摘要: 晶圆代工是国内最热门的产业之一,但是在竞争激烈的环境下,各厂纷纷寻找降低成本的解决方案,其中零件库存问题的重要性也逐渐浮现出来。由于晶圆厂制程复杂、设备精密度高、维修零件昂贵及其采购前置时间的不易控制等因素,都使得零件的存货金额居高不下。
本研究以各案探讨的方式,以台湾某晶圆代工厂为例,探讨在4座同性质的8寸晶圆厂中,改变其维修零件库存集中程度对库存成本的影响,同时在不改变服务水准的条件下,寻找最低的总库存成本,并协助业者在考量本身库存的现实环境下时,做出最有利的库存决策方式。
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.
