基于弹性工程概念的作业人员安全绩效研究

Study on safety performance of first line operators in industrial enterprise based on resilience engineering concept

为提高企业作业人员安全绩效,引入弹性工程概念,总结提出基础弹性因子、行为弹性因子2个方面的7个弹性维度,并构建弹性工程概念对作业人员安全绩效的影响关系模型。根据一家国有化工企业的调研结果,利用多重中介的结构方程模型(SEM)与乘积分布算法进行量化分析,得到弹性概念维度对作业人员安全绩效的影响作用路径。结果表明,作业人员行为弹性因子直接影响安全绩效;4个基础弹性因子均可通过3个行为弹性因子不同的中介作用机制与作用效果,不同程度地正向影响员工的安全绩效;日常管理与事故预防行为分别为基础弹性因子与行为弹性因子中最具影响的弹性维度。

For improving the safety performance of the first line operators, 7 resilience dimensions related to work safety in enterprise, including basic resilience factors and behavioral resilience factors, were identified based on the resilience engineering concept, and a model was built for influences of the resilience dimensions on the performance. According to the investigation results from a state owned chemical industrial enterprise, a multiple mediation SEM based approach and a product distribution algorithm were applied to analyze the effective paths, along which the dimensions affect the performance. Study shows that the behavioral resilience factors of employee have a direct impact on safety performance, that the four basic resilience factors have different degrees of positive indirect influence on operators＇safety performance, mediated by diversities influence mechanisms of behavioral resilience factors of employee, and that monitoring and preparedness are the most influencial dimension in the basic resilience factors and the behavioral resilience factors respectively.
