Analysis on Safety-Affecting Factors of Prefabricated Construction Projects with Dematel-ISM

In order to improve the safety management level of prefabricated construction projects, the safety influencing factors are extracted from the characteristics of the construction site and the safety incidents. Decision making trial and evaluation laboratory (DEMATEL) and interpretive structural modeling (ISM) are used to analyze the relevance of the safety-affecting factors and their location in the safety architecture of the prefabricated construction site. The result shows that the safety of prefabricated construction projects is affected by root factors, transmission factors, and direct factors. Controlling the root factors and key transmission factors can improve the direct factors, which are conducive to improving the stability of the safety system on the construction site of the prefabricated construction projects.
