A Construction Safety Management System Based on the Complex Network Theory

摘要

Safety is one of the basic objectives of construction project management. Since a construction project involves different participants, processes, and influencing factors, safety management is a typically systematic and complex issue. Thus, this paper adopt the complex network (CN) method to illustrate construction safety management as a system. First, the mechanism of the CN theory and three kinds of network models were expatiated. Then, the topological structure of construction safety management was built. Construction safety management was decomposed to six groups, namely, organization, technical measures, resources, training, controlling, and contingency management about construction safety. Relations between the factors in different groups were described as a network diagram. Finally, according to the relation and probability of factors, reliability probability of subsystems and the whole system were calculated. The research provides a new idea and direction for the study on the reliability of construction safety management system.
