Abstract
In order to solve the problems of prefabricated residential building supply chain, such as more risk factors, high uncertainty and the influence of risk source factors, DEMATEL-ISM method is proposed to analyze the relationship between risk factors. From the outside, management. Manufacturing and transportation, construction and assembly, delivery six aspects of the establishment of risk index system. Combined with the analysis of examples, it is concluded that the total contract management ability and subcontract management ability are the most fundamental influencing factors of the prefabricated residential building supply chain risk, and have a great impact on other factors. Prefabricated installation precision, transfer layer steel bar positioning, delivery timeliness, quality acceptance are the surface factors of prefabricated residential building supply chain risk, and the impact is small. The research results can provide ideas for the correlation of supply chain risk in related projects.
