Project Risk Assessment Model Based on Entropy Theory

In the past, the risk assessment of construction projects focused on the static qualitative research, and the weight selection was subjective. To make up for the influence of such aspect on the effect of project risk assessment, this paper adopts the systematic and dynamic risk assessment and analysis method based on the theory of information entropy weight. It combines the quantification of information with probability analysis, and determines the weight of each index of the risk matrix, to make risk decision for the engineering project. Finally, through the example analysis, the information entropy is implemented on the analysis and evaluation of the actual project risk factors, which proves that the scheme can reduce the risk cost and maximize the enterprise benefit.
