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.

Planning phase became very important because the construction market in Korea is often unpredictable. The existing feasibility analysis cannot fulfill its purpose in development projects because they are based on intuitive approach rather than systematic approach. The purpose of this study is to make a prototype of feasibility model to be a good investment. To build the model, first, risk factors which can be occurred in project had to be selected. Risk factors were divided into several groups in basis of characteristical risk. Economical risk factors were input on financial analysis. Then, to catch the relevance and influence of all risk factors, influence diagram and decision tree were made. Finally, sensitivity analysis was activated, then what the critical factors were, and how those factors could be solved. Through these procedures, the feasibility model that was made in this study could include both quantitative and qualitative factors. This model is expected to be used as a guide of feasibility analysis including all risk factors and is to serve systematic frame in planning and feasibility stage.

한국해양연구소는 1973년 설립이래 서해안 조력발전 사업을 계속 해 왔다. 본 논문에서는 최근 조력발전사업의 해외동향, 특히 Rance 발전소 가동 실적, 영국의 Severn, Mersey강 하구 조력발전 타당성 검토사업 결과를 근간으로 하여 그간 이룩된 각종 기술의 개발 동향을 소개한다. 국내에서의 조력발전소 건설 타당성 검토는 1920년대 후반부터 시작되었다. 검토대상 지점은 경기도 강화군 남서쪽 동검도 일대의 해역이었으며 강화도 외측 조력발전 개발안이 처음으로 제안되었다. (중략)

The smart city public and private partnership project is a project to build and operate a sustainable city by investing land and capital in public-private partnership to build urban infrastructure and providing various urban services. It highly depends on the precise feasibility study and the projection of the various factors affecting the project during the planning stage to get the project successful. However, it is very difficult to predict the possibility of the project success in advance due to various physical and social factors. It is necessary to derive factors affecting the project at the planning stage and respond with appropriate analysis in order to solve these problems and to carry out a successful project. Therefore, this study derived preliminary components for feasibility study through previous studies and order status analysis and presented feasibility study components such as five-step processes, 10 process items, 19 analysis items, and 54 detailed analysis items through the Delphi method. It can be expected that this research is to contribute corresponding to diversified possible risks and facilitate the projects during the promotion.

The Metropolitan Area Green Heat Project (MAGHP), which collects unused heat gathered from power plants, steel works, landfills in western Metropolitan area and distribute it to integrated energy business (IEB) companies, is proposed for the purpose of enhancing energy efficiency and providing low-price heat for IEB companies. Therefore, in order to decide on whether to initiate the MAGHP, the economic feasibility analysis of the project is widely demanded. This paper attempts to consider and measure four economic benefits: heat supply benefit, production cost reduction benefit, greenhouse gas mitigation benefit, and air quality improvement benefit. In addition, the paper tries to conduct the economic feasibility analysis. The project requires three-year investment and thirty-year operation. Three important findings emerge from the analysis. First, its net present value is computed to be 1,269 billion won and more than zero. Second, its benefit/cost ratio is calculated to be 1.72 and bigger than 1.0. Third, its internal rate of return is estimated to be 24.26% and larger than the social rate of return, 5.5%. In conclusion, the MAGHP is socially profitable and should be conducted immediately.

The BTL project, 4 years since its operation, has benchmarked the PFI Project in Japan and has been introduced. Given the evaluation step to select a preferred bidder, in a technological factor, the basic plans are corrected and complemented, whereas in a price factor, the low price bidding system is being enforced. There is concern that how to select preferred bidders and how to operate project costs during operation and management period may be problematic. Thus, in this study, using the Analytic Hierarchy Process, the method of deciding the pribrity to select preferred bidders in an early stage of the project and the evaluation model to evaluate the validity of BTL project expenses in process of project enforcement are established. Targeting the group. composed of experts who have experiences in the BTL project. Then, the levelling of evaluation factors and grouping have been carried out as following: LCC analysis and disbursement for government including two more detailed factors.

The development project usually aims to get a certain amount of return for its investment in land and capital. The success of such project is dependent on the accurate analysis of the feasibility and for casting. It is, however, very difficult to predict due to various environmental factors. For this, it is necessary to constitute a systematic and objective method of analysis. However, there is no method of analysis for numerous qualitative factors, such as legal, environmental, marketability. Moreover, conventional methods have some limitations because they are processed without all the scope of analysis items and any evaluation criteria. Therefore, this study will provide computerization model for feasibility study focusing on the apartment development project by a pre-sall method. This research does casestudies to assess the feasibility analysis by the computerization model and compares to the results of the conventional methods. It showed that the evaluation results for the qualitative analysis were proportional to actual sale result. This implies that qualitative subjective factors have high correlation with sale rate and sale prices.

자판기 사업에 있어 환상 주입식의 마케팅정책은 이제 달라져야할 시점이 되었다. 자판기 사업은 '황금 알을 낳는 거위'다 라는 등식은 이제 더 이상 주효한 시점이 아니라는 사실을 냉혹히 인정해야 한다. 이 보다는 차라리 일정 고정수입을 보장하는 괜찮은 부업 아이템으로서 자판기 사업을 보는 시각을 가져야 한다. 사업에 대한 거품과 과대포장이 아닌 현실적이고 객관 타당성 있는 사업성이 차라리 보다 큰 대중적 소구력을 갖는다.
