  • This study identifies various risk factors associated with activities of early 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 Common risks are identified and classified by considering various aspects of the early construction stage such as financial, political, constructional aspects, etc. The risks for Earth works and Foundation works are identified in detail by surveying technical specifications, relevant claim cases and interviewing with experts. These risks are classified based on the Wok Breakdown Structure(WBS) of the early construction stage. The WBS presented in this study classifies the works of early construction stage into four categories; excavation, sheeting works, foundation works, footing works. This study suggests a risk analysis method using fuzzy theory for construction projects. Construction risks are generally evaluated as vague linguistic value by subjective decision making. Fuzzy theory is a proper method to quantify vague conditions of construction activities. Therefore, this study utilizes fuzzy theory to analyse construction risks. The weight of risks is estimated by reflecting the interrelationship among risk factors from absolute weights obtained by fuzzy measure into the relative weights by Analytical Hierarchy Process(AHP). The interrelationship is estimated by Sugeno-fuzzy measure.

  • 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.

  • The building construction projects include a variety of risk factors due to uncertainties. To succeed in the projects, it is important how risks are managed. Risk management processes identification, analysis and response. Especially, the analysis process is important to objectively identify importance and priority among risk factors. The purpose of this study is to develop the effective analysis process by studying and supplement the problem of the AHP analysis method. The study provides a analysis process to use the PROMETHEE analysis method proposed.

  • 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.

  • The purpose of this paper is the provision of a decision-making tool for developers to identify the project risks for under-consideration overseas independent power projects (IPPs), and to analyze the priority and importance weights of the risks through the employment of a fuzzy multi-criteria decision-making (MCDM) approach. A fuzzy MCDM is the calculation method for which the imprecision of each respondent's unique opinion is considered. Through the extensive literature surveys that were conducted for this paper, eight major project finance (PF) risks have been derived credit risk, completion risk, market risk, fuel risk, operating risk, financial risk, environmental risk, and force majeure. The empirical results show that the market risk is the most important risk factor in terms of overseas IPPs, thereby confirming that the long-term power purchase agreement (PPA) guarantee of the host country is one of the most important corresponding factors for the PF.

  • Urban regeneration projects tingeing the shape of mixed-use development, due to the nature of the business, involve risk factors such as protracted business conflict among participations, subjects, complex approval and permission procedure, frequent policy changes, etc. Therefore, systematic risk management is needed to effectively manage the numerous risk factors that may occur during the process course of project. However, risk management of large and complex development projects such as urban regeneration projects is in the introduction stage yet and somewhat one time risk management plan has been established. Therefore, in this study, in order to systematic risk management of urban regeneration projects inhered numerous risk factors, risk factors for urban regeneration projects through preceding studies and case studies were presented. Also risk factors are classified in accordance with business propulsion phase, by estimating the importance for these, step by step emphasis on managed subjects of risk management was proposed.

  • The construction market is diversely changing because social environmental factors are rapidly transforming. Therefore, Construction projects are becoming complex and diverse. Furthermore, the risk being inherent in construction projects are increasing, and now people are considering about the risk management of construction projects in successfully handling the risk factor. The purpose of this study is first to comprehend the preparation of basic references for objective and systematic identification, categorization, and analysis of risk. Secondly it is to find the principle elements within the risk factors identified and categorized around planning process. Finally it is to manage objectively on the planning process, which forms a lot of uncertainty, in order to accentuate the importance about the risk of pre-planning process stage

  • 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.

  • In order to achieve the best performance of a project, uncertainties involved in the building construction process need to be identified in the planning phase of the project. Risk management plays a significant role in construction to minimize risk occurred due to uncertainties of a project. Although the importance of the risk management has been known to the construction industry, a more effective system should be developed to meet the demands of the industry. The purpose of this study is to develop the effective risk management system for scheduling the construction processes. The study provides a tool that can optimize the management system which would assist managers to identify schedule risks in the planning phase of the project.

  • Risks in construction projects are increasing remarkably due to recent changes in the construction environment. Active risk management is required to recognize risks as opportunities. The purpose of this study is to propose a risk management model of the importance determination method through comparative analysis using Kano model, Timko CSC (Customer Satisfaction Coefficient), and ASC (Average Satisfaction Coefficient). Based on previous studies, the validity of risk management factor determination is reviewed through a questionnaire modified Kano model through interviews with working-level workers using the Delphi technique. Through this, a suitable risk management model is presented by selecting key risk management factors recognized by domestic construction project practitioners. As a result of the study, the Kano model developed to verify risk management of construction projects was evaluated to be effective in verifying the risk management of practitioners. It is expected that the Kano model presented in this study will be actively used to verify the importance of risk management for construction projects.
