【摘要】：供应链环境下企业组成的网络在运作过程中，个别节点企业由于自身管理不善或是外部环境恶化等原因出现风险后不仅会对其自身正常运营造成影响，还可能借助企业间的关系网将风险传播至其他企业，甚至导致整个网络崩溃，，进而在一定程度上影响经济、社会的和谐发展。因此，对供应链环境下企业风险传播的研究成为了一个亟待解决的问题。本文以复杂网络理论为基础，将供应链环境下企业组成的网络及其主体行为结合起来，仿真企业风险传播过程。通过查阅文献，归纳出供应链环境下企业风险传播的研究现状；分析企业风险基本构成要素和传播模式，研究它的传播过程；构建了基于风险的供应链复杂网络模型，并提出相应的网络统计特性；在模型的基础上运用Matlab软件编程实现仿真网络中单个企业突发风险、多个企业同时发生风险和预警机制下单个企业突发风险三种情况下企业风险的传播过程及其统计特性变化，分析供应链中的企业风险传播的宏观演化规律；结合仿真结果提出防范与控制措施；最后，对本文研究内容及未来发展趋势进行总结与展望。本文基于复杂网络模型探讨供应链环境下企业风险传播的宏观演化规律，对人们掌握供应链环境下企业组成的网络功能特点及其风险传播动力学机制有着极其重要的作用。该文不仅具有重要的理论意义，而且具有潜在的应用价值。
[Abstract]:Supply chain enterprise under the environment of network in the process of operation, the individual node enterprises because of its own mismanagement or deterioration of the external environment and other reasons the risk will not only affect the normal operation of its own, possibly by means of net relationship among enterprises will risk spread to other enterprises, and even lead to the breakdown of the network, thereby affecting the the economy in a certain extent, the development of a harmonious society. Therefore, the research on risk communication enterprise under supply chain environment has become an urgent problem.
This paper is based on the theory of complex network, the supply network and its main component of enterprise behavior chain under the combined simulation of enterprise risk propagation process. Through the literature, summarized the current research status of enterprise under the environment of supply chain risk communication; analysis of basic elements and the mode of communication of enterprise risk, it constructs a communication process; the risk of complex supply chain network model based on network, and put forward the corresponding statistical properties; simulation for single enterprise network burst risk using Matlab software programming on the basis of the model, the change propagation process and the statistical characteristics of enterprise risk and early warning mechanism of single enterprise risk of sudden three case risk occurred at the same time many enterprises, analysis the macro evolution of enterprises in the supply chain risk transmission; with the simulation result, the prevention and control measures; finally, the The research content and future development trend are summarized and prospected.
This paper discusses macro evolution laws of complex network model of enterprises under the environment of Supply Chain Based on risk communication, plays a very important role in people grasp the network features and dynamic mechanism of risk communication enterprise under the environment of supply chain. This paper not only has important theoretic significance, but also has potential application value.
