Abstract

본 연구는 연구 개발단계[허용오차 ±25 %]에서 우리 나라 화학공장의 건설비를 보다 빠르고 쉽게 추산하기 위한 연구이다. 본 연구에서는 (1) 국산화인수(RE, RM, RL), (2) 가격차인수(αE, αM, αL) 등의 새로운 개념을 설정하여 이들의 상관관계를 고찰하고 국산화율에 따른 건설비의 변동관계를 정량적으로 보정할 수 있는 이론식을 유도하였으며, 이를 바탕으로 건설비를 일관성있게 처리하기 위하여 Factor System을 이용한 "한국화학공장 건설비 추산모델"을 제시하였다. 본 델의 타당성을 검토하기 위하여 실제 국내화학공장 건설비 사례를 조사하여 분석한 결과 실제 건설비 총괄인수와 3.33 %의 오차를 갖는 좋은 결과를 나타내었다. 또한 본 모델에서 총장치구입비를 계산하는데에는 QEEC컴퓨터 프로그램을 개발하여 사용하였다.
This study is to estimate the cost of constructing Korea chemical process plant at predesign stage. This study deduced a theoretical equation which can afford to modify quantitatively the changeable relation of the construction cost, resulting from the substitution of all foreign equipments for the domestic ones, by means of setting the new concepts-domestic factor(RE, RM, RL), the difference-value factor(αE, αM, αL) and considering the mutual relation between these two factors. The theoretical equation provided the estimation model for the cost of constructing Korea chemical process plant, based upon [factor system]. Analyzing the precendents in investigating the real cost spent for constructing the domestic chemical plants, which was carried out to find out the validity of this model, showed a good result error range of 3.33 % comparing with the overall factor in real construction cost.
