Risk Evaluation of Construction Project Based on Utility Function and Maximized Deviation

Risks of construction project are aroused by a series of factors with hierarchical structure, which includes main risk factors and sub-risk factors. Using the multidimensional features of risk factors to form utility function, and according to the evaluations of values of sub-risks given by experts to calculate the weights and then get the evaluations of main risks. Then we could use the results to assess the risk of whole construction project. The utility function and maximized deviation are employed during the whole process of calculation.
