Understanding Safety Performance of Prefabricated Construction Based on Complex Network Theory

With the rapid expansion of prefabricated construction in China, significant changes safety performance are still unapparent for numerous constructions, and accidents constantly exposed public. The ignorance interactions among risks impedes efficacious improvement, which instructs need a thorough analysis these based on complex network theory. This paper starts with identification 37 refined through literature review expert interviews, 90 interrelationships them verified by virtue questionnaire survey, laying foundation establishment risk (PCSRN). topological results prove that PCSRN is scale-free as well small-world network, indicates high-efficiency propagation diffusion constructions. Moreover, eight critical nodes identified four different ranking criteria, corresponding strategies proposed to address them. developed method not only provides novel insight interpret but also has potential advance this sector.
