Fuzzy Analytical Hierarchy Process(FAHP) Approach to Risk Assessment in Ethiopian Building Construction Projects.pdf

1、The major objectives of construction projects have high exposure to be affected byvarious risks throughout the project life cycle.Thus, applying effective riskmanagement enables the managers to meet project objectives in

2、 terms of schedule, cost,quality and scope.In this research work, fuzzy analytic hierarchy process (FAHP) riskassessment approach is presented in order to prioritize project risk factors systematically.Risk assessment is

3、 the core process of risk management which includes riskidentification, analysis and prioritizing project risks.The proposed risk assessmentmethod is applied in Ethiopian building construction projects.Thirty project ris
