The purpose of this study is to identify the risk factors, analyze the risk factors and make a risk check list of survey in road construction. Generally. the risk management is consisted of 3 steps: risk identification, Risk analysis, Risk hedge. This study is focused on the identification of risk and analysis of risk. To identify the risk factors of survey, we used the specifications of road construction, law of survey, and check list of road construction. This study provides the risk check list of survey for road construction. This research was undertaken to analyze risk factors being determine by the FGI(Focus Group Interview) method with survey specialists.

정보시스템 개발 프로젝트는 그 속성상 고객, 팀원, 환경등의 요인으로 유일성을 가지고 있어 개발 과정을 체계적으로 관리하기가 매우 힘들고 프로젝트의 대형화, 전문화, 복잡화, 장기화에 따라 더 많은 리스크(risk)요인과 불확실(uncertainty)요인이 존재한다. 따라서 본 연구는 정보시스템 개발 프로젝트의 실패에 영향을 미치는 리스크요인을 도출하고, 리스크요인들의 중요도(위험도)를 측정하기 위한 AHP(Analytical Hierarchy Process) 모델을 제시함으로써 프로젝트 수행 시에 발생할 수 있는 리스크를 관리하고, 실질적인 의사결정도구를 제공하고자 한다.

Recently construction environment is being professionalized. oversized and diversified. Due to fluctuation of construction environment, the demand for the project of steel structure is ieased gradually and steel construction is needed the efficient quality management. The construction of steel structure which required a variety of sub-contractors, the progress of works and technologies are comprehensive of various risks and uncertain factors. But currently the construction of steel structure is conducted the risk management by perception and experience of constructors. Therefore, the analyzing factors of the risk and establishing the device are able to manage the quality management efficiently. In this study, we have conducted the interview of experts, polls and through the Analysis Hierarchy Process (AHP) for the scientific and systematic risk management. This paper will propose a plan for systematization of the construction of the steel structure.

소프트웨어 테스팅에서 리스크 기반 테스팅은 리스크 식별, 리스크 분석, 리스크 계획, 리스크 추적의 4 단계로 전개되며, 특히 마지막 단계인 리스크 추적 단계에서는 식별된 리스크가 테스팅 진행과정을 거치면서 어느 정도 완화되었는지를 확인하고 현재의 리스크 완화 정도에 따라 적절하게 대응하는지를 모니터링 해야 하는 중요한 단계이다. 하지만 리스크 추적 단계에서 필요한 리스크 완화 수치가 정의되지 않아 사용자들은 테스트 실행율 또는 결함 해결율 등을 리스크 완화 수치의 대안으로 사용하고 있다. 본 논문에서는 리스크 추적 단계에서 사용할 수 있는, 리스크의 완화 정도를 수치화한 "리스크 해결 지수"의 산출 과정을 수식과 함께 제시하고 그 의미를 설명하였다. 그리고 예시를 통해 리스크 수치화에 대한 이해를 돕고, 리스크 수치화 관련 차트를 몇 가지 제시하여 실무에의 응용 통찰력을 제공한다. 리스크를 수치화한 "리스크 지수"는 테스팅 조직의 의사결정에 활용할 수 있는 객관적이고 설득력있는 정보로서 프로젝트 전반에 걸쳐 그 활용 가치가 높다.

복잡하고 숨가쁘게 변화하는 경영환경 속에서 리스크 관리 (Risk Management)는 기업경영상의 위험을 관리한다는 점에서 매우 중요한 과제로 대두되고 있다. 특히 PL법과 같은 새로운 법이 시행될 때마다, 기업은 새로운 재정적인 어려움에 직면하게 된다. 이 연구에서는 리스크 관리에 관한 국가규격들을 비교 검토하고, 특히 제조물 책임법의 시행에 따라 새롭게 등장하는 PL 리스크의 대응방안에 관하여 자금조달이라는 측면에서 고찰한다.(중략)

In recent years, the reduction of international award and project loss by Korean contractors have become a big issue not only in industry but also in academic fields. However, many researches have not focused on small and medium subcontractors but on the large contractors, even though the number of international project by small and medium companies is more than by large companies. Therefore, this study focuses on analyzing the predicted risk before bid and the actual risk after award in international subcontracting projects. In addition, it provides the difference between project performances according to the contract types and the project profitability. This study is expected to give more informed risk knowledge to small and medium subcontractors, which enables them to pay attention to managing risk for better project performances.

With Public-private partnership PF (project financing) deals saw explosive increase in quantity since its introduction to Korea in 2001, but, met with severe recession in the fallouts of the financial crisis that hit the global economy in 2008. This study intends to identify the risk factors corresponding to issues of public-private partnership projects financing structure and classify and analyze them by project phase. Outcomes of this research are expected to help recognize risk factors in each project phase during project planning and develop risk control and mitigation strategy during project implementation.

This study presents a risk management methodology using fuzzy theory for early construction stage and is focused on risk identification and risk analysis. This study identifies various risk factors associated with activities clearly construction stage, then establishes the Risk Breakdown Structure(RBS) by classifying the risks into the three groups; Common risks, risks for Earth works, and risks for Foundation works. The risk analysis method presented in this study is based on the RBS that has two levels such as upper level and lower level. The risk exposure of lower level risk factors is assessed by fuzzy inference. The weight of risks is estimated by fuzzy measure. Then, the estimated risk exposures and weights are aggregated to assess the risk exposure of upper level risks by Choquet fuzzy integral. The risk exposure of upper level risks determine the priority of risk factors in view of risk management. This study performs case study to validate the proposed method. The result of case study shows that the methodology suggested in this thesis would be utilized well in evaluating risk exposure.

The construction environment has the trend of oversizing and professionalizing, the increase of the construction period, and the risk factors and the uncertain factors which are important in the construction bid. The misunderstanding and the lack of knowledge of the subcontractor result in the decrease of the profit or the deficit. In conclusion, these are supposed to give the financial burden to the subcontractor. So, it is very important to predict the construction preparation cost calculation by the risk factors in the bidding stage and to calculate the bid unit cost considering the target profit of the subcontractor in the process of the mutual agreement and performance of the contract. In these points of view, this study analyzes how the importance of the risks influencing the bidding cost calculation affect the construction cost, and this analysis can be used as the basic data to establish the suitable bid strategy of the subcontractor.

The insufficient management o( the risk of preconstruction phase causes the risk of construction phase so it makes bad effects such as the extension of construction time and raising of cost. Therefore, the management of the risk of preconstruction phase is being considered as an important element of success of project and the competitive power of construction companies. This study Is to suggest solution methods for each progress after examining reasons of the risk for the management of the risk of preconstruction phase 1'he progress is limited as earth work, RC work, steel work and curtain wall work. Through the introduction of Knowledge Management system, work flow is made by specialist of each part. The reasons of the risk of progress are chosen through the analysis of work flow and I suggest detailed solutions such as person in charge, the starting point of progress and the information of requirements according to the grade of importance about elements of the risk
