假定在一个由一个供应商与一个零售商组成的供应链中,供应商向零售商提供单一产品且其补货提前期可以通过增加费用进行压缩,零售商的外部需求不确定和部分缺货可以补充,本文建立了供应链分散决策和集中情形下的库存模型,得出了包含最优提前期、订货批量、安全库存因子和生产批量等决策变量的最优解,并提出了买卖双方分担压缩提前期投入费用的策略。算例分析表明,单项费用分担策略虽然能够使提前期压缩到与供应链集中决策时的情形一致,并实现供应链帕累托优化,但无法实现供应链整体最优化。
Suppose that in a supply chain consisting of one supplier and one retailer, the supplier provides a single product to the retailer and its replenishment lead time can be reduced by adding expenses. The external demand of the retailer is uncertain and part of the stock may be out of stock In addition, this paper establishes a decentralized supply chain decision-making and centralized inventory model, and obtains the optimal solution including decision-making variables such as optimal lead time, order quantity, safety stock factor and production lot, and puts forward that the buyer and the seller share the compression Tactics to spend in advance. The case study shows that although the individual cost sharing strategy can reduce the lead time to be consistent with the centralized decision of the supply chain and achieve the Pareto optimization of the supply chain, the overall supply chain optimization can not be achieved.
