Research On Game Analysis Of Third Party Safety Supervision And Determination Of Flight Inspection Object In Bridge Engineering

As an infrastructure,bridges have become an important part of the natural landscape while improving our traffic conditions.With the development of globalization,bridges as a transportation hub have a broad space for development.The state has paid more and more attention to the safety management of bridge construction,and the relevant legal system has become more and more perfect.However,there are still very few construction units seeking rent from the supervision unit,which leads to the supervision of the supervision unit.The safety management of the construction unit at the construction site is not standardized.In order to solve this problem,this paper discusses the introduction of third-party participation in bridge engineering construction safety management to improve the safety management level of bridge construction.This paper first reviews the status quo and research status of bridge engineering construction safety management,introduces system theory,principal-agent theory and safety management theory,understands the basic knowledge of relevant theories,and establishes a theoretical framework for the whole paper.Secondly,the third-party bridge engineering safety management research based on game theory is carried out.Firstly,the two-party game with the participation of third-party security management is established.Different optimal strategies can be obtained in different intervals.In this case,try to establish a three-party game model.Combining the dynamic equation with the linear programming method to find the equilibrium solution,combining the system dynamics with the evolutionary game to obtain two equilibrium solutions;since it is impossible to judge from the game model which equilibrium solution will be,with the help of simulation software The analysis of the strategic choices of each participating entity reveals that the third-party security management and construction unit will oscillate and amplify the center point around one of the equilibrium solutions,and the supervision unit will achieve strict supervision.By changing the size of the auxiliary variable to observe the changes in the choice of the participating entities,it is found that increasing the penalty for the construction unit and the supervision unit and increasing the number of third-party flight inspections is feasible for improving the violations of the construction unit and the supervision unit.Control strategy.Finally,27 out of 72 dangerous sources in the bridge engineering hazard source list were selected,and 27 hazard sources were sorted by AHP for reference by third-party flight inspection,so as to improve the safety management level of bridge construction.
