考虑保质期的两级供应链MTS-MTO提前期优化研究

Lead time optimization of MTS-MTO in two-echelon supply chain considering shelf life

在具有保质期特性的快消品行业中,供应商在面向订单(MTO)生产策略下较长的订货提前期会给零售商带来高库存以及高运作成本,削弱供应链的快速响应能力.对比原来的MTO生产策略,提出一种面向库存-面向订单(MTS-MTO)混合生产策略.首先,基于产品保质期的特点建立MTO生产策略下的供应链成本模型,并给出供应链成本最优的经济订货批量;其次,根据MTO求出的最优经济订货批量,建立MTS-MTO生产策略下的供应链成本模型,并确定供应商的应持有库存M,求出供应商在MTS-MTO生产时的充要条件,为供应链决策提供依据;再次,给出一种基于满意度的Nash协商模型以确定零售商应给予供应商的补偿H;最后,通过数值分析验证并讨论符合MTS-MTO生产的产品特征.

In the fast moving consumer goods(FMCG) industry with short product’s shelf life, the original MTO strategy brings high inventory and operating costs to the retailer because of its longer order leader time, therfore, a make to stock-make to order(MTS-MTO) strategy is proposed. Firstly, based on the characteristics of product shelf life, the supply chain cost model of the MTO production strategy is established, and the economic order quantity of the supply chain with optimal cost is given. Then, according to the optimal economic order quantity obtained using the MTO strategy,the supply chain cost model under the MTS-MTO production strategy is established. Besides, the supplier’s inventory M is determined. Necessary and sufficient condition is also provided for the supply chain decision. A Nash negotiation model based on satisfaction is given to determine the compensation H that the retailer should give to the supplier. Finally,the product characteristics under the MTS-MTO hybrid production strategy are verified and discussed through numerical analysis.
