Using of fuzzy AHP for assessing risk of construction projects

Construction projects are affected by a variety of risk factors, and they often fail to achievetheir goals in terms of time, cost and quality. The frequency and impact of risks depend onproject-specific, contractor-specific and location-specific conditions. Identifying criticalsources of risk is crucial to minimize disturbance in project development and assure success,so risk should be analysed and assessed during all the stages of a construction project. Theauthors argue that applying fuzzy AHP – a technique invented to deal with imprecise anduncertain information obtained from a number of sources – facilitates aggregation of expertopinions on project risk and finding a compromise on weights and scores of risk sources. Thepaper presents risk analysis and assessment of a example construction projects to demonstratethe efficiency of the proposed method.
