突发事件经常导致需求扰动,致使供应链运营出现失调.以两条竞争供应链组成的供应链系统为研究对象,建立了供应链竞争基准模型.引入偏差惩罚成本,构建了竞争供应链应对单链需求扰动的均衡模型,给出了不同扰动程度下生产数量及零售价格的应对策略.研究发现,在一定的扰动程度内,原生产计划都具有鲁棒性,鲁棒性范围依赖于价格交叉弹性系数和偏离惩罚成本,其大小与需求扰动源无关.
Sudden events often lead to the disturbance of demand, which leads to the disorder of supply chain operation.Taking the supply chain system composed of two competing supply chains as the research object, the supply chain competition benchmarking model is established.Due to the deviation penalty cost, a competitive supply chain response list The equilibrium model of chain demand perturbation is given and the coping strategies of production quantity and retail price under different disturbance degree are given.The research shows that the original production plan is robust within a certain degree of disturbance and the scope of robustness depends on the price cross Elasticity coefficient and deviation from the penalty cost, the size of the demand perturbation source has nothing to do.
