Abstract
수요의 증가나 판매 가격 변경과 같은 시장 조건이 변화함에 따라 기존에 있는 다제품 생산용 회분식 공정에 대하여 새로운 장치를 추가하여 최적으로 개조하는 방법을 제시한다. 지금까지는 혼합정수 비선형 프로그램을 이용하여서 이 문제의 최적해를 구했으나 이 논문에서는 경험적인 방법을 제안함으로써 추가되는 장치가 놓이는 위치를 먼저 결정하고 비선형 프로그램을 이용하여 추가하는 장치의 최적크기를 구한다. 발표된 문헌 예제들을 통하여 본 방법의 효율성을 입증한다.
For the change of market condition such as increase of demand and new selling price, an optimal retrofit method is proposed through adding new equipments to existing multiproduct batch plant. Until now, the optimum volume and the appropriate position of adding equipments are solved using mixed integer nonlinear program. In this paper, a heuristic procedure is presented which first determines the positions of adding equipments. Then a nonlinear programming is formulated to obtain their optimum sizes. The effecti-veness of this method is verified by solving several literature problems.
