摘要
给出一个供应链多级库存随机模型,该模型以供应链总利润最大为目标,其中顾客需求、低层节点缺货量都是随机的。引入有效供应量的概念,以说明低层节点的随机缺货量对高层节点的影响。给出在一种特殊情况下模型的优化和分析,分析结果表明,是否考虑低层节点缺货量的不确定性,直接影响到优化模型的最优解。
A multi-echelon inventory stochastic model of supply chain was proposed, whose objective was to maximize the gross profit of supply chain. Customer＇s demand and short goods supplied by lower nodes were stochastic. To reflect the influence of stochastic quantity of short goods supplied by lower nodes on higher nodes, the concept of effective supply was introduced. Optimization method and analysis of model in a kind of special situation were provided. Result of analysis showed that model＇s optimal solution was affected by the uncertainty of short goods supplied by lower nodes.
