突发公共事件下复杂供应链网络风险传播与干预
Risk Propagation and Intervention in Complex Supply Chain Networks During Unforeseen Public Events
摘要
Abstract
Unforeseen public events present substantial challenges to the stable operation of supply chain networks.It is of paramount importance to enhance the capacity of these networks to respond to unforeseen public events while preserving their resilience and stability.In consideration of the unique characteristics of such events,this paper formulates a risk prop-agation model for intricate supply chain networks under the influence of government intervention,utilizing an enhanced SEIR system dynamics transmission model.It employs the basic reproduction number theory to scrutinize the thresholds and equilibrium points in risk propagation,delves into the constructive role of government intervention in disrupting the proliferation of supply chain risks,and furnishes a macro-level analysis of the mechanisms governing risk propagation within supply chains and the accompanying intervention strategies,ultimately offering directives for government risk management.Both theoretical research and simulation experiments concur in affirming that,through the manipulation of the basic reproduction number,the government can effectively curtail the further expansion and diffusion of risks,thereby attaining the objective of risk containment.关键词
