随机需求下供应链库存风险分担模型研究

Abstract

本文主要研究了随机需求下两阶段供应链的库存风险分担问题,首先给出随机需求背景下的供应链库存分散决策模型,并以此为基准通过引入订货协调率和追加订货价格两个参数提出了随机需求风险下的库存风险分担模型,最后通过算例来说明库存风险分担模型在供应链库存协调中是有效的。

This article studied the inventory coordination of two-stage supply chain under stochastic demands.First,the decentralized decision model under random demands is proposed,then discusses the profit models of sharing inventory risk under adjustable quantity-rate and additional order price trategies in which the supplier partakes part of inventory risk.Finally,a numerical example illustrates that the inventory risk partaking strategy is valid in inventory coordination in supply chain.
