초록

범용 화학공정 동적모사기에 적합한 모사기의 구조, 적분전략, 입력언어, 계산효율 향상을 위한 방법들을 제시하였고, SCI(Sequential Clustered Integration)를 기본으로 하는 원형(prototype) 모사기를 개발하였다. SCI방식은 SMI(Sequential Modular Integration)의 일반적인 형태인데, SEI(Simultaneous Equation Integration)의 장점을 수용하였기 때문에 SMI 나 SEI에 이르기까지의 다양한 수준의 커플링이 가능하다. 예제를 통하여 SCI의 성능에 많은 영향을 미치는 clustering의 기준에 대하여 연구하였고, 모사기의 성능을 평가하였다.

A simulator structure, integration strategy, input language and simulation technique are presen-ted in order to develop a general purpose chemical process dynamic simulator, and a SCI(Sequential Clus-tered Integration)-based prototype simulator is implemented. The SCI is a general form of SMI(Sequential Modular Integration) but has better performance then SMI and SEI(Simultaneous Equation Integration) with respect to computational efficiency and flexibility of applications. The SCI approach is capable of introduc-ing various mode of coupling of the process units, actually, from SMI to SEI within a single simulator structure. Examples are presented to study the clustering criteria which have significant influence on the performance of SCI and to illustrate the system performance.
