사업기획 및 타당성분석단계는 사업을 추진하는데 가장 큰 영향을 미치는 단계로써, 정확한 프로젝트 타당성 검토 수행은 프로젝트를 추진하는데 결정적인 기회를 제공해주므로 직관적인 접근방식보다는 객관적이고 정확한 방법의 제시가 요구되는 바이다. 사업타당성을 정확하게 분석하기 위하여 본 논문에서는 프로젝트 진행에 영향을 주는 리스크 인자를 식별하고 이 인자들을 성격별로 그룹화한다. 소규모 임대주택의 사례를 바탕으로 기존 방식인 금융부분의 프로젝트 타당성 분석을 실시한다. 위에서 식별된 리스크 인자들 중 금융부분을 포함하여 인자들간의 상관관계를 Influence Diagram으로 파악하여 리스크를 분석하고, 각 인자별의 중요도를 판별하기 위한 민감도 분석을 실시한다. 이와 같은 과정을 통하여, 기존의 프로젝트 타당성분석에서 사용하는 금융부분의 타당성분석 뿐만 아니라, 프로젝트 진행시에 나타나는 비정형적이고 주관적인 요소들을 리스크 인자로써 포함하여 분석할 수 있는 장점이 있다. 또한, 도출된 모든 리스크 인자를 정량화하여 객관적인 분석 및 의사결정을 할 수 있기 때문에 기존 방법보다 발전된 프로젝트 타당성 분석 방안을 본 논문에서 제시하였다.

Due to recession in real estate market, interest of risk analysis is increasing. Feasibility study in the first stage takes a great role in a project. There are not objectified tools which are able to cope with uncertainty of project, and feasibility study based on selected method of determinism does not include liquidity of weight risk. Also, shortage of consideration for subjective and atypical external factors causes inappropriate results. Therefore, this study proposes feasibility study model focused on risk factor influences in construction cost and sales cost. Considering effective level of cost based on objective risk factors and probable weight of risk by this model, real workers are able to bring correct and scientific decisions better than former method based on selective analysis of real estate development.

A GDHS(Geothermal District Heating System) is a heating system supplying a group of districts with heat extracted from geothermal sources. The advantages of GDHS include saving fuel consumption as well as reducing air pollution. This paper presents a case study for the economic feasibility model and analysis of a GDHS with which central/individual heating systems are replaced. Configuring to a simplified GDHS which consisits of subsurface systems, surface systems, and transmission/distribution systems, we find out the properties of the system and the model parameters affecting the initial investment/operating costs in order to develop a classical economic feasibility model given geothermal temperature. Based on our model parameter space, we analyzed the geothermal development project of the Jejoo Island probabilistically given prior information such as the expected geothermal power, the demand size and the length of transmission/distribution pipes.

The starting point of successful building production process is the feasibility study of the project. If the feasibility study is poor which is affected in direct production processes such as designing and engineering, it incurs a great unrecoverable loss to the company. The government institutionalized the feasibility study for projects that budgets over 50billion won in an effort to ensure competitiveness of the construction industry after IMF; however, the system and effort to created systematic studies or guidance preparation for private construction development projects are lacking in great deal. Therefore, the objective of this study is to establish the analysis factors of feasibility study and evaluation standard by systematic analysis in consideration of the changes of various variables and mutual relationships using system dynamics technique for office buildings among commercial buildings.

New product development (NPD) is defined as the transformation of a market opportunity and a set of assumptions about product technology into a product available for sale. Managers charged with project selection decisions in the NPD process, such as go/no-go choices and specific resource allocation decisions, are faced with a complicated problem. Therefore, the ability to develop new successful products has identifies as a major determinant in sustaining a firm's competitive advantage. The purpose of this study is to develop a new evaluation model for NPD project selection in the high -tech industry using support vector machines (SYM). The evaluation model is developed through two phases. In the first phase, binary (go/no-go) classification prediction model, i.e. SVM for high-tech NPD project selection is developed. In the second phase. using the predicted output value of SVM, feasibility grade is calculated for the final NPD project decision making. In this study, the feasibility grades are also divided as three level grades. We assume that the frequency of NPD project cases is symmetrically determined according to the feasibility grades and misclassification errors are partially minimized by the multiple grades. However, the horizon of grade level can be changed by firms' NPD strategy. Our proposed feasibility grade method is more reasonable in NPD decision problems by considering particularly risk factor of NPD in viewpoints of future NPD success probability. In our empirical study using Korean NPD cases, the SVM significantly outperformed ANN and logistic regression as benchmark models in hit ratio. And the feasibility grades generated from the predicted output value of SVM showed that they can offer a useful guideline for NPD project selection.

Although there are many old school buildings that is more than 40 years in Korea, it is difficult to rebuild all of them due to limitations in budget management. Therefore, objective feasibility evaluation criteria are necessary to determine which school buildings should be rebuilt preferentially among the numerous old school buildings. One of the rebuilding feasibility evaluation items, economic evaluation generally requires documents such as construction statements and facility drawings. However, because most buildings older than 40 years do not have these documents, an economic analysis model that requires only basic building information should be developed. In this study, the economic analysis model that can be used for evaluating the rebuilding feasibility only with the number of years, total floor area, and structural information of school buildings was established. This model can contribute to the objective feasibility evaluation of old school buildings because it can evaluate numerous buildings on the same criteria based on basic building information.

This study suggests how to evaluate the business model feasibility of Geographic Information Service(GIS) before they are commercialized in Ubiquitous Environments. It suggests the evaluation framework for business feasibility in order to provide a successful method. The framework is consisted of various evaluation dimensions and Indices like technology, marketability, business ability, customer satisfaction and business risk. From this research, we will anticipate a high rate of successful GIS business in respect to various elements related in the commercialization of the former business in ubiquitous environments.

This study deals with verifying the design feasibility, of an independently driving hydraulic system for disaster response purposes, through an analytical approach. The development target is a system in which four traveling motors are driven independently, and must be easy to operate even under conditions in which different loads are applied to the traveling motors. In order to be suitable for complex work, the hydraulic system was designed using the main control valve with a pressure compensation function. If we can develop an analytical model that reflects the specifications and functions of the parts through the analysis program, we can verify the validity of the design before we make the prototype. The purpose of this study therefore, is to verify the feasibility of designing an independent drive hydraulic system through the development of an analysis model from the viewpoint of complex work. The analysis program uses Simulation X.
