| Abstract: | In order to study the dependency of physical devices,information network and human operation of land-based LNG unloading system and the influence of information layer and human layer on the fault propagation of device layer,a fault propagation analysis method of LNG unloading system was proposed from two aspects of static risk analysis of single-layer network and dynamic propagation of multi-layer dependency network based on the infrastructure resilience-oriented modeling language (IRML).The results showed that the fault propagation model of dependency network could obtain the dynamic characteristics affecting the fault mode and fault propagation state of the system as a function of time.It can further provide the basis for the coupling fault tracing and system recovery prediction. |

| Keywords: | LNG unloading system dependency network fault propagation infrastructure resilience-oriented modeling language (IRML) |
