Semiconductor Wafer Fab is one of the Two-Trillion Twin-Star Industries Development Plan. The performance of the Warehouse management process shall affect the effectiveness of the Warehouse management of the semiconductor wafer Fab, thereby affecting the product delivery time, logistic and cost of manpower of the company. Hence, it is critical to investigate ways to improve the Warehouse management process. This dissertation primarily adopts an investigation method that utilizes Multiple Criteria Dicsion Making (MCDM) Analytic Hierarchy Process (AHP) to derive the aspects and affecting factors to be considered when improving the Warehouse management process. Furthermore, the Grey Relational Analysis is used to investigate the relativity between evaluation of the Warehouse management with Barcode and RFID and the evaluated aspired value, thereby forming a reference basis for the warehouse department of a case company to follow in order achieve the aspired value.
