Abstract :
Process Capability Index is a widely used tool for quality evaluation. Available methods of Process Capability evaluation are limited to machining process. There are no suitable methods for comprehensive evaluation of total producing process capability. In this paper, a comprehensive evaluation model of product producing process capability is proposed, so that data of all stages can be fully used. Methods for machining capability evaluation are extended to purchasing, assembling and delivery inspection and an index system of producing process capability evaluation is presented. In addition, analytic hierarchy process is used to determine the weight of each stage and then producing process capability index is achieved by summing. Finally, an application example is analyzed to show that the entire producing capability can be evaluated objectively. It should play an important part in monitoring and improving producing process capability.
