近年来，研究者们越来越多地关注工人安全行为的社会和认知方面。同样，研究人员已经开始对工人安全行为的社会认知过程进行建模。然而，对工作组变动对社会影响力的影响的调查仍然有限。施工项目中的工作组会动态变化，因为工人会根据项目进度进进出出。考虑到工作组的变化会影响项目的社会网络，而社会规范的传递是通过社会网络发生的，因此应该考虑工作组的变化。本文建立了一个基于智能体的模型来研究工作群体变化的动态性如何影响工人安全行为的社会认知过程。在三种现场风险条件下(即低、中和高现场风险条件)，进行了三个实验，考察了工作组变化的动态性[即静态(不周转)、适度动态(适度周转)和高度动态(高周转)]的影响。结果表明，在中等风险和高风险条件下，静态和轻度动态变化的发生率显著高于高动态变化，而在低风险条件下，三种动态变化的发生率差异不显著。这些发现通过探索工作组变化和工地风险条件之间的相互作用，为建筑从业者提供了对安全管理干预措施发展的洞察。此外，本研究还通过检验工作组变化在工人安全行为的社会认知过程中的重要性，为建筑安全知识体系做出贡献。
Recently, researchers have paid increased attention to the social and cognitive aspects of workers’ safety behaviors. In the same vein, researchers have begun modeling the socio-cognitive process of workers’ safety behaviors. However, an inquiry into the impact of workgroup changes on social influence remains limited. Workgroups in a construction project dynamically change because workers enter and leave according to the project schedule. Considering that changes in workgroups affect the social network of the project, and the transmission of the social norms occurs through the social network, workgroup changes should be considered. In this paper, an agent-based model is developed to investigate how the dynamicity of workgroup changes affects the socio-cognitive process of workers’ safety behavior. Three experiments examining the effect of the dynamicity of workgroup changes [i.e., static (no turnover), mildly dynamic (modest turnover), and highly dynamic (high turnover) change] in three site risk conditions (i.e., low, modest, and high site risk conditions) were conducted. The results indicate that while the incident rates for the static and mildly dynamic changes are significantly higher than the highly dynamic changes in the modest and high-risk condition, the differences in the incident rates for the three dynamicity changes are not significant in the low-risk condition. The findings provide construction practitioners with insight into the development of safety management interventions by exploring the interaction between the workgroup changes and site risk conditions. Also, this study contributes to the body of knowledge of construction safety by testing the importance of the workgroup changes in the socio-cognitive process of workers’ safety behaviors.
