다양한 대안이 고려되는 SOC사업을 종합적으로 진행할 시 투입가능한 재원의 한계는 개별사업의 중요도를 바탕으로 한 투자우선순위를 필요로 한다. 특히, 댐 직하류 하천정비사업과 같이 내재된 가치가 복합적이고 판단기준이 다양한 경우 의사결정의 어려움에 직면할 수 있는데, 이는 다기준의사결정 기법을 활용함으로써 해결할 수 있다. 본 연구에서는 다기준의사결정 기법 가운데 다양한 대안을 고려할 수 있고, 투자우선순위 결정에서 장점이 있는 PROMETHEE을 활용하여 댐 직하류 하천정비사업 33개 대안에 대한 투자우선순위를 결정하였다. 이를 위해 댐 직하류 하천정비사업의 목적과 기능에 입각하여 7가지 세부 평가기준과 평가속성을 결정하였고, 평가기준별 가중치는 AHP 기법에서 제안하는 고유벡터법에 의해 산출하였다. 이를 바탕으로 PROMETHEE를 수행한 결과, 총 33개 대안 가운데 주암조절지댐, 운문댐, 용담댐 순으로 투자우선순위가 높은 것으로 나타났다. 본 연구에서 제시한 댐 직하류 하천정비사업의 투자우선순위는 향후 우선순위가 높은 대안을 대상으로 동시투자 혹은 단계적으로 투자하기 위한 의사결정자의 정책결정에 도움을 줄 것으로 판단된다.

There are two methods for evaluating two or more mutually exclusive projects. One is a total investment approach and the other is an incremental investment approach. The former can rank projects by the criterion of the net present value, but the latter can't do it. An incremental investment approach is only possible when all pairwise alternatives are compared. Thus an incremental investment approach is superior in ranking them over an incremental investment approach. To do so, a principle of comparison must be established. Comparisons of profitability are reasonable when operating the same amount of investment over the same period of time. One principle is that all projects are invested in the largest of the projects. Another principle is that all projects are invested during the longest project life of the projects. In this paper, even if the principle is followed, it will be shown that the external rate of return fails to rank them. However, the productive rate of return criterion would prove to be able to rank them like the net present value standard, provided that the principle of comparison is kept. In addition, rate of returns can be assessed so that all mutually exclusive projects can be compared at once, such as on the criterion of the net present value. That is, it can be also compared with many other returns, such as the profit rates on financial investments or real investments.

본 논문에서는 경제성 평가를 기반으로 하는 배전 설비투자 우선순위를 결정하기 위하여 배전계통 구성, 설비 및 부하정보를 이용하여 배전계통을 모델링 하고, 현 계통의 신뢰도를 개선하기 위한 방향으로 설비투자 대안들을 설계한 다음, 이 대안들을 대상으로 신뢰도 및 경제성을 평가하는 모델을 제시하였다. 이러한 투자대안들의 신뢰도 영향과 경제성을 분석하기 위하여 한전의 주요 배전설비(15종)의 신도율(시변고장율)과 설비투자시 영향을 받는 고객들의 정전비용을 적용하여 경제적 효과를 산출하였으며, 이러한 투자 방법론의 유효성을 검증하기 위하여 한전의 배전사업소 실제 투자안을 대상으로 하여 경제성 평가를 수행한 결과와 비교분석하였다.

Decision Support System(DSS) is an advanced information system concept prevailing since 1980s. It supports managers' decision making activities by providing not only information but decision alternatives. It essentially consists of the components of database, modelbase and dialogue systems. With the development of its databases, POSCO needs a number of modelbases in establishing DSSs in various areas such as production planning and investment. This research particularly focuses on establishment of a mid-and long-range investment DSS and investigates the necessity and the problems of an investment DSS and the decision criteria for investment priority. We (1) propose a modelbase which uses the concepts of Analytic Hierarchy Process(AHP) and Zero-Base Budgeting(ZBB), along with an appropriate scoring method, database and dialogue system to support the investment manager in evaluating investment proposals ; (2) implement the system using relational database management system ; and (3) discuss the results of implementing the investment DSS.

