摘要:

为解决作业相关人员安全职责边界模糊以及履责过程中多岗位、多环节安全职责交互关系不清晰的问题,引入功能共振分析方法(FRAM),构建有限空间作业安全职责系统半定量分析模型,展现多岗位间安全职责交互和协同配合关系,通过定量化系统功能单元的上下游耦合变异性,理清系统各功能要素间耦合作用影响机制。结果表明:基于FRAM的有限空间作业6方人员安全职责全局系统变异性数值为1.99×1010,下游功能单元F5(作业人员)和F6(应急救援人员)的输入可变性影响数值分别为171.5和250,受上游功能单元的耦合变异影响较大,易产生不良事故后果,结合有限空间作业8类关键影响因素分析功能共振结果,针对2个上游功能单元和6条失效链路提出加强作业安全投入等有效屏障措施。

Abstract:

FRAM was introduced to build a semi-quantitative analysis model of operation security duty relation in order to solve problems such as the fuzzy boundary of security duty of operation-related personnel and the unclear interaction of multi-post and multi-link security duty in the process of performing duties. Quantifying the upstream and downstream coupling variability of the functional units clarified the influence mechanism of coupling among the functional parts of the system. The findings demonstrate that the global system variability value of safety responsibilities for 6 parties involved in confined space operations based on FRAM is 1.99×1010, and the input variability impact values for downstream functional units F5(Operators)and F6(Emergency responders)are 171.5 and 250, respectively. The coupling variation of upstream functional units has a significant impact on the system and is prone to adverse accident consequences. Combined with the functional resonance results of the analysis of 8 types of critical impact factors for confined space operations, effective barrier measures such as strengthening operational safety inputs are proposed for 2 upstream functional units and 6 failure chains.
