This study suggests a reasonable method for visualizing risk management level by risk weight linked with 4D model. This study defines risk management procedures as preparation, identification, analysis, response and management to manage potential risks in the construction project. The modules for computerizing in this system consist of planning, construction, application of WBS (Work Breakdown Structure) and RBS (Risk Breakdown Structure), and risk analysis. The final results include a method for visualizing risk level by each element of the project by using 4D simulation technique. It can be used as a visualized risk management tool instead of current system using numerical data.

본 논문은 재난 리스크 평가를 위한 집계구 통계자료의 활용방안에 대한 연구를 수행하였다. 인구통계자료, 주택통계자료, 전국사업체 자료는 재난취약성분석과 리스크 평가를 위한 필수 요소이다. 재난의 분석과 평가를 위하여 GIS에 구축하는 자료로는 인구의 총인구, 평균나이, 인구밀도, 노령화지수, 교육수준 등이 있다. 이 자료들을 공간정보로 구축함으로써 기존의 넓은 수준의 데이터를 활용하는 것 보다 정밀한 분석이 가능하다고 판단된다. 또한, 인구와 관련된 데이터뿐만 아니라 집계구 통계 자료는 주택의 건축년도와, 주택의 유형(다세대, 아파트, 연립, 영업용건물주택의 정보를 가지고 있다. 이는 건물의 경제적 평가를 위한 자료로 활용될 것이다. 또한 선정된 지역의 사업체를 분류하여 각 폴리곤의 주요 사업체를 조사하여 공간정보를 구축함. 구축된 공간정보는 리스크 평가를 위한 자료로서 활용될 수 있다 판단된다.

기존의 리스크기반 테스팅은 조직, 프로젝트, 제품에만 초점이 맞추어져 있어 소프트웨어 개발에 관련된 리스크 활동은 잘 고려되지 않는다. 본 논문에서는 소트프웨어 개발에 리스크를 적용하고자 유스케이스 기반 리스크 위험도 측정과 우선순위화를 제안한다. 제안한 리스크 위험도 측정방법은 GoRE의 Goal 중요도 매트릭스를 리스크 결정 매트릭스로 확장하고 이를 이용하여 리스크의 위험도를 우선 순위화에 적용한 것이다. 확장한 리스크 결정 매트릭스는 유스 케이스와 요구사항의 연관관계를 파악한 후 고객 중요도를 계산하여 리스크 위험도를 측정하는 방법이다. 이를 통해 소프트웨어 개발 전 리스크 요구사항 고려로 시스템 구축에 도움이 되고자 한다.

Considering about construction projects characteristics, there Is an existing uncertainty which causes inaccuracy or invalidity under decision making situation. Therefore, cost risk analysis of numerous construction projects are Inclined to depend on expert's experiences and subjective judgements. In Korean domestic construction works, however, there is no reasonable method or process for applying subjective elements. Only probabilistic analysis using objective calculation are being used now. This research suggests a cost risk analysis method to analyze quantitatively Cost Impact by risk, and it appraises expert's subjective elements for the purpose of enhancing validity of cost estimation. Moreover, a new cost risk analysis method is introduced for providing convenient user interface in practical business.

In recent years, Korean engineering companies are actively entering into the international business. Although international engineering project is known to have lower risk rather that EPC construction project, Korean engineering companies' international sales profit is not as good. Therefore, this study analyzes the risks that are predicted before bid and actually occurred after award. In addition, this study shows the difference of risk depending on lump sum contract and cost reimburse contract. Finally, this study analyzes the difference of risk according to civil engineering and building engineering. This study provides industry to analyze risk more practically and helps academics to focus on risk to be studied more in the future.

