Abstract

스케줄링을 고려한 회분식 공장의 최적 설계는 초기 자본비를 점감시킨다. 중간저장탱크 조업 방식의 하나인 ZW(Zero Wait)에 대하여 세척시간(cleanup times)과 이동시간(transfer times)을 고려한 스케줄링 방법을 회분식 공장의 설계수식에 첨가함으로써 비선형 프로그램을 이용하여 장치의 최적크기와 생산 순서를 결정하는 방법을 제안한다. 두 개의 예제들을 통하여 본 방법의 효율성을 입증한다.

The optimal design of batch plants considering scheduling effects gives us savings of capital cost. Using a nonlinear programming formulation, which includes zero wait scheduling policy with cleanup and transfer times, we propose a method to obtain the optimum size and production sequence. The effectiveness of this method is verified by solving two problems.
