Case Design and Implementation of Hypothesis Test Analyses for Attribute Measurement Systems

This paper is written by the author on the basis of a thorough understanding of the Measurement Systems Analysis (MSA) reference manual and summarizing its successful experience in the production practice of Weichai Power Co., Ltd. The typical attribute measurement system (go/no go gage) commonly used in the production site was chosen, and the consistency is determined by the Kappa value–Cross-tabulation method. This paper elaborated the detailed operation flow of the attribute MSA systematically and detailed introduce the specific design and implementation of each process, including the sample choosing, the determination of the random sequence of data collection, calculation, analysis, and the conclusion.
