Analysis of influencing factors of construction safety of prefabricated buildings based on Fuzzy-ISM and MICMAC

As a new building production mode, the construction method of prefabricated buildings is quite different from that of traditional buildings, and the construction safety management at each stage is more difficult. In order to reasonably analyze the relationship between the construction safety risks of prefabricated buildings, this paper identifies 5 types of 26 risk factors, and builds a multi-level hierarchical structure model of construction safety risks of prefabricated buildings based on Fuzzy-ISM. And MICMAC is used to calculate the driving force and dependence of each risk to classify the risk. It provides some reference for the identification, analysis, evaluation and early warning of the key risks in the construction management of prefabricated buildings.
