Good cooperation mechanism is an important guarantee for the advancement of industrialization construction. To strengthen the partnership between producers, we analyze the behavior evolution trend of both parties using an evolutionary game theory. Based on the original model, the mechanism of coordination and cooperation between prefabricated producers is explained under the condition of punishment and incentive. The results indicate that stable evolutionary strategies exist under both cooperation and noncooperation, and the evolutionary results are influenced by the initial proportion of both decision‐making processes. The government can support the production enterprises to establish a solid partnership through effective punishment and incentive mechanisms to reduce the initial cost in the supply chain of prefabricated construction, resulting in a win‐win situation.

This study establishes a tripartite evolutionary game model based on the assumptions of bounded rationality and the interaction behavior of governments, owners, and general contractors to examine how strategies are changing for three stakeholders regarding the building information modeling (BIM) application in engineering-procurement-construction (EPC) projects. The theoretical model was validated and the effects of critical factors on stakeholder decision making were discussed using case study and numerical simulation analysis. The results show that (1) the choice of the BIM application strategy in EPC projects is affected by the interactive behavior of participants in the game, (2) the reasonable subsidies contribute to the evolution of the ideal stable strategy, (3) the owners’ high standard of incentives for general contractors can accelerate BIM promotion, (4) the general contractors are more sensitive to the loss that may be caused by problems with the BIM application, and (5) the positive externalities generated by the application of BIM have a great impact on the wide application of BIM. And some suggestions are put forward toward improving the development of BIM in EPC projects on the basis of findings. This study may contribute to our current understanding of the interactions of stakeholders in EPC projects, as well as provide valuable management implications for the governments in order to promote the development of BIM.
As a sustainable and cleaner type of facility, prefabricated buildings face more design barriers than traditional non-prefabricated buildings. Identifying and managing these barriers is key to improving the success rate of prefabricated building design. However, direct studies on these design barriers are extremely rare. The present study solved this problem by combining multiple methods, including grounded theory (GT), structured self-intersection matrix (SSIM), analytic network process (ANP), and the linear weighted sum method (LWSM). GT was adopted to identify the barriers to prefabricated building design and then SSIM was used to analyze the interactions among them. The eight design barriers were finally identified and classified into three clusters: technical barriers, economic barriers, and management barriers. A further analysis found that there is dependence and feedback among these clusters. The technical barrier cluster and management barrier cluster experience self-feedback. A network model based on ANP was next established to calculate the weights of the barrier elements and then this model was combined with LWSM to evaluate the overall design barrier strength of a project case. The results showed that architectural individualization has the greatest impact on prefabricated building design, followed by the collaborative issues among multiple units and professional designer issues. The overall design barrier strength of the project case was larger. Therefore, the first suggestion provided to the facility management sector is to establish a library for standard house types to achieve architectural design through multihouse combinations.