The purpose of this study was to examine changes in the household investment planning according to the family life cycle, to improve the household investment planning process, and to develop research model. The results were as follows : Household investment planning varied with stages of the family life cycle because the stock of resources shifted and financial goals changed as the family life cycle stage changed. The main financial goals of family in each stage of the life cycle were the purchasing of house in the establishing stage, children's education and marriage in the extending stage, and the elderly's economic welfare in the diminishing stage. Also, in the Ⅰ & Ⅱ stage the most important investment goals were the purchasing of house, children's education in the Ⅲ stage, children's marriage in the Ⅳ stage, and the elderly's economic welfare in the Ⅴ stage. Therefore, the financial goals were recognized as the important goals underlain the investment-planning goals, and alternatives for the accomplishment of investment-planning goals were determined. The results of this study can contribute to establish the long-run investment planning process and improve the level of household's financial well-being.

기업들은 급변하는 시장상황의 대처하고 경쟁우위 확보하고 비즈니스 목표달성을 위해 정보기술 투자에 지속적으로 비용을 지출하고 있다. 많은 기업들이 제품 품질에 대한 다양한 정보들은 통합적으로 관리하고 기업간의 정보 교환을 원활히 수행하기 우한 지원시스템을 갖추고 있지 못한 상화에서 고객에 대한 품질문제 발생시 종합적이고 체계적인 대은에 큰 어려움을 겪고 있다. 이러한 문제점을 해결하기 위하여 관련 업체의 품질관리 수준 및 업무에 맞는 정보관리 시스템의 도입이 절실히 요구되고 있으며, 본 연구에서는 정보시스템 개선을 위한 과거의 투자의사결정방법보다 합리적이고 객관적인 투자의사결정을 하기 위해 사례연구를 실시하였다. 사례연구결과에서 투자예산과 개선항목에 대한 정규종합우선도합의 증가 값의 관계가 정비례하지 않음을 알 수 있었다. 즉, 매년 정보시스템 개선을 위한 예산 책정시 한번에 많은 금액을 책정하기 보다는 적정투자예산을 여러 해에 걸쳐 지속적으로 투자함이 유리하다는 결론이다.

In sequential capital allocation processes, the information on the future availability (flexibility) of invested funds provides a decision maker with additional insight into the characteristics of alternatives. The investment decision with consideration of flexibility and profitability results in more wealth accumulation than the decision without considering flexibility does in sequential investment processes. To utilize the information on the flexibility under certainty, the PV/FI decision model is developed.

This study defines the Next Generation System(NGS) built by domestic financial businesses and classifies their architecture into two typical types according to the duration of the project and the relative cost of IT investment in the short term: the Big Bang approach and the Phase approach. Herein, we study the two approaches as alternatives in developing the Next Generation System, and derive the factors that are to be considered in the evaluation of the two alternatives for financial businesses. The set of standards for the choice between the two models are grouped into categories that constitute performance evaluation for IT - Cost, Performance and Risk. We drill down further into each category to second and third subordinate levels to derive detailed selection criteria. Based on the criteria drawn from the study, we conduct a survey with information system planners, IT managers and specialists at financial companies who are currently planning, developing or have completed a Next Generation System. Survey results are analyzed using the AHP methodology to compare and understand the different approach in the implementation of NGS for financial business.

A nuclear power plant requires a huge amount of initial investment and long construction lead time. As we expect that there may exist a relationship between investment and construction lead time, a number of researchers have reported that nearly a half of investments is incurred due to time factors such as the time value of money and inflation or escalation rates. Therefore, we investigated in this paper a relationship between the initial investment and the construction lead time of a nuclear power plant construction, and proposed a method for a trade-off analysis between the annual equivalent worth and the investment alternatives to reduce the construction lead time. Finally, we presented a real case to numerically explain the steps of the method presented in this paper.

To decide a reasonable investment priority of public enterprises, it is required to have an efficient evaluation standard. However, without having a standard, a budget for those enterprises has been allocated. In this research, for the efficient and reasonable budget allocation, it is discussed how to decide investment priority of information and communication enterprises of the government. In order to examine possible alternatives of the investment priority of information and communication enterprises of the government, seventeen enterprises were chosen from the enterprises of Ministry of Information and Communication. Public benefit, economic benefit, technology, politics, and step-up increase of budget were set up as evaluation standards and 16 specific standards were set up as subordinates. A hierarchical decision model was designed and analyzed by using AHP.
