최근 기술의 급격한 발달과 기업환경의 변화 및 자연환경의 변화로 인해 다양한 리스크 문제들이 대두되고 있고 리스크의 범주도 확대되고 있다. 리스크 관리 실패는 기업 및 국가경쟁력에 상당히 많은 영향을 미친다. 기업 및 국가에서는 리스크를 관리하기 위해 리스크경영시스템을 구축하고, 리스크를 최소화하여 리스크로 인한 손실비용을 줄이기 위해 노력하고 있다. 이에 본 논문에서는 국내외 리스크경영시스템 및 리스크 관리, 리스크 분석기법들을 조사 연구하여 리스크경영시스템 구축에 있어 필요한 기초자료들을 제시하고자 한다.

Due to the significant size of overseas construction projects, the cost overrun has enormous impacts on the financial status of construction companies. The managers' appropriate perception and identification of key risk factors in the construction phase notably affect the performance of projects. However, the actual impacts of risk factors and local manager' s perception of them could be deviated. For this reason, we aim to compare the performance of actual cases and general opinions of responsible practitioners in terms of risk factors relevant to cost overruns in order to present a practical strategy for risk management. Firstly, factors classified from literature review were used to simulate 290 cost overruns data sets from 20 cases by introducing Monte-Carlo Simulation and were ranked by standardized coefficients through multiple regression analysis. Secondly, a survey was conducted against 42 local managers to rank their perception of impact on cost overrun with identical factors by using Stepwise Weight Assessment Ratio Analysis (SWARA). Comparison results show that conflicts such as 'conflict with subcontractors' and 'conflict with the local community' have caused excessive cost overrun. However, managers' perception of these as less significant than the actual influences and consider other risks such as 'material price fluctuation' and 'construction quality errors', as relatively serious. Therefore, education for local managers on conflict risks needs to be presented.

Construction projects are exposed to various types of risks, which tend to increase. The increasing risks call for contractors' more attentions to forecasting and dealing with these risks. One of the measures to deal with contractors' risks is to forecast or estimate risk cost and include it in the construction budget. Although various researches in relation to risk cost have been observed, little attention has been paid to general contractors' perceptions and current practices in estimating risk cost of construction budget. The objective of the study is to identify and discuss key characteristics and implications based on the survey and analysis of general contractors' perceptions and current practices in estimating risk cost of construction budget. The study shows that there is a gap between the perception and the practice of estimating risk cost, that is, high perception of the importance of risk cost and a relatively low level of practice. It suggests that historical cost data, guidelines and corporate-level standard procedures are required to improve the current practice in addition to sufficient time allocations for risk cost estimating. It discusses that there is a need for using sophisticated estimating techniques including bid data analytics despite a low level of the current adoption, and also proposes that research and development in the field of the sophisticated estimating techniques should be further implemented in order to increase their practicality.

프로젝트에서 리스크 관리란 프로젝트 진행 시 발생가능성이 있고, 프로젝트에 긍정적 또는 부정적 영향력을 가진 이슈를 미리 발굴하여, 효과적으로 관리하기 위한 기법이다. 이런 점에서 리스크 관리는 프로젝트 목적 달성 즉 성공을 위한 수단이며, 예기치 못한 사건에 대한 사후대책 보다는 사전대책의 특성을 가지고 있다. 이러한 리스크 관리에 대하여 건설, 금융, 국방, 공공 분야의 프로젝트에서는 그 중요성을 인식하여 다양한 분야의 연구가 활발히 진행 중이고 현장에서도 활용하고 있으나, 소프트웨어 개발 프로젝트에서는 아직 그 중요성에 대한 인식이 부족하고, 현장에서의 활용도 저조하다. 반면 소프트웨어 개발 프로젝트에 대한 고객의 요구사항(비용절감, 일정 단축, 품질 향상, 신기술 적용등)은 점점 복잡해지고, 정교해지고 있어 제한된 리소스로 개발을 진행해야 하는 프로젝트 팀 입장에서는 프로젝트 성공에 대한 부담감이 점점 증가하고 있다. 본 연구에서는 리스크 관리를 수행한 프로젝트와 그렇지 않은 프로젝트의 사례를 비교하여 리스크 관리가 프로젝트 성공에 미치는 영향에 대해 연구하였다.

