The Correlation Study On Attribute Measurement System

Measurement system is one of the important factors taken into account by the project team during the key process. Though attribute data have been exclusively used in small and medium sized enterprises, they have not form the concept about the analysis of measurement system, and caused the larger error of measurement data when improving the quality, it even can not execute the improvement of quality effectively and cause larger loss for enterprises. Compared to the continuous measurement system, the attribute measurement system is seldom analyzed in our country. So, for its own character, it is urgent to analyze the measurement system to improve the efficiency and cut the cost.On the basis of related theory, this paper firstly discuss the analytical methods of measuring values, and analyze the correlation of existing measurement systems with actual cases, mainly calculate four kinds of proportion of agreements and correlations, then analyze the results. Secondly, the paper further study the attribute measurement system which can convert variable data into counting data in the method of constructing functions when there exist one, two or multi-value of product quality, compare it with continuous measurement system in terms of assessment methodoloty,and differentiate the absolute consistency and relative consistency with the help of cases. At last, we analyze a special attribute measurement system named destructive attribute measurement system, and carry out experimental design for the same sized sample. It may have both theoretical and practical significance to study attribute measurement system.
