructed and control strategies on variable sampling interval and variable control limits were designed. Cost model was built and the corresponding parameters of cost and control chart were determined through researching in enterprise. Monte Carlo stochastic simulation was adopted to verify the economical and statistical advantages of Bayesian multivariate control chart. This study provides supports for in-depth study on Bayesian multivariate control chart with variable parameters.
