An Analysis on the Key Influence Factors for Intelligent Construction of Prefabricated Buildings Using DEMATEL-ISM

Intelligent construction refers to a new generation of artificial intelligence and engineering construction that has been naturally integrated into a new construction process. It can be effectively incorporated with prefabricated structures. To scientifically improve the application possibilities of intelligent construction, it is necessary to identify and analyze the key factors influencing its application to prefabricated buildings. This study presents the overall functional architecture of an intelligent construction system for prefabricated buildings and identifies 19 parameters of four aspects from the prefabricated buildings life cycle. To identify the key factors and causal relationships, Decision-Making trial and Evaluation Laboratory (DEMATEL) is employed, in conjunction with Interpretive Structure Modeling (ISM), to construct a multilevel progressive structure model that also clarifies the action pathways of these factors. The feasibility of the proposed methodology has been demonstrated through case analysis. The results show that policies and regulations, technical standard systems, talent quality, and technology and innovation investment are the deep-seated influencing factors in the application of intelligent construction of prefabricated buildings, and the development suggestions are proposed accordingly.
