Abstract

Due to the low interest rates of banks according to the breakdown economy after the global financial crisis in 2008 As a substitute for financial products, the investment demand has been increased for rentable investment funds such as commercial building and officetel. However, the problems such as oversupply, decrease of a rental profit and negative perception of development projects have been occurred. One of the primary problems is the existing deterministic method of project feasibility analysis. Therefore, the objective of this study is to develop feasibility model by applying system dynamics method in residential officetel. To achieve the objective, first, the previous studies are investigated. Second, the causal loop diagram is structured based on the collected data. Third, the feasibility model is developed through the causal loop diagram. Fourth, the effectiveness is validated and compared to collected actual data. The proposed model can be helpful whether or not conduct execution of an officetel development project to the decision makers.

2008년 세계 금융위기 이후 경기침체에 따른 은행의 저금리로 인해 금융상품의 대체재로 상가 오피스텔과 같은 임대수익형 투자 상품에 대한 관심과 투자수요가 증가했다. 이는 오피스텔 개발의 양적인 팽창에는 많은 기여를 해왔지만 과잉공급, 임대 수익률 감소, 그에 따른 개발사업의 부정적인 인식 확산 등 문제점을 야기했다. 문제점의 원인은 하나의 대표 값으로 제시하는 기존의 잘못된 사업타당성 분석에서 찾을 수 있다. 이에 본 연구에서는 시스템다이내믹스를 활용한 오피스텔 사업타당성 분석 모델 개발을 목적으로 한다. 이를 위해 첫째, 사업타당성 연구현황을 파악하고 시스템다이내믹스에 대한 문헌고찰을 수행한다. 둘째, 타당성분석에 있어 고려해야 하는 변수들을 선정하고, 인과지도를 작성한다. 셋째, 인과지도를 토대로 모델 구축을 수행한다. 넷째, 오피스텔 사례와 비교하여 적합성과 유효성을 검증하고 타당성을 비교한다. 본 연구에서 제안한 모델은 오피스텔개발사업의 실행여부를 결정하는 의사결정권자 및 이해관계자에게 의사결정 도구로써 도움을 줄 수 있을 것으로 판단된다.
