초록

VE 분석은 사용자의 다양한 요구사항을 명확히 정의하여 기능과 성능을 확보함은 물론 비용절감이 가능한 대안을 제안하여야 한다. 하지만 현행 국내 VE 프로젝트는 프로젝트 참여자간 효과적, 효율적 커뮤니케이션의 어려움과 제약된 시간으로 인해 VE 기능분석에 대한 명확한 정의가 어려운 실정이다. 이로 인해 주로 국내 VE의 결과는 기존 시설 기능을 유지하면서 비용절감을 수행하는 방향으로 포커스 되어 있다. 따라서 본 연구는 VE 수행의 본래 취지에 맞추어서 사용자에 적합한 최적의 기능을 확보함은 물론 비용절감이 가능하도록 프로젝트 VE 참여자의 집단적, 협력적 방식이 가능한 QFD-VE 모델을 제안한다. QFD-VE 기법은 첫째, 요구기능의 정의 및 수정, 요구기능의 중요도 설정에 대하여 집단의사결정 적용이 가능하며, 둘째 VE 대안에 대한 인접시스템의 간섭, 충돌 여부를 프로젝트 VE 참여자가 협력적으로 검토할 수 있는 기법이다. 본 연구는 향후 QFD-VE 기법을 이용한 전산시스템 구현을 위해 수학적 모델을 함께 제시하였다.

VE analysis is a method to secure definite functions and performance by defining user's various requirements clearly and propose alternatives to reduce cost. However, the present domestic VE project has difficulty in defining design function analysis clearly due to time constraints as well as difficulty in effective and efficient communication between project stakeholder. Domestic results of VE were largely focused on reducing cost while maintaining the functions of the existing facility. Therefore, this study aims to secure the optimal functions for users according to the original intent of user requirements through QFD-VE model which project VE participants can make collective and cooperative decision making. QFD-VE is a technique that first, it can make collaborative decision making in defining and modifying of design function and setting the importance of requirement function. Second, it allow project VE participants to check design interference and conflict between neighbor systems. This study also provided a mathematical model for implementing the computer system using QFD-VE in the future.
