Mass customization (MC) is a stateoftheart production model,its production varies with customer needs,and is unpredictable. Mass customization has the characteristics of short product development and life cycle, low production volume and short equipment adjustment time.Because the current control chart was not fully applicable to this production mode, a joint statistical process method for the production process monitoring of mass customization manufacturing enterprises was proposed, which was an index-weighted moving average control chart for mass customization manufacturing system based on Q statistic. The statistical toolbox of MATLAB was used to simulate a group of random data similar to mass customization, the data were converted into Q statistic by using MATLAB, and then the feasibility and prediction accuracy of this joint statistical process method were verified by using the statistical analysis and chart function of Minitab.
