Multidimensional and Interactive Assessment Model of Large-Scale Infrastructure Project and Its Demonstration Based on Double Utility

الملخص EN

This paper evaluates the project risks with a multidimensional and interactive model from multiagent and utility combination, which takes subjective psychological negative utility into account rather than only focusing on the thinking pattern of objective value loss.

Firstly, it analyzes the bodies’ heterogeneous preference and their game behavior using game theory application methods.

Secondly, it builds multidimensional and interactive evaluation model of large-scale infrastructure project from many dimensions, such as risk rate, objective utility, and subjective utility.

It reflects different values and behavior strategy interdynamic factor in the design of risk utility function.

Lastly, it deduces process and approaches of multidimensional and interactive evaluation by typical project.

In addition, it tests model parameter with regression analysis.

The research of this paper broadens the dimension of project risk evaluation and provides comprehensive and balanced reference for the measure of project risk utility and a better basis for project risk control.
