Subjective Game analysis on the behavior of safety management in the high-risk-system based on Prospect Theory

The different strategies chosen by supervisors and workers will lead to different safety performance. The Prospect Theory was integrated into Subjective Game Theory and the Perceived Benefits Matrix, which was different from the payoff matrix, was constructed and used to study the behavior of safety management. The results had shown that eliminating the unsafe behavior must meet the four required conditions. But according to Prospect Theory and other theories of cognitive psychology, a conclusion was drawn that it was difficult to meet these four conditions in reality. This explained the paradox that unsafe behavior exists although it causes huge losses. Finally, the numerical simulation was performed to get the process in which the eight parameters, specially the psychological one, made the system achieve the desired state.
