Recently organizations identify information security as one of essential means for gaining competitive advantage. However, they do not actively increase investment in this area because they consider spending for information security as a cost rather than an investment. This is because organizations don't have a clear understanding of information security objectives which can be achieved through investment, and they don't have criteria for alternatives which can be considered in information security investment decision-making. In this paper we propose to model the decision-making process of information security investment by the AHP (Analytic Hierarchy Process). The results will show that availability is the most important criterion for the decision of information security alternatives, and intrusion detection is the most important information security alternative. We hope that the results of this paper provide a guideline for clear decision-making in information security investment.

그간 크라우드펀딩에 대한 연구는 주로 크라우드펀딩의 도입을 위한 방안, 정책에 주로 관심을 가졌으나, 본 연구는 투자의사결정기준을 분류하고 각 요인의 중요성을 제시하여 크라우드펀딩 투자자들에게 실질적으로 도움을 줄 수 있는 연구결과를 도출해 내었다. 연구결과에 따르면 (1) 크라우드펀딩 투자자는 비즈니스 모델을 보다 객관적으로 판단하기 위한 방안으로 기업의 유형자원을 가장 중요한 기준으로 고려하고 (2) 기업의 경영능력에는 관심이 많지만, 비즈니스 모델에 대한 창의성은 크게 관심을 가지고 있지 않고 있음을 확인하였다. 이 연구결과는 크라우드펀딩이 계량적 투자기준을 통해 투자의사를 결정할 수 있고, 창의적인 비즈니스 모델에 대한 건전한 투자라는 인식이 형성될 수 있는 환경이 조성되어야만 하며, 신규기업도 창의적인 비즈니스 모델을 통해 기존기업과 건전한 경쟁을 할 수 있는 제도적 장치가 필요하다는 점을 시사한다.

A capital investment problem is essentially one of determining whether the anticipated cash Inflows from a proposed project are sufficiently attractive to invest funds in the project. The net present value(NPV) criterion and internal rate of return(IRR) criterion are widely used as means of making investment decisions. A positive NPV means the equivalent worth of the inflows is greater than the equivalent worth of outflows, so, the project makes profit. Business people are familiar with rates of return because they all borrow money to finance ventures, even If the money they borrow is their own. Thus they are apt to use the IRR in preference to the NPV. The IRR can be defined as the discount rate that causes the net present value of a cash flow to equal zero. Why the project are accepted if the project's IRR is greater than the investor's minimum attractive rate of return. Against the NPV, the definition cannot distinctly explain the concept of the IRR as decision criterion. We present a new definition of the IRR as the ratio of profit on the invested capital.

최근 SNS 이용이 활성화됨에 따라 SNS 제공환경에서의 정보보호에 대한 관심이 증가하고 있다. 하지만 SNS 산업 환경의 급격한 성장으로 인한 가입자 유치 위주의 투자 선행과 서비스 제공자 측면에서의 SNS 정보보호 투자 효과에 대한 확신 부족, 그리고 SNS에서의 정보보호 중요위협요인에 대한 분석체계 부재로 인해 아직까지 SNS 제공환경에서의 정보보호에 대한 투자가 미흡한 실정이다. 본 논문에서는 AHP를 이용한 SNS 제공환경에서 정보보호 중요위협요인 분석을 통해 정보보호 투자 결정 기준 도출에 대한 연구를 수행하였다. 본 연구를 통해, '서비스 이미지'가 정보보호 평가기준에서 가장 중요한 항목으로 도출되었으며, '개인 프로파일 위조 및 명예훼손'과 '산업 스파이'가 중요한 SNS 정보보호 위협요인인 것으로 나타났다.

Since sewer rehabilitation program requires long construction period and enormous capital investment, determination of rehabilitation priorities is important with systematic planning considering appropriate evaluation parameters. In this research, we applied PROMETHEE(Preference Ranking Organization METHod for Evaluations) known as very objective and scientific multi-criteria decision-making analysis, using the weights determined by AHP(Analytic Hierarchy Process) for the selected sewer evaluation items to calculate the rehabilitation priorities for each sewer sub-catchment in basin Gusan 1 of Seoul. Preference functions and preference thresholds were estimated for each criterion of ratio of lack of hydraulic capacity of sewers, defect ratio, ratio of sewers with velocity less than its minimum criteria, and density of sewers in the sub-catchment. As a result, it was found that region d had the first priority among four sub-catchments. For each and every sewer located in region d, we could also rank sewers to be rehabilitated urgently.

