| Summary: | 碩士 === 國立交通大學 === 管理學院碩士在職專班工業工程與管理組 === 98 === IC Industry has been developed more than 30 years in Taiwan. As a result of Government support actively and under the Industrials support, Taiwan became the 2nd large base for the Fabless IC design houses in the world. And also became the 4th large production country from the excellent manufacturing capacity and play a decisive role in the globe semiconductor market. The operation strategies were focus on Fabless IC design and without their own manufacturing plant. The professional subcontractors were in charge of the manufacturing. All of the production activities must to outsourcing cause of they did not have their plant and plan the production schedule was according to the forecast of market ahead of time only. They must to negotiate with subcontractors for production capacity. Outsourcing production delivery day became unreliable when the subcontractors production capacity near to full loading. When the market trend turn down, safety stock and WIP will affect the money overstocks accumulated and inventory cost was been increased. Under the violent market changed and short product lift time, the traditional supply chain management was base on the sales forecast to plan the production schedule. And then, we know the forecast was always not accurate, there was always having a lot of inventory in the warehouse but without the product that customer need. And then, released the super hot run to fulfill the customer actual demand became normal afterward make the supply chain executed become unstable. In consideration of the interfere in supply chain management from the forecast uncertainty, this paper will base on the Theory of Constraint and implement Demand Pull in stead of the forecast production; and use the target inventory level to manage inventory. According to the literatures discuss and the company’s history data verify, we are trying to improve the inventory level and also fulfill the customer’s demand with lower inventory level. And then to enhance the company’s competition flexibility, increase its profit and return on investment rate.