본 연구는 벤처캐피탈의 투자심사단계 및 투자 이후 사후관리단계에서의 리스크 관리·활용과 투자성과 사이의 관계를 살펴보았다. 즉, 투자심사단계에서는 투자대상기업을 발굴한 벤처캐피탈의 리스크 분석 및 대응방안의 활용수준과 투자성과와의 관계를 규명하였고, 사후관리단계에서는 리스크 관리를 위한 모니터링 활동과 투자성과와의 관계를 규명하였다. 본 연구에서는, 첫째, 투자심사 단계에서의 경영리스크 및 재무·법률 리스크 분석 및 활용 수준이 정량적인 투자성과, 특히, 특허 등록수에 긍정적인 영향을 미치는 것으로 나타났다. 둘째, 벤처캐피탈의 주요 역할인 투자 이후의 모니터링에 대하여는, 주관적 투자 만족도에 긍정적인 영향을 미치는 것으로 나타났다. 본 연구를 통하여 투자대상기업을 발굴하여 리스크 관리 중심으로 투자를 심사·집행하고, 투자 이후 리스크 관리 중심으로 투자기업의 가치를 증대하기 위하여는 벤처캐피탈리스트의 역할이 특히 중요하다는 것을 알 수 있었다. 투자기업이 보유한 자원·역량에 한계가 있다는 점을 고려할 때, 벤처캐피탈의 역량이 투자기업에 지원되는 것은 해당 기업이 지속적으로 성장하기 위한 바탕이 될 것이다.

As an increasing demand for rapid railway transportation, the construction of sidetrack is inevitable to operate local and express trains simultaneously. However, the current technologies for the sidetrack construction method require a long construction period by interrupting the operation of the existing subway line, as well as cause a huge economic loss. Thus, it is necessary to study the sidetrack construction method under the special situation that the subway is in operation and to analyze the risk of the existing tunnel enlargement process for the sidetrack construction. Therefore, in this paper, the Government Complex Gwacheon station on Subway Line 4 was considered as a target station for the virtual sidetrack construction and the optimal sidetrack construction plan was derived. Subsequently, the application of risk management process was carried out in the order of identifying risk, risk response planning, performing a risk analysis, risk monitoring and control for potential risk events during the construction of sidetrack under the subway operation. A total of eight potential risk events and risk mitigation methods were selected, and a risk assessment matrix was established using the five-step risk probability and impact level criteria to perform the risk assessment including residual risks. Based on the results of the risk assessment, the risk grade and the reduction effect of each risk mitigation method were confirmed.

Many construction developers have tried to develop the international PPP (Public-Private Partnership) projects but frequently failed to gain loan investor approval from loan investor. Many of these failures were caused by the risk attitude gaps among project stakeholder. This study aims to compare the risk attitude between the construction investor and loan investor. This study investigated how much differently 21 construction investors and 21 loan investor recognize the risk magnitude corresponding to the same three risk status of 27 risk factors. Construction investors show a more risk-seeking attitude than loan investor in 58 of 81 risk status. Loan investors show a more risk-averse attitude than construction investors in 9 risk factors. These results will contribute to developing the successful PPP project by reducing the risk perception gap between construction investors and loan investors.

Currently, as construction businesses develop and diversity, risk became one of the most crucial considerations. Risks are potential and difficult to predict by nature. Also, they are important as they influence delay in construction period and increase of project costs. In construction projects in South Korea and elsewhere, the importance of risk management widely recognized and relevant research is being conducted continuously. The companies use PRM checklist but apply different criteria and items. For efficient risk management in plants, plant PRM checklist is necessary. This study analyzed risk factors that are taken into account in construction projects and proposed a plant PRM checklist based on case analysis and opinions of experts. Also, it rated the frequency and importance of each risk.

With rapid industrialization since the 1960s, development projects have contributed to the development of the national economy. In addition to the development projects promoted by the government, private project operators are also promoting development projects for reasons such as increased public convenience, insufficient financing of SOC assets, and expansion of their own development projects other than public orders. However, as the economy has been stagnating due to several factors such as continued supply of facilities for decades and recent COVID-19, the success of the development projects are unsure these days. Therefore, this study attempted to analyze project costs through the case of such development projects, and to present a plan to judge and manage the risks of each project cost item in advance. The AHP technique, which is widely used as a risk factor selection method for existing development projects, was used, and items were determined through interviews with experts related to development projects in order to stratify the upper and lower subjects of the risk. We analyzed how the derived risk factors affect the business performance through sensitivity analysis, and finally substituted the risk factors management plan into the risk response strategy and suggested.
