在本文中，我们建立了一个由制造商和零售商组成的供应链网络模型，其中与零售网点相关的需求是随机的。我们建立了各种决策者的优化行为模型，推导了均衡条件，并建立了有限维变分不等式公式。我们从存在唯一性结果方面给出了平衡模式的定性性质，并建立了所提出的计算过程收敛的保证条件。最后，我们通过计算均衡价格和产品出货量的几个数值例子来说明该模型。这是第一个对随机需求的供应链网络均衡模型进行建模、定性分析和计算的结果。(C) 2003 Elsevier B.V.版权所有
In this paper, we develop a supply chain network model consisting of manufacturers and retailers in which the demands associated with the retail outlets are random. We model the optimizing behavior of the various decision-makers, derive the equilibrium conditions, and establish the finite-dimensional variational inequality formulation. We provide qualitative properties of the equilibrium pattern in terms of existence and uniqueness results and also establish conditions under which the proposed computational procedure is guaranteed to converge. Finally, we illustrate the model through several numerical examples for which the equilibrium prices and product shipments are computed. This is the first supply chain network equilibrium model with random demands for which modeling, qualitative analysis, and computational results have been obtained. (C) 2003 Elsevier B.V.
