Research on safety management of construction projects based on game theory

摘要

Shortage of construction project safety management has been one of the problems that hinder the development of construction industry. Strengthening the construction safety management can not only promote the development of the construction industry, but also promote the social stability. This paper uses game theory to study the relationship between the main parties of construction project from the macro perspective. In this paper, we first use the static game theory of mixed strategy to establish the game model between supervision units and contractors, then use principal-agent system to establish the game model between owners and supervision units, and finally use the first model into the second model to construct an extensive form between owners and supervision units and contractors. Furthermore, in this paper, we obtain the construction project safety equilibrium point and put forward the safety management strategy for the supervision unit and contractor. Finally, the application of the model is introduced by a case study.
