Semiconductor foundry industry is one of the most popular businesses in Taiwan. In serious competition environment, each of companies tries to fine the best solutions to reduce their inventory cost, so inventory control of spare parts became the one of the most important activities for those companies. Due to the complex process, high precision machines, expensive spare parts, and unstable purchasing lead-time in this industry, it made these companies with high inventory. This research is a case study of the manufacture in Taiwan who is specialized in IC foundry. This study aims to find the relationship of inventory cost of spare pats when we change centralizing ratio of spare parts location. In the meantime, we study to find the lowest inventory cost without change service level. According to themselves condition, we hope this study can help to make a good decision to fit them.
