Complex network analysis on coupling evolution of accident scenarios in chemical industrial parks
To further study the issues of accident escalation caused by coupling effect in chemical industry parks,firstly,tak-ing the storage link of chemical industry parks as the research object,a typical accident scenario element framework system covering human factor layer,material layer,environment layer,management layer,combination layer and accident layer is con-structed from two perspectives of elements and relations.Then,based on topology theory and related methods,a complex net-work model of typical accident scenarios in chemical industry parks is constructed.The statistical characteristics of complex networks are analyzed to determine the network contribution of nodes and the vulnerability of connecting edges,and the most possible cause paths are explored.Combined with the evolution characteristics of accidents,emergency response countermeas-ures from the perspective of chain scission are proposed.Finally,the application case is used to analyze the most approximate cause path,and the preventive measures of related accidents are put forward.The research results show that in the case acci-dent,the initial stage is the key period of accident control in the chemical industry park.Strengthening employee training is one of the important means to strengthen the initial disposal,and the ignition source is one of the key factors for the accident coupling upgrade.The complex network model of accident scenario evolution in chemical industrial park constructed by has good practicability,and the most general reason is that the path is consistent with the actual situation.The research results can provide some references for accident prevention and evolution control in chemical industrial parks.
