국내 건설프로젝트는 공정관리와 원가관리의 이원적 관리체계를 가지고 있으며, 공정관리는 아직 그 체계가 미흡하고 상대적으로 관리의 중요도가 낮게 평가되고 있는 현실이다. 현재의 원가위주의 관리체계로는 프로젝트 진행과정상의 수행성과를 정확히 파악하기 어려우며, 이에 따라 공기지연, 공사비초과, 생산성저하 둥의 문제가 야기되고 있다. 따라서 프로젝트를 계획된 기간과 비용안에 효율적으로 완성하기 위해서는 비용과 일정의 통합관리를 통한 정확한 실적관리기법의 도입이 요구된다. 이에 본 연구에서는 실공정을 중심으로 한 실적관리를 통해 프로젝트의 성과를 정확히 파악하여 성공적 프로젝트 수행을 위한 방안으로 비용과 일정의 통합관리를 통한 실적관리 모델을 제시하였다.

In the past two decades, due to the rapid fluctuations in the oil supply and demand in Northeast Asia as well as a surge in oil prices in the early 2000s, Korea has been developing the Northeast Asia Oil Hub project as a national project. This project was promoted based on the policy consideration that the nation's energy security and regional development can be promoted by establishing an oil hub in Northeast Asia that can eventually replace Singapore as East Asia's oil logistics hub. Following the construction of a large-scale oil storage facility in Yeosu in 2013, the main project in Ulsan has suffered many difficulties due to environmental changes such as the supply and demand of oil and political factors. The survey, which investigated the performance, problems, and prospects of the oil hub project, illustrates that scores of all sectors are of average level. In terms of performance and prospects, policies such as facility investment, law, and system improvement were determined to be rather high while operational areas such as value-added activities, profitability, and marketing activities were perceived as having more serious problems by respondents. In conclusion, despite the strong potential of Korea's oil hub based on its geographical location, facilities, and oil product capacity, there are problems related to policies, institutions, and investment. In the future, the oil hub business should be reviewed by considering environmental factors, and a drastic improvement plan for attracting foreign investors and oil traders should be established.

Defense R&D is an essential investment for the national security. Recently our nation has also begun to initiate a number of defense R&D projects. As a lot of fund and resources are allocated to these projects, we need to identify which projects to initiate and then how to manage these projects well. Though there have been a number of studies on R&D projects in commercial sector, there are only a few studies in defense R&D sector. Moreover, these existing defense R&D studies mainly deal with the former issues, which are occurring at the stage of project planing. We are more concerned with project management issues, such as how to manage projects that had already been evaluated to undertake at the planning stage. Specifically our study aims to identify project management factors leading to the success of defense R&D projects. Results of the empirical analysis indicate that management support, user-driven requirements management, and project planning capability are key elements for project performance.

The accuracy of cost estimation at an early stage in school building project is one of the critical factors for successful completion. So various of techniques are developed to predict the construction cost accurately and expeditely. Among the techniques, Support Vector Machine(SVM) has an excellent ability for generalization performance. Therefore, the purpose of this study is to construct the prediction model for construction cost of educational building project using support vector machine technique. And to verify the accuracy of prediction model for construction cost. The performance data used in this study are 217 school building project cost which have been completed from 2004 to 2007 in Gyeonggi-Do, Korea. The result shows that average error rate was 7.48% for SVM prediction model. So using SVM model on predicting construction cost of educational building project will be a considerably effective way at the early project stage.

Traditional project progress method(PPM) has been used for Korean defense research and development project management for the last 20 years. However, it is difficult to intuitively understand the performance in terms of the project schedule, because the PPM does not provide the function of managing and forecasting project schedule. Therefore, this paper proposes new schedule managing and forecasting function for the PPM using earned schedule management concept. We verify the effectiveness of the proposed functions through several defense projects and prove that it is possible to reinforce the schedule management function of the PPM.

