Some issues which should be considered in an R&D project selection problem are as follows: First, quantitative analysis on the efficiencies of R&D projects is required to guarantee objective validity in the evaluation of the projects. For this reason, the methodology for selecting R&D projects should be based on mathematical models that perform quantitative analysis. Second, in general there are ordinal factors like Likert-scale in the data for evaluating R&D projects. Previous researches, however, couldn't suggest explicit methods incorporating these ordinal factors into models. Third, for the R&D project selection problems with limited resources like budget, it is necessary to decide the perfect ranking of the all projects. This paper develops a mathematical model that can be applicable to the problems of selecting R&D projects with the previous features. In this paper, we improve the original DEA model for evaluating efficiency to incorporate ordinal factors and suggest a new model which can decide the perfect ranking of all projects by merging the improved DEA model and AHP method. Furthermore a web-based R&D project selection system using the DEA/AHP model suggested in this paper is developed and illustrated.

IT프로젝트를 수행하는 기업은 정해진 예산범위 내에서 투자계획을 수립하고 실행하게 된다. 이 과정에서 IT프로젝트를 효과적, 효율적으로 선정하는 문제는 기업경쟁력과 직결되는 중요한 요소이다. 그동안 IT프로젝트의 선정을 위한 다양한 모형이 개발되었으나 예산제약을 고려한 효과적 프로젝트 선정에 대한 연구는 보고되지 않고 있다. 본 연구에서는 예산 제약을 고려하여 효과적으로 IT프로젝트를 선정하는 기법을 제시하였다. 본 연구에서 제안한 모델(AHP-K)에서는 AHP(Analytic Hierarchy Process : 계층분석법) 기법을 적용하여 평가 항목의 가중치와 프로젝트 후보군의 가중치를 산정한 후 배낭문제(Knapsack Problem)를 적용하여 예산 범위 내에서 프로젝트 효용을 최대화하는 선정안을 도출한다. 실제 적용단계에서 고려하는 대안이 많거나 신규대안이 추가되는 경우 쌍대비교의 수행이 어려운 점을 감안하여 대안 비교 단계에서 절대평가법을 적용하였다. 본 연구에서는 제시된 모델을 실제 사례에 적용하여 기존 AHP 모형과 비교 분석함으로써 효과성을 검증하였다.

Digital Multimedia Broadcasting (DMB) and Internet Protocol Television (IPTV) are now in commercial service, tearing down the traditional boundaries between the telecommunications and broadcasting sectors. These latest developments also hold important implications for research projects in related areas. Both telecommunications and broadcasting being fields with a strong service orientation, market demand should be the primary consideration when selecting research and development (R&D) projects in these areas. This study presents a process for selecting converged telecommunications-broadcasting technology development projects from a demand-oriented perspective, using criteria that are based on projected future demand characteristics. Aimed at increasing the efficiency of the R&D project selection process in telecommunications and broadcasting convergence, this study can point out new directions in R&D management in this field.

A contractor or a main contractor is a company with full capacity to construct all project's works for the owner. A subcontractor is an organization that works with the main contractor to execute and complete work packages for the project. Selecting an effective subcontractor will help the efficiency and success of any projects in the construction industry. Therefore, this study identified subcontractor evaluation factors in Vietnam by collecting questionnaire survey data from engineers and staffs in the construction industry project environment. An exploratory factor analysis (EFA) was then performed to identify the critical factors when evaluating and selecting the subcontractor in construction projects. Moreover, when considering the impact level in terms of the average value, the research results showed that the most critical concern was the subcontractor's reputation. Furthermore, the top five factors affecting the sub-contractor evaluation and selection are (i) reputation, (ii) price, (iii) construction techniques, (iv) ability to implement projects according to commitments, and (v) subcontractor competence (the team of workers, technician staff, engineers with full capacity according to regulations). These research results provide an overall perspective that will help main contractors develop suitable subcontractors' evaluation and selection factors in their projects in the construction industry.

