Study On Resilience Evaluation And Subsystem Coupling Coordination Degree Analysis Of Emergency Logistics System In Shanxi Province

At the time of the new coronavirus outbreak,the logistics industry is facing a severe test.Because of major health emergencies,a large number of logistics activities are often carried out.As the backbone of the fight against the epidemic,the construction of emergency logistics is a key factor in the success or failure of the prevention and control of public health emergencies.Emergency logistics is an important link in the emergency management system.How to respond to the occurrence of public health emergencies quickly and effectively,improve the capacity of emergency logistics and reduce losses has become a hot topic of research.Aiming at this problem,this paper makes a comprehensive evaluation and analysis of Shanxi emergency logistics system using comprehensive literature research,comprehensive index method and entropy weight method,and puts forward some suggestions for improving Shanxi Shanxi emergency logistics capability.Firstly,this paper introduces the concepts of emergency logistics and system toughness,as well as the theory of complex systems and coordination theory as the theoretical basis for further research.Then,based on the existing study on the evaluation of the resilience of the emergency logistics system in Shanxi province,19 indicators were selected from the three parts of basic security,logistics transportation and information processing to construct the resilience evaluation system of the emergency logistics system scientifically.In time,this paper takes the resilience index of the emergency logistics system in Shanxi Province from 2016 to 2020 as the research object,obtains the resilience index of the system in each area during this period and analyzes it through the evaluation model.The spatial aspect is to compare the trend of the resilience of the emergency logistics system in Shanxi Province in 2016-2020.;Coupling coordination measurement model of interaction of several systems is extended to each subsystem in an emergency logistics system by reference to the concept of volume coupling and its coefficient model in physics.The evaluation results show that the overall toughness of Shanxi Province evolves from a low-level toughness state to a high-level toughness state.In the time series,the toughness index of the emergency logistics system in Shanxi Province from 2016 to 2020 went through three stages,namely,"rapid uplift-slight rebound-slow and steady uplift." In the regional distribution,the toughness index has gradually changed from the north-south lead to the central prominence,which leads to the improvement of the toughness index in the surrounding areas.The index of subsystem coordination evolves from a serious imbalance to a barely coordinated direction,and although the overall coordination has been steadily increasing,the problem of barely coordinated still exists.Finally,the diagnosis results are classified by "precision management",and the key factors affecting the toughness of local emergency logistics systems are excavated by the contribution analysis method in areas with low toughness.In the area with a low coupling degree,the reasons for subsystem lag are analyzed and the corresponding solutions are put forward.
