Abstract: Under the circumstance of mass production, in order to solve the problems, such as the unstability of the workshop quality, high percent defective and more wastes, the workshop quality stability control system was put forward. The principle and the functions of the system were constructed. In this system, the workshop quality stability was analyzed from the view of workshop process quality and product quality. Because of the complexity of relationship between workshop process quality and product quality, the method of association analysis based on the grey system theory between workshop process quality and product quality was developed. With the system and method, how to find the workshop process factors which influence product quality and the control of workshop quality stability can be realized.
Key words: workshop process quality; product quality; grey system; association analysis
