摘要:

在本文中,我们制定了一个最优的订货策略作为一个随机控制问题,每个企业决定的投入量的基础上,从他们的上游供应商的库存量的输出好。为此,我们提供了一个封闭的形式的解决方案,为给定的固定生产策略的最佳要求的原材料。我们实施建议的政策上的15个公司的非循环网络的基础上,一个真正的产品供应链。我们首先模拟理想的需求情况,然后实施需求方冲击(即,需求水平超出政策制定考虑的范围)和供应方冲击(即,一些供应商停产),以评估拟议政策的稳健性。

英文摘要:

In this paper, we formulate an optimal ordering policy as a stochastic control problem where each firm decides the amount of input goods to order from their upstream suppliers based on the current inventory level of its output good. For this purpose, we provide a closed-form solution for the optimal request of the raw materials for given a fixed production policy. We implement the proposed policy on a 15-firm acyclic network based on a real product supply chain. We first simulate ideal demand situations, and then we implement demand-side shocks (i.e., demand levels outside of those considered in the policy formulation) and supply-side shocks (i.e., halts in production for some suppliers) to evaluate the robustness of the proposed policies.
