Evolutionary Game and Simulation of Subject Risk Management Behavior in Construction Stage of Engineering Project Based on Strong Reciprocity and Prospect Theory

In this study, to reduce the occurrence of risks and risk accidents in construction stages engineering projects strengthen management abilities subjects such projects, prospect theory is introduced into an evolutionary game construct a behavior model between owners contractors stage. addition, government penalty parameter based on strong reciprocity theory. The intrinsic laws optimal stability strategy evolution two parties are analyzed. influences different changes results simulated. study shows that has five local equilibrium points, positive for both stable strategy. factors influencing include cost management, perception loss its share ratio, discount coefficient, negative coefficient. differences perceptions effect hinder behaviors from evolving towards By means penalty, reciprocal can effectively coordinate strategies parties. Based analysis, suggestions proposed strengthening effective projects.
