Hierarchical Fault Propagation and Control Strategy from the Resilience Engineering Perspective: A Case Study with Petroleum Refining System

摘要

Although fault propagation scenario-based accident analysis can be an effective means to help operators to find the root causes of the current abnormal event, it has not yet been analyzed from the resilience engineering (RE) perspective. Resilience engineering is a new method that can control incidents and limit their consequences. This study introduces a hierarchical fault propagation model (HFPM) as an extension of the Infrastructure Resilience-Oriented Modelling Language (IRML), considering the dynamic behaviour of fault propagation. The method involves two parts: the first part is static analysis for system structure feature and the second part is dynamic analysis for fault evolution mechanism. The performance of the proposed model has been tested on a petroleum refining system with the characteristics of complex, non-linear and multivariate.
