Abstract

Abstract:

Design changes represent one of the main risk factors that affects the performance and safety of prefabricated building projects. Multi-stakeholder participation in prefabricated component supply chains involves a complex and changeable system, and information integration of each participant is difficult. This in turn makes it difficult for the project to achieve systematic and effective design change risk management and control. Based on the induction of design change risks and risk-causing factors, a method that combines a structural equation and multi-agent simulation model is proposed in this study. Management strategies are first proposed based on the identification of risk-inducing factors. The actual operational effects of these management strategies are then simulated to achieve an optimal allocation of resources. Based on a prefabricated construction project in Nanxiang Town, Shanghai, an ontology instance library is established, and the proposed management strategies by empirical analysis of the structural equation model are simulated through the multi-agent simulation model. The effects of the strategies on project cost and time performance are evaluated, and the feasibility and effectiveness of the model are verified.
