正式网络中施工组织安全行为传播仿真分析

为了降低建筑施工安全事故发生率,借鉴社会网络理论与博弈论,使用多主体建模的方法模拟施工组织正式网络中组织安全行为传播的过程,通过Netlogo软件的行为空间工具收集不同情境下的仿真数据,使用回归分析方法分析网络结构特征和安全行为传播参数对组织安全行为的影响机制.结果表明:网络密度、出度中心势、聚类系数显著正向影响组织安全行为;中间中心势、平均路径长度显著负向影响组织安全行为;入度中心势对组织安全行为没有显著影响;组织自我学习安全行为的能力、传播安全行为的能力、吸收安全行为的能力、传播安全行为的概率、接受安全行为的概率显著正向影响组织安全行为.

Simulation Analysis on Safety Behavior Propagation of Construction Organization in Formal Network

In order to reduce the occurrence rate of building construction safety accidents, based on social network theory and game theory, the multi-agent modeling method was used to simulate the process of organizational safety behavior propagation in the formal network of construction organization. The simulation data in different situations were collected by the behavior space tool of Netlogo software, and the regression analysis method was used to analyze the impact mechanisms of network structure characteristics and safety behavior propagation parameters on organizational safety behavior. The results show that network density, outdegree centralization and cluster coefficient have significant positive effect on organizational safety behavior. Betweenness centralization and average path length have significant negative effect on organizational safety behavior. Indegree centralization has no significant effect on organizational safety behavior. The ability of organization self-learning safety behavior, the ability of propagating safety behavior, the ability of absorbing safety behavior, the probability of propagating safety behavior and the probability of accepting safety behavior have significant positive effect on organizational safety behavior.
