Risk factor identification method of ship refueling system based on IRML-STAMP
In order to study the changes in the functional state of the ship refueling system after external in-terference and its own recovery ability,the IRML-STAMP method was used to identify the risk factors of the ship refueling system,quantitatively evaluate the dynamic resilience of the ship refueling system,and compare the results with those based on traditional STAMP methods.The results show that the IRML-STAMP method can accurately identify the key nodes of the STAMP model that cause the maximum dy-namic resilience loss of the ship refueling system after failure.Taking the fault scenario of the refueling op-eration setting in the ship refueling system as an example,the pressure gauge and other instruments are the key nodes of the system.After the interruption of the pressure gauge and other instruments,the dynamic resilience of the system significantly decreases by 0.161.When the fault propagation path does not include critical nodes,the system has the maximum dynamic resilience.When interference occurs at critical nodes,the system has the minimum dynamic resilience,with a difference of 0.101.Compared with traditional methods,this result can accurately locate system risks and improve system dynamic resilience.The result can help improve the anti-interference ability of ship refueling systems and has guiding significance for i-dentifying risk factors in on-site ship refueling systems.
