Collaborative Network Analysis Of Petrochemical Fire Emergency Response

Once a fire accident occurs in a petrochemical enterprise,it is very likely to cause multiple impacts,endangering people’s lives and social security.Therefore,an effective emergency response system is needed to deal with it,and carry out real-time information sharing,emergency coordination,resource allocation,etc.,and cooperate to complete emergency response.However,due to the tight time for emergency response to fire accidents and the large number of task-heavy response organizations,it is easy to cause problems such as poor information communication between emergency organizations,improper command and command,and uneven resource allocation,which reduces the efficiency of collaborative emergency response.Therefore,this thesis focuses on the collaborative network among organizational members formed in the petrochemical fire emergency response,and explores how the relationship between different emergency response organizations affects the overall emergency rescue network in emergency situations.The thesis takes the fire in the storage tank area of petrochemical enterprise as the background,on the basis of summarized and analyzed the research status and development of emergency response collaborative network at home and abroad,based on the social network theory and collaborative theory,this thesis mainly completes the following work:（1）Completed the actual emergency action based on a petrochemical storage tank fire and combined with the response plan to analyze the petrochemical fire emergency response process.（2）The emergency response collaborative network model was constructed,including 2-model and 1-model network models,which included node identification,identified relationships between actors,association matrix establishment,and finally visualization of network topology through UCINET and NETDRAW.（3）The basic characteristics,network structure and network performance of the emergency response collaborative network were explored from the macro and micro perspectives,and the results showed that: Both 2-model and 1-model networks show a certain degree of clustering.The overall density of 1-mode network is relatively low,and the degree of cooperation and interaction between most actors is not enough,but the response efficiency is relatively fast,and the supply of resources and other aspects may not be able to meet the demand quickly.The headquarters,the director of company management,control room,the vice-general manager of the company and the fire brigade 119 all have high degree of dispatch centrality.They can output more information,resources or on-site instructions and have certain influence.This part also conducts a comparative analysis of empowered networks,and mines the hidden key actors and relationships in emergency response actions through core-edge algorithms.（4）The dynamic changes of the emergency coordination network were excavated from the perspective of time,and the synergistic relationship,network evolution and network performance among emergency response actors under different time states are analyzed.it is found that the number of response actors joining the collaborative network gradually increases,and the collaborative interaction relationship also increases,but the increase is small.The density of the dynamic collaborative network increases from dense to sparse,the average distance between network members is also increasing,and the network structure becomes more and more dispersed.The status and roles of different actors also change dynamically over time,and the core actors are also different in each stage.（5）Finally,according to the above analysis results and the specific conditions of petrochemical enterprises,measures to optimize network organization relationships and nodes were proposed.And at the same time,it also provides a certain reference for the formulation of petrochemical fire emergency plans and collaborative response.