본 연구는 산업보안활동을 수행함에 있어, 운영 수준의 관리대책에 대한 전략적 우선순위 결정을 통해 합리적인 보안투자 의사결정 지원을 목적으로 하였다. 이를 위해 산업보안전문가들을 대상으로 AHP 설문조사를 시행, 분석하여 산업보안 관리대책들의 중요도와 우선순위를 결정하였다. 상위기준 비교평가에서는 'ICT서비스 사용관리'가 가장 높은 가중치(0.54)를 보였다. 하위기준은 중요도 순으로 3개 그룹으로 구분할 수 있었다. 민감도 분석결과, 'ICT시스템/통신망 접근통제'의 가중치를 2배 높이면 그 하위기준인 '운영체제 접근통제', '애플리케이션 접근통제', '유무선 네트워크 접근통제'의 전체 순위가 상위권으로 진입하였다. '물리/환경적 보안'의 가중치를 2배 높이면 그 하위기준인 '보호구역 설정 및 출입/접근통제'와 '업무설비방재/대테러 보호 배치'는 전체 순위가 상위권으로, '전원 등 유틸리티 상시 확보'는 중위권으로 상승함을 확인할 수 있었다.

In this paper, we investigated impact factors by brainstorming and survey research and calculated the weights of them using the Analytic Hierarchy Process(AHP) method in order to evaluate alternatives for supplying Liquefied Natural Gas(LNG). AHP is a useful method for evaluating multi-criteria decision making problems. We selected 3 criteria and 9 sub-criteria. According to the result in this study, the most important sub-criterion is the Government's Policy, and the second is the Province's Policy. The other side, the lowest important sub-criterion is the Investment Cost. This study may provide basic data to select the optimal alternative for supplying LNG.

The IRR(internal rate of return) is often used by investors for the evaluation of engineering projects. Unfortunately, it has serial flaws: (1) multiple real-valued IRRs may arise; (2) complex-valued IRRs may arise; (3) the IRR is, in special cases, incompatible with the net present value (NPV) in accept/reject decisions. The efforts of management scientists and economists in providing a reliable project rate of return have generated over the decades an immense amount of contributions aiming to solve these shortcomings. Especially, multiple internal rate of returns (IRRs) have a fatal flaw when we decide to accep it or not. To solve it, some researchers came up with external rate of returns (ERRs) such as ARR (Average Rate of Return) or MIRR (MIRR, Modified Internal Rate of Return). ARR or MIRR. will also always yield the same decision for a engineering project consistent with the NPV criterion. The ERRs are to modify the procedure for computing the rate of return by making explicit and consistent assumptions about the interest rate at which intermediate receipts from projects may be invested. This reinvestment could be either in other projects or in the outside market. However, when we use traditional ERRs, a volume of capital investment is still unclear. Alternatively, the productive rate of return (PRR) can settle these problems. Generally, a rate of return is a profit on an investment over a period of time, expressed as a proportion of the original investment. The time period is typically the life of a project. The PRR is based on the full life of the engineering project. but has been annualised to project one year. And the PRR uses the effective investment instead of the original investment. This method requires that the cash flow of an engineering project must be separated into 'investment' and 'loss' to calculate the PRR value. In this paper, we proposed a tabulated form for easy calculation of the PRR by modifing the profit and loss statement, and the cash flow statement.

Recently, new financial services related to FinTech has gained attention more and more. Online P2P financial services transactions such as FinTech require careful examination of the constituents of information systems as an investment is made based on the information presented on the online platform without direct face-to-face contact. The purpose of this study is to find out the success factors of online P2P Lending service among FinTech. To serve the purpose, we build IS (information system) success model, and then use Kano model and fuzzy analytic hierarchy process (Fuzzy-AHP) to find out factors for the success of online P2P Lending service. In particular, this study uses Kano model to classify information system satisfaction factors and to calculate the satisfaction coefficient. The Kano model, however, has a drawback of evaluating single criterion. Therefore, we use multi-criteria decision-making technique such as Fuzzy-AHP to derive the relative importance of the factors. The analysis results show different results depending on the analysis technique. In the Kano model, most of the information system factors are a one-dimensional quality attribute. The satisfaction coefficient is highest for personalized service, followed by the responsiveness of service, ease of using a system, understanding of information, usefulness of information' reliability. The service reliability is the highest in dissatisfaction coefficient, followed by system security, service responsiveness, system stability, and personalized service. The results of the Fuzzy-AHP analysis shows that the usefulness of information quality, the personalization of service quality, and the security of system quality are the significant factors and the stability of system quality was a secondary factor.
