【摘要】：针对由多个制造商和多个零售商构成的供应链网络,利用含参数的变分不等式建立了具有需求扰动的供应链网络均衡模型。首先,利用变分不等式的方法建立了需求扰动前供应链网络的均衡模型,通过该模型分析说明了供应链内部成员如何确定均衡的生产、订购和销售计划。进一步,当该均衡计划在执行过程中需求发生扰动后,利用含参数的变分不等式的方法建立了供应链网络的扰动模型,说明了供应链内部成员如何在考虑收益以及偏离成本的情况下确定新的生产、订购和销售计划,并证明了含参数变分不等式解的连续性。最后,利用数值算例说明了模型的有效性,并发现供应链环境下需求扰动的扩散性。
[Abstract]:For the supply chain network composed of multiple manufacturers and retailers, a supply chain network equilibrium model with demand disturbance is established by using variational inequalities with parameters. Firstly, the equilibrium model of supply chain network before demand disturbance is established by using variational inequality method. Through the analysis of the model, how to determine the balanced production, order and sales plan of the members in the supply chain is explained. Furthermore, when the demand of the equilibrium plan is disturbed during the execution, the perturbation model of the supply chain network is established by means of variational inequalities with parameters. This paper explains how the members of the supply chain determine the new production, order and sales plan under the consideration of profit and deviation cost, and proves the continuity of the solution of variational inequalities with parameters. Finally, numerical examples are used to illustrate the validity of the model and the diffusivity of demand disturbance in supply chain environment is found.
