Research On The Stability Of J Company's Supply Chain Network

In recent years,the rapid development of digital technology has promoted the pace of enterprise transformation.As an important part of business operations,the digitization of the supply chain is also more urgent.In the traditional mode,the enterprise's supply chain operates in a step-by-step manner like a “chain”,but in the digital age,the “chained” operating mode has been subverted.Digital technologies such as cloud computing,Internet of Things,and big data transform the operation of enterprises from “chain” to “mesh”,which greatly enhances the interconnection between enterprises and externalities,and further enhances the connection between enterprises and suppliers and customers..At the same time of bringing this kind of convenience,the risks accompanying it are also coming.Due to the complexity of the supply chain network and the uncertainty of the external environment,various unstable factors make the supply chain vulnerable to various emergencies.The destruction makes the stability of the supply chain network very important.Research shows that the topology of the network largely determines the network characteristics.In view of this,this paper takes J company supply chain network as the research object,studies the relationship between supply chain network topology and supply chain network stability,and derives the topological nature of supply chain network structure that can effectively prevent risks.The supply chain network is a complex network with scale-free and small-world characteristics.Based on the perspective of complex networks,this paper focuses on the“topological structure of supply chain network”,“influencing factors of supply chain network stability” and “supply chain network stability measurement method”."The relationship between supply chain network topology and stability" systematically and deeply study the stability of supply chain network structure.Firstly,taking J company as the research object,based on the relevant data,the Matlab platform is used to simulate the dynamic evolution process of the company's supply chain network,and the empirical algorithm is used to solve the degree distribution,average path length and clustering coefficient of J company supply chain network.At the same time,it analyzes the topological properties of J company's supply chain network structure,determines the factors that affect the stability of the supply chain network,and uses the stability measureindex as the metric.Secondly,from the theoretical level,the "stereo-multi-core" nature and complexity of the supply chain network structure and the characteristics of its complex network are analyzed.Analyze the evolution process of supply chain network structure from the perspective of evolution mechanism,and then derive its evolution characteristics.Based on the evolution mechanism and characteristics of the supply chain network structure,the mathematical model and connection mechanism of the network structure are derived,and a complete supply chain network structure modeling system is formed.Furthermore,it lays the foundation for the simulation and verification of the dynamic and static attacks of J company's supply chain network structure.Finally,using Matlab as the development platform,the J company supply chain network attack algorithm was built.Through the setting and change of related parameters,random attacks and deliberate attacks were launched on the network.Finally,Matlab was used as the development platform to build the J company supply chain network.The attack algorithm initiates random attacks and deliberate attacks on the network through the setting and change of related parameters,exploring the number of attack nodes when the network fails,and then realizing the dynamic and static analysis of the stability of J company supply chain network.At the same time,it puts forward targeted risk prevention measures to enhance the stability of J company's supply chain network structure.
