Process yield has been widely used on process performance. In this paper, we consider the supplier selection problem with multiple characteristics by using the yield index to compare two production processes and select one that has higher production yield. Testing hypotheses with two phases for comparing two processes are considered. Critical values of the testing hypotheses are calculated to determine the selection decisions. Sample size required for a designated selection power and confidence level is also investigated. These results provide useful information to practitioners. An application example on comparing two production processes is presented to illustrate the practicality of the proposed approach to a real problem in the factory.
