Coupling Analysis of Risk Factors in Hydrogen Energy Storage-Transportation System Based on SNA and N-K Model
The fusion risk factor analysis system of complex social network(SNA)and N-K model was in-troduced into the safety risk assessment of hydrogen energy storage and transportation system.Through col-lecting hydrogen energy storage and transportation accidents in the past 20 years at home and abroad,mak-ing use of N-K model calculate risk coupling values and determine accident coupling forms,and employing the SNA to construct correlation network to calculate risk measurement,as well as combining SNA reacha-bility analysis with and N-K model,The closeness centrality was modified to determine key risk factors and relevant countermeasures were presented.The results show that,reducing probability of accidents can avoid multi-factor risk coupling form of operator-device-environment-management which cause accidents most likely.Talent team,management strength,rules and regulations,cultural level and professional skills become key risk factors that need to be focused on prevention.
