Fuzzy Probability Method-Based Risk Assessment of Engineering Project

From the angle of the project risk, the fuzzy probability theory is applied to appraise the risk. Firstly, the influential factors of the risk assessment for highway engineering project are analyzed according to the risk from the whole cycle of project. The risk of highway engineering project is divided into three parts, such as environmental risk, process risk and decision-target risk, and an assessment index system of highway project risk is constructed. Secondly, based on the fuzzy probability theory, a new model of risk assessment for highway engineering project is developed. In order to assess index weighted value scientifically, the analytic hierarchy process (AHP) is introduced into the fuzzy weighted values to avoid the uncertainties while determining the index weights. Finally, the validity and rationality of the risk evaluation for highway engineering project is verified through the risk instance of a project.