The Project Risk Management is intended to result in the effective management by identifying in advance and mitigating all significant risks including project risks and opportunities during the entire project life cycle - from project inception to completion of construction. It is impossible to predict an exact budget and construction duration before finishing a project. So, Washington Department of Transportation mandates that workshop-based risk management is conducted for projects over specific cost. However, the domestic construction sites have depended on numerical risk analysis without any workshop and efficient risk management have not made. Therefore, in this study, we propose the effective risk management using the RBES program which is very useful for workshop-based risk management and pre & post mitigation, by workshop-based risk management techniques. This proposed risk management approach is applied to a domestic 'A' river recovery project. It is concluded that we may expect the effect to mitigate the total cost overrun problem and the construction duration delay effect in the project by identifying significant risks and by preparing effective risk mitigation strategies.

소프트웨어의 사용영역이 확대되고 개발 규모가 거대화되고 복잡해 짐에 따라 소프트웨어의 품질과 생산성이 중요해지고 있다. 이러한 상황에서 프로젝트의 리스크를 식별하고 그에 따른 파장을 최소화하는 리스크 관리는 소프트웨어 개발 프로세스의 핵심 관리 기술로 부상하고 있다. 본 논문에서는 기존의 소프트웨어 개발 관리 프레임 워크 상의 리스크 관리를 연구하여 보다 정형화된 리스크 관리 프로세스를 제안하고, 그에 따른 비즈니스상의 효과를 보여준다. 또한 리스크 요인과 프로젝트 혼란 사이의 통계적 예측 식을 제시한다.

Recent public information project, which has been organized mainly to large companies is a situation that is being reorganized to small and medium-sized systems integration company. However, many of the small and medium-sized companies lack knowledge of the systematic risk management. Thus, in connection with the revenue, it involves a number of problems. Therefore, in this paper, we present a risk element that occurs mainly in the field of the project, providing a model for measuring the risk element by risk level costs associated with this. Through the convergence, we aim at providing a management system that is able to make the project successfully accomplished, predicting the risk that occurs in advance to pursue the project; Based on the proposed model, it is possible to secure a proper size of reserve fund so it is expected to enable companies to ensure the cost of risk analysis.

Project risk factors are major triggers in cost performance in construction projects. Both owners and contractors are highly concerned in managing their risks in earlier times. As such, it is needed to provide a robust risk evaluation methodology in identifying and assessing the potential risks before project execution. In previous research, risk identification was conducted only in specific phases, i. e., design, procurement, construction. Therefore, the comprehensive approach in risk management was limited and their quantifying method was not well-defined. Since the benefit of planning in earlier times are maximized compared to later times, the risk management should be implemented in earlier planning stage. This study provide a new risk evaluation method by incorporating previous research and extensive literature review. By quantifying each risk factor from an extensive industry survey, the proposed tool can enhance the reliability of each factor weight and also the weights are categorized from a various perspectives, i.e., owners, contractors, lager-scale company, smaller-scale company, building projects. The proposed tool can be also useful in deciding on whether to proceed a particular project and How much the project contingency would be set aside in project execution. The study findings can also expedite the risk management procedure in a more systematic approach.

The apartment reconstruction project is making some problems, such as delay of lack specialty, conflict between project owners and cost increasing etc. The enforcement process of project are very complicated, the term of project is long and too many project owners are participating. For this reasons. it is always in the face of uncertainty. To promote the reconstructing project successfully. we need to make risk management process to get rid of uncertain factors which occur in forwarding the reconstructing project This study has for its objects. First, suggest the best way of risk analysis to manage risk factors systematically and efficiently recognized in The Apartment reconstruction protect. Second, furnish basic data to build the risk managing system of The apartment reconstructing project.
