Evaluation of Influencing Factors on the Supply Chain of Prefabricated Buildings under Engineering Procurement Construction Model: A Case Study in China

With strong support from national and local government policies for prefabricated buildings, China’s prefabricated buildings have entered a period of rapid development. This article analyses the literature from various countries and establishes a structural model of the prefabricated building supply chain under the Engineering Procurement Construction (EPC) mode. It analyzes the factors that affect the prefabricated building supply chain under the EPC model from eight aspects: design stage, prefabricated component production and manufacturing stage, procurement stage, and EPC general contracting stage, etc. Then, it establishes an AHP fuzzy comprehensive evaluation model that combines qualitative and quantitative methods to evaluate the entire lifecycle supply chain of prefabricated buildings, providing reference for the robustness and resilience evaluation of prefabricated building supply chains, and further achieving green management of cost reduction and efficiency improvement in prefabricated building supply chains.
