基于系统动力学的安全注意力专注与衰减研究

Research on safety attention concentration and attenuation based on system dynamics

为探索高危岗位员工安全事故发生概率与人机作业效率的平衡性机制,分析安全注意力与其影响因素间的因果关系,基于系统动力学(SD)原理,构建高危工作情境下安全注意力的影响因素系统模型。以煤矿矿工为研究对象,运用Vensim软件进行模拟仿真试验,探究矿工在特定系统变量条件下安全注意力专注、衰减及专注-衰减-专注过程的变化过程。结果表明,合理安排矿工的工作和休息时间能够保证安全事故发生概率与人机作业效率平衡性,并可降低矿工安全事故的发生概率。

To explore the mechanism of balance between high risk job employee safety accident probability and the man-machine work efficiency, the causal relationship between the factors influencing and the safety attention was analyzed. Based on SD principle, an influencing factors system model was built for safety attention employees in a high-risk work scenario. Coal miners were taken as the research object. A simulation was made by using ~ensim software for exploring the changing process of safety attention concentration and that of safety attention attenuation and that of safety attention concentration-attenuation-con- centration. The results show that the reasonable arrangement of employee＇s work and rest time is helpful in insuring the balance between employees safety accident probability and man-machine work efficiency and reducing the probability of safety accidents.
