Construction of multi-subject cooperative safety management evaluation system

With the rapid development of China's construction industry, the complexity of construction safety management and the need for multi-agent coordination are increasingly prominent. This paper takes multi-subject participation in construction safety management as the entry point, combines stakeholder theory, scientifically evaluates the safety production status of construction projects, and establishes the dynamic mechanism model of construction project safety management according to the logic of "elements → decision → behavior," and finds out the influencing factors of construction safety management. A set of scientific and dynamic safety management evaluation systems is constructed. First, through literature research and field investigation, the core subjects involved in construction safety management, such as construction units, supervision units, government departments and practitioners, are identified, and their responsibility boundaries and coordination mechanisms are analyzed. Second, the Delphi method and analytic hierarchy process (AHP) are used to establish a multilevel evaluation index system including five dimensions of "organization management, technical implementation, risk prevention and control, emergency response and collaborative effectiveness," and the entropy weight method is introduced to optimize weight distribution to ensure the objectivity of indicators and the correlation between subject and object. Through the empirical analysis of a large engineering project, the effectiveness of the system in improving the efficiency of safety management, reducing the incidence of accidents, and promoting the sharing of responsibilities among subjects is verified. The research shows that the evaluation system can quantify the collaborative efficiency of multi-agents and provide theoretical support and a practical path for the innovation of safety management modes in the construction industry.
