It is highly recommended that companies should consider the organic complexes between variables and which new variable should be introduced. In addition, companies should determine to which extend they should respond to the diversification and complexity of consumers. In this regard, CLV (Customer Lifetime Vale) will be the main subject to be considered by companies in the future.

국내 반도체 산업은 불과 20년도 안되는 짧은 기간통안에 곽목할만한 성장을 하여 전세게 반도체 생산 규토 면에서 3위 국가로 부상하였으며, 기술 경쟁력 면에서도 한국인의 자존심을 그나마 지져왔다. 하지만, 반도체 제조는 가장 복잡한 제조공정의 하나로 분류되며, 이러한 복잡한 시스템을 통제하기 위해서는, 다양한 시스템 조건하에서 적절한 생산전략을 마련하는 것이 필요하다. 그러나, 반도체 제조 시스템에 대한 다양한 상황과 관련한 연구 많지 않다. 반도체 제

Scheduling semi-conductor manufacturing process systems is a complicated and difficult job due to such characteristics as reentry into manufacturing processes, high uncertainty of processes, and products and technologies changing rapidly. They have carried out many studies to find the efficient ways for semi-conductor manufacturing systems with a view to accomplishing the goals of systems like saving cycling time and increasing production quantity per unit time. The production flow in the semi-conductor industry has the most unique characteristics and makes it difficult to plan production and to schedule semi-conductor manufacturing. Currently, the scheduling methods in semi-conductor assembly processes follow the dispatching rule by simple FCFS(first come first serve). And backlog is operated as a buffer based on daily production quantity. In this study, therefore, we will apply various dispatching rules by real time basis and verify the effect and result of exact scheduling through simulation, based on the assumption that competitive advantages in production come from efficient inventory control and exact scheduling.
