Study On BIM Promotion Strategy Of Designer Base On Evolutionary Game Theory

BIM is widely used in the construction industry.It can be used in a specific part of the building,and can also be applied to the entire community or city.The main way using BIM is to use information technology to select the site for the project,parameterize the survey design,optimize the plan etc.The users of BIM involve multiple participants in the construction field.Currently,the main implementers of BIM are design companies.The design phase is also an important part of BIM application,which is critical to promote the application of BIM throughout the life cycle of projects.Due to various reasons such as the high incremental cost brought by the use of BIM and the slower benefits,the current designer's BIM application is not deep enough,and the result of promotion is not satisfactory.Therefore,it is necessary to study the influencing factors and behavior strategies that hinder the development of BIM from the perspective of the designer.From the perspective of the designer,this article focuses on the core issues of BIM promotion,summarizing the obstacles to the BIM promotion of the designer.And then the article refines the factors based on factor analysis.At the same time,combined with Stakeholder Theory,the influence subjects of the BIM promotion of the designer are further analyzed,and the main contradictions affecting the BIM promotion of the designer are highlighted.In order to find the key strategies to resolve the main contradictions,the evolutionary game model between the designer and the influential subjects were constructed based on the Evolutionary Game Theory.The evolutionary stability strategies of different games and the key factors affecting the stability strategies were analyzed.The game model was simulated by Python,which verified the analysis process and also provided a reference for finding out countermeasures and suggestions to promote the promotion of designer BIM.And the effect of parameter changes on the game results was studied.The study found that the designer's current application of BIM is relatively shallow,and the obstacle factors can be summarized into eight by factor analysis,such as incremental cost and management level etc.The main subjects that influences the designer's BIM application is the owner,similar design enterprises,and the government.From the evolutionary game between the designer and similar design enterprises,we can know that to promote the diffusion of BIM technology for the designer,the designer can improve the situation by improving the management level and strengthening cost control etc;From the evolutionary game between the designer and the owner,it can be seen that increasing the BIM budget of the owner to reward the designer cannot promote the diffusion of BIM technology for the designer,instead,the owner's income and subjective willingness to use BIM seem important;According to the evolutionary game between the designer and the government,the key countermeasure to promote the diffusion of BIM technology for the designer is to promote the incremental benefit of the designer over the incremental cost of the technology used,rather than the government's direct economic subsidy.Therefore,from the perspective of the two-party games,this paper proposes effective countermeasures to promote the diffusion of BIM for the designer based on the evolutionary game results,which has positive significance for promoting the application of BIM in construction industry.