본 연구는 정부와 전문기관간에 위임-대리인관계가 대리인문제를 발생시키고 연구관리전문기관의 효율성에 영향을 미칠 수 있다는 가정 하에, 법적위탁이 아닌 계약에 의한 위탁사업은 사업수탁에 대한 불확실성과 외부영향에 의한 대리인 비용 발생으로 법적 위탁사업 보다 효율성이 낮을 것이라는 가설을 검증하고 사업별 효율성에 미치는 영향요인들을 분석하고자 한다. 이를 위해 정부와 전문기관간의 세부사업별 사업위탁방식(더미변수)과 사업관리비 비율간의 관계를 분석하기 위해 사업방식(Top-down/bottom-up), 사업규모(예산, 과제수), 기관운영경비 편성비중, 기관의 수권예산대비 출연금 비율 등을 통제변수로 사용하였다. 분석결과에 따르면, 사업관리 효율성과 정부와의 사업위임방식(법적위임)간의 양의 상관성이 확인되었으며, 전문기관의 안정성과 독립성을 반영할 수 있는 법적지위 및 예산 구조 관점에서의 시사점이 도출되었다. 본 연구의 정책적 함의로서, 전문기관의 사업관리 효율성을 높이기 위해서는 법적인 안정성과 예산의 안정성이 확보되어야 하고 이를 통해, 위임자-대리인 문제에서 발생하는 도덕적 해이나, 역선택을 회피할 수도 있다는 점을 시사한다.

The present study is aimed to quantifying the uncertainty in the general circulation model (GCM) selection and its impacts on hydrology studies in the basins. For this reason, 13 GCMs was selected among the 26 GCM models of the Fifth Assessment Report (AR5) scenarios. Then, the climate data and hydrologic data with two Representative Concentration Pathways (RCPs) of the best model (INMCM4) and worst model (HadGEM2-AO) were compared to understand the uncertainty associated with GCM models. In order to project the runoff, the Precipitation-Runoff Modelling System (PRMS) was driven to simulate daily river discharge by using daily precipitation, maximum and minimum temperature as inputs of this model. For simulating the discharge, the model has been calibrated and validated for daily data. Root mean square error (RMSE) and Nash-Sutcliffe Efficiency (NSE) were applied as evaluation criteria. Then parameters of the model were applied for the periods 2011-2040, and 2070-2099 to project the future discharge the five large basins of South Korea. Then, uncertainty caused by projected temperature, precipitation and runoff changes were compared in seasonal and annual time scale for two future periods and RCPs compared to the reference period (1976-2005). The findings of this study indicated that more caution will be needed for selecting the GCMs and using the results of the climate change analysis.

국내 공공건설사업의 건설기술용역업체 선정을 위한 발주 및 입 낙찰방식을 관련법에서 다양하게 제시하고 있으나, 용역업체 선정을 위한 발주 및 입 낙찰 방식 선정 기준 및 틀이 부재한 실정이다. 아울러, 현행 건설기술 용역업체 선정에서 가격중심의 선정 방식이 주로 활용되고 있다. 이에 본 연구에서는 현행 국내 건설기술용역 발주 및 입 낙찰 방식의 실태조사를 통하여 문제점을 도출하고, 건설기술용역사업의 효과적인 성과 도출과 효율성 극대화를 위해 다양한 발주 및 입 낙찰 방식의 활용방안 및 기존 방식의 개선사항 등을 제시하였다. 이러한 개선방안을 통하여 사업의 성격에 부합한 발주 및 입 낙찰 방식의 활용이 가능한 기반을 조성하고, 기존 가격중심에서 탈피하여 기술기반의 평가요소를 반영하여 용역업체를 선정함으로써, 용역업체의 기술력 향상과 해외시장에서의 경쟁력을 강화하는데 기여 할 수 있을 것으로 판단된다.
