Many organizations have been outsourcing not only simple tasks but Information Systems and business processes rapidly. IT outsourcing is considered as a critical strategy of businesses these days. Anyhow, many companies still have IT solution problems even though they have been outsourcing their IT department or functions. Moreover, many companies have difficulties when it comes to the selection a proper IT outsourcing service vendor. This study focused on evaluation methodology for small and medium sized organizational selection of IT outsourcing provider. This study's results is a presentation of an evaluation methodology using the AHP weighted value of the factors and the factors' variables. Small and medium sized organizational managers can refer to this study's result as an evaluation index and methodology at the beginning of their IT outsourcing project or for changing their vendors.

본 연구에서는 제품 개발과 관련된 시장 환경 요소들을 고려하여 신속한 제품 개발에 관한 의사 결정을 할 수 있는 AHP 모형을 제안하고, 정량화 된 데이터를 이용한 AHP 의사결정 프로세스를 구축하고자 하였다. AHP 모형의 경우 전문가 집단(연구원 집단, 엔지니어 집단, 판매자 집단)별로 의사결정의 차이점을 보여 줌으로서 각각의 시장 상황에 맞는 의사결정을 경영자가 효율적으로 판단할 수 있도록 제시하였으며, 신제품 디자인 선정의 간단한 프로세스를 제시하여 반복적인 생산자의 의사 결정을 합리적이고 신속하게 할 수 있는 방법론을 제시하였다. 프로세스에서는 하위 의사결정 단계에서 가능한 데이터의 정량화를 통해 쌍별 비교 행렬을 만듦으로써, AMP기법의 정확성을 높이고 모델의 민감도 분석이 가능하게 하였다.

This paper aims to construct an effective decision making model on selection of product design in product development using fuzzy AHP technique. It is expected that this paper contributes to enhancement of company's market competitiveness by shortening the lead time to develop a new product and minimize initial investment. The proposed model using fuzzy AHP enables quick decision making by integrating and analyzing all customer requirements related to a product. In addition, it can deal with vagueness and uncertainty of decision making process using fuzzy set theory. Decision making processes for evaluating the best selection of product design are also constructed to describe the exact concept of development. A tennis racket is shown as an example. The proposed model is expected to be applied in various fields of managerial decision making processes as well as of product development process.

본 연구에서는 SNS 매체 평가를 위해 적용 가능한 품질의 측정요인들을 문헌고찰하고, 평가방법론으로 AHP 기법을 적용하여 SNS 매체를 평가할 수 있는 방안을 제시하고자 하였다. 선행연구에 의거하여 SNS 품질요인을 시스템품질, 정보품질, 인터페이스품질, 서비스품질 등으로 분류하였고, AHP 기법을 적용하여 품질요인별 중요도를 실증 분석하였다. 측정결과로서 서비스품질이 상대적으로 가장 주요한 요인으로 도출되었으며, 정보품질, 시스템품질, 인터페이스품질 등의 순으로 중요도가 높은 것으로 나타났다.

Quality assurance (QA) for nuclear R&D project is very concerned about the poor economy due to the improper selection of QA requirements. This paper proposes a new methodology for determining the relative importance weights of QA requirements considering the attributes of nuclear R&D project. QFD (Quality Function Deployment) is used as a conceptual framework and fuzzy number is introduced to capture the vagueness uncertainty existing in human judgement. Also we use a confidence attitude of decision-maker in order to improve the reliability of extracted attribute level of R&D project. Case study on a nuclear R&D project and scenario analysis are carried out to verify the usefulness and effectiveness of proposed methodology.

Significant research has been devoted to the consistency index of the Analytic Hierarchy Process(AHP) from several perspectives. Critics of the consistency index in AHP state that the critical value of consistency index depends on an average of the random index based simulation study using a 9 scale comparison matrix. We found that the distribution of the consistency index followed the skew distribution according to the dimension of the comparison matrix based on a simulation study with a 9 scale comparison matrix. From the simulation study, we suggest a consistency index quantile table to assist the decision-making process in AHP; in addition, we can approximate the distribution of the consistency index to the gamma distribution under the limited assumptions.

There are rule-based learning method and statistic based learning method and so on which represent learning method for hierarchy relation between domain term. In this paper, we propose to leveling and similarity measure using the extended AHP of fuzzy term in Information system. In the proposed method, we extract fuzzy term in document and categorize ontology structure about it and level priority of fuzzy term using the extended AHP for specificity of fuzzy term. the extended AHP integrates multiple decision-maker for weighted value and relative importance of fuzzy term. and compute semantic similarity of fuzzy term using min operation of fuzzy set, dice's coefficient and Min+dice's coefficient method. and determine final alternative fuzzy term. after that compare with three similarity measure. we can see the fact that the proposed method is more definite than classification performance of the conventional methods and will apply in Natural language processing field.

The current global water market has been reshaped with a few multinational water companies, water-specialized companies, and other non-construction companies such as manufacturing and financial companies. Each has different business objectives along with the value chain of water industry. In this context, a SWOT-ANP model is proposed to prioritize strategic alternatives for a non-construction company in Korea and the result is validated through a comparison with the AHP model and real business strategies of the company examined from the recent news reports. The validation was confirmed that the company's strategies are very much similar to the priority list and the rankings of the strategic alternatives are identical with those from AHP model, while the weights are slightly changed from the weights in AHP result.

Countries around the world are making active efforts to reduce greenhouse gas emissions. Korea is also pursuing a policy of abolishing aging coal power and converting it to LNG power generation. However, in Korea, gas turbine manufacturing technology has not been localized, so all of it is imported and installed from overseas manufacturers. Therefore, this paper examines the domestic and foreign environment of the gas turbine power generation industry and proposes a strategy to develop and expand the supply of Korean gas turbine technology by applying the PEST-SWOT-AHP methodology. As a result of the research, the strategy to develop and expand the supply of Korean gas turbine technology can be summarized as 1) strengthening the role of power generation public enterprises to develop and promote commercialization of gas turbine technology, 2) expanding the proportion of LNG power generation to reduce greenhouse gases, 3) the government's active efforts to create an ecosystem for the gas turbine industry, and 4) forming a public consensus on the construction of LNG power plants.