It is commonly recognized to need performance management for successful construction project. PPC measurement of Last Planner System is one of construction project measurement method. PPC measurement is quantitatively assessment to go through construction, and that is not completely to be trusted when compare a project with another or an individual case work with another in same project. According to, purpose of this study is comparison indicator establishment that compare project with another or an individual case work with another it is not use PPC measurement for quantitatively assessment to go through construction. The procedure of this study is derive of the point at issue of existing PPC measurement for a aim PPC measurement in this study expenditure and select weight about that and it is applied to actually construction.

In the highway engineering, the performance, quantity and status of machines available for the project have direct impact on the project time. For instance, the status of machines, such as working or in trouble, have great influence on the activity execution. Therefore, while scheduling the project, the project manager always increases the spare machines or prolong the activity time to avoid delaying the project time when some of the machines are in trouble in construction site. However, how many are the spare machines and how long are the prolonged activity time, which are estimated subjectively by the manager. This subjective estimation has been criticized for systematically overestimating or underestimating quantity of the machines and the activity time. In the paper, we propose and prototype a model to simulate the status of the machines in construction site, and then to evaluate the schedule feasibility considering the performance, quantity and statues of the machines involved.

Line of Balance (LOB) method is suitable to schedule construction projects composed of repetitive activities. Since existing LOB based repetitive project scheduling methods are deterministic, they do not lend themselves to handle uncertainties involved in repetitive construction process. Indeed, existing LOB scheduling dose not handle variability of project performance indicators. In order to bridge the gap between reality and estimation, this study provides a stochastic LOB based scheduling method that allows schedulers for effectively dealing with the uncertainties of a construction project performance. The proposed method retrieves an appropriate probability distribution function (PDF) concerning project completion times, and determines favorable start times of activities. A case study is demonstrated to verify and validate the capability of the proposed method in a repetitive construction project planning.

본 연구는 정부의 대표적인 상용화 기술혁신정책인 산업기술개발사업의 성과에 영향을 미치는 요인을 분석함으로써 관련 정책결정자에게 정책적인 시사점을 주는데 목적이 있다. 이를 위해 2003년부터 2007년간 종료된 산업기술개발사업을 대상으로 정부가 중요하게 고려하는 정책요인별로 가설을 형성하였다. 사업을 수행한 주관기관의 유형(대기업, 중소기업, 벤처기업, 연구소, 대학)에 따라 R&D성과에 차이가 있는지, 산학연간의 협력 개발이 단독 개발에 비해 R&D성과가 나은지, 과제 참여기관 수와 R&D성과의 관계, 과제 총금액의 크기와 R&D성과의 관계, 과제 총금액에서 차지하는 민간 총투자금의 비중과 R&D성과의 관계 등을 검증하고 있다. R&D성과는 산업기술개발사업의 제1차적 성과물인 특허등록건수와 논문게재건수로 측정하였다. 포아송 회귀분석 결과, 기업이나 연구소에 비해 대학이 특허 및 논문 차원의 R&D성과가 높은 것으로 나타났으며, 벤처기업의 특허 성과는 중소기업의 특허성과에 비해 높은 것으로 나타났다. 산학연의 협력개발은 단독개발에 비해 대체적으로 R&D성과가 높고, 과제 총금액이 클수록 R&D성과가 높으며, 민간 총 투자금의 비중이 높을수록 대체적으로 R&D성과가 높은 것으로 나타났다. 과제 참여기관의 수와 R&D성과간의 역U자형 관계 가설은 지지되지 않았다.

A severe problem in VE study of a project is to reduce value due to loss of performance, caused by focusing on cost reduction. Also a lack of understanding performance concept, no trial VE workshop as well as cost saving-based policy have not satisfied customer needs. A efficient VE job plan for especially large scale railroad construction project is proposed in this study. This study developed a more objective performance evaluation system for value engineering study of mega projects and suggested a systematic process of performance quantitative analysis for value improvement. The proposed performance measurement method would be very useful for better communication and consensus between decision makers and VE team.
