Supplier Selection based on Process Yield for LED Manufacturing Processes

摘要

In today's fierce competitive business environment, it is very essential to work with right suppliers in the supply chain systems. Consequently, supplier selection problem is very important and has received considerable attention. In the supplier selection problem, quality is the most popular criterion. In the paper, we consider a supplier selection problem of comparing two suppliers and selecting the one that has a significantly higher process capability for the light emitting diode (LED) assembly process with multiple characteristics. Testing hypotheses for the LED assembly supplier selection are presented. For practitioners' convenience, the corresponding critical values for the supplier selection in LED assembly process are tabulated. For illustration purpose, an application is presented.
