Abstract

Reconstruction and remodeling have been introduced as a part of renewal (redevelopment) projects for old apartments built after the mid-1970's and government policies for revitalizing each project has been changed continually. However, the frequent changes of the policies have caused conflicts among business entities in selecting business methods. The conflicts from their early stages have made serious problems in the entire business process. Therefore, this study deduced factors of business selection by applying comparison analysis between the two business projects on how certain factors have an influence on selecting reconstruction and remodeling business projects. Based on the analysis, four categories and 26 factors were finally selected. After then, the priority of each selection factor was deduced through the AHP method and PROMETHEE method used for analysis of relative importance and impact values regarding to the business selection.

1970년대 중반 이후 건설된 노후아파트의 재건축(재개발) 사업의 일환으로 재건축과 리모델링이 도입되었고, 각 사업의 활성화를 위한 정부의 정책도 지속적으로 변화하고 있다. 정책의 빈번한 변화는 사업체들 간의 사업방식 선택에 있어 갈등을 야기시켰다. 사업 초기단계의 갈등은 전체 사업 과정에 심각한 문제를 일으켰다. 따라서 본 연구는 재건축과 리모델링 사업의 비교분석을 통해 두 사업 선정 시 특정 요인이 어떤 영향을 미치는지에 대한 사업선정 요인을 분석하였다. 분석에 기초하여 네 개의 범주와 26개의 요인들을 도출하였다. 그 후 사업 선택과 관련된 상대적 중요도와 영향 값의 분석에 사용된 AHP 방법 및 PROMETHEE 방법을 통해 각 선정 요소의 우선순위를 도출하였다.
