为解决复杂过程中的人-机-环耦合危险识别及其传递性分析问题,将过程故障模式与影响分析(PFMEA)和层次分析法(AHP)相结合,并加以改进,建立用于分析过程耦合的新方法。首先分解、描述过程,确定其中的人-机-环边界条件,据此分析过程中的耦合危险模式及其引发的安全后果;然后通过AHP法识别复杂过程中的事件关系,分析耦合危险对后续过程的影响;最后,以美军某舰载机着舰过程为例,进行耦合危险分析。结果表明,用该方法能有效识别过程中的耦合危险,并评估耦合危险对后续过程的影响。
In order to solve the problem of man-machine-ring coupling hazard identification and its transitivity analysis in complex process, PFMEA and AHP are combined and improved to establish a method for analysis process New method of coupling. First of all, the process of decomposition is described and the boundary conditions of human-machine-ring are determined. Based on this, the coupling hazard model and the security consequences are analyzed. Then, the relationship between events in complex processes is identified by AHP, The impact of the process; Finally, take a US aircraft carrier aircraft landing process as an example, the coupling hazard analysis. The results show that this method can effectively identify the coupling hazards in the process and evaluate the influence of the coupling hazards on the subsequent processes.
