For last three years, our research team have conducted the project named "Development of construction project management technology based on BIM/GIS platform. "We developed construction cost estimation system as well as 3D modeling engine at the first two year and established a web-system which could estimate the benefits of the project and further analyze the economic and financial feasibility of the project. This paper mainly focused on the functions and specifications of web-system. The system was composed of two modules: economic feasibility estimation module and financial feasibility estimation module. While the economic feasibility estimation module determines economic feasibility of the project based on traffic demand forecasting from the public's perspective, the financial feasibility estimation module determine financial viability of the project using toll fee of the road from private entity's perspective. Compared with traditional feasibility study, the proposed system provide users with better flexibility which can make users easily to validate the project upon the change of project environments. The system was also verified with an already accomplished project. The verification showed that proposed system could provide satisfactory accurate results with reduced time and resources.

The purpose of this study is to construct a new model named Communication Consensus Value Weighted (CCVW) model based on inter-personal technical communication within a project team, and to design Feasibility Estimates Integrated Terminal System (FEITS) which is a subsystem of R & D Project Planning System/System Alternatives Feasibility Estimation System (RDPPL/SAFES) using the model as a key function for feasibility estimation in that system. This new model aims to integrate technical feasibility estimated by several estimators in the lowest level as the project work breakdown structure which is the indentical conception of a terminal system in RDPPL. The process to obtain the feasibility estimate integrated is presented in this paper.

The purpose of this study is to establish the function of a sub-system for System Alternatives Feasibility Estimation (SAFE) in R & D Project Planning Phase (RDPPL). It is the fundamental function of the RDPPL/SAFE that selected an optimal planning system alternative of all, considered at RDPPL/SAS, by logical means in view of feasibility. In this paper, improving the function of RDPPL/SAFE, mathmatical models in order to quantify methods determining and integrating the feasibility funtion in each terminal system with a multi-stage process are examined.

Making practical use of urban MAGLEV system which is tried by government includes technique development and railway construction. Because huge amount of money will be spent on this project, feasibility study is being carried out in order to check the feasibility and to devise the master plan in prior to making practical use of urban MAGLEV system. The key issues of feasibility study are possibility of technique development, economical feasibility, location of a model railway and the improvement of related laws and regulations. This paper shows the approach to solve these key issues.

It is important issue how to evaluate the economic feasibility of computing factors in the real world when we build ubiquitous spaces. In this paper, we propose a simple model that can evaluate the economic feasibility of mobile RFID-based ubiquitous computing system which enables seamless communication between offline and online via embedded computing factors in the real world. To achieve this, we explore the meaning of mobile RFID system, the difference between our research and extant researches concerning the evaluation of economic feasibility in RFID system, and propose the so-called 'Tag-based Evaluation Model' (TEM) which is an evaluation model to access the economic feasibility of mobile RFID systems. We also analyze the TEM via simulation cases based on proposed model and discuss the future of TEM.

도로 건설 프로젝트는 대규모의 자본과 공기가 소요되는 프로젝트이다. 본 연구에서는 도로 프로젝트의 타당성분석 시스템 요소 기술 고찰과 기존의 타당성분석 자료를 통해 현행 방법의 문제점을 도출하고 이에 대한 개선 방안으로는 프로젝트별 정보축적을 통한 타당성 정보모델 구축을 제안하고자 한다. 이는 합리적 의사결정을 지원할 뿐 아니라 프로젝트 진행과정에서 발생 가능한 리스크를 초기 예측함으로서 프로젝트의 효율적 수행을 도울 것이다.

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.

Many services have been served by the exiting subway systems since they have opened in 1975. But its efficiency and competition were going down because of the high construction cost and difficult connection with other transportations, etc. Otherwise, the light rail transit system is much lower construction cost than the subway and the high way building. Also those systems are good at the inexpensive operation cost, the fixed time and safety, the easy access. Recently, the several provinces are planning or advancing the light rail transit system because of these many benefits. Consequently, those system's economical feasibility analysis is required rapidly to show the resonable construction's cause and to get the private investment. This paper offers the system's economical feasibility through the several benefit analysis after the light rail transit system's construction.

This paper deals with the feasibility analysis and alternatives for infrared detector development. The purpose of this paper analyze development requirement and feasibility study in both technology and cost. We get raw input data for system engineering process from development and technical expert, and then analyze cost and technology for development feasibility, and alternative study. Infrared Detector is core component of Thermal Imaging System and developed by ADD from 2006 to 2008 year. Technical level is analyzed by TRL(Technical Readiness Level) and AOA(Analysis of Alternative) is done by development and production cost estimate. We use SEER-H tool for cost estimate, that is parametric cost estimate tool based on Knowledge Base. Also this paper presents risk analysis for project management because it is necessary to risk driver management during the infrared detector development. The result of IR Detector feasibility and alternative study will be used in technical and cost analysis. This study can help those who are related to the cost analysis and development feasibility of other weapons

New transport technologies have been rapidly developed and various transport systems are ready to introduce. However, there no exists effective decision making tools for pre-feasibility studies on transport systems. The pre-feasibility studies should provide reliable solutions about whether a certain transport system is feasible or not by cost-benefit analysis and effectiveness test of enhancing regional economy. This study introduces the smart transport investment/information system (SMARTIS) for supporting decision making with ease, fast and reliable methods. The SMARTIS incorporates travel demand estimates into the process of feasibility studies with automatic data processing methods to give reliable solutions quickly. The SMARTIS is expected to be informative for transit agencies, planners, and operators.
