提前期可控的二级供应链库存模型

Two-echelon Supply Chain Inventory Model with Controllable Lead Time

针对单个生厂商单个销售商组成的二级供应链系统,当生厂商采取批量生产等量运输策略时,假定提前期可控且可通过追加成本缩短提前期,建立了一个拥有不同再订购点的一体化随机库存模型.最后给出求解模型最优解的迭代算法,并以实例验证模型和算法的有效性.

A two-echelon supply chain consisting of a single-vendor and a single-buyer is considered in this paper.In the system under study,a vendor produces a product in a batch production environment and delivers the lot to the buyer with a number of equal-sized batches.Also,buyer＇ s lead time is controllable which can be shortened at an added cost.An integrated stochastic inventory model with different reorder points is proposed and then,an iterative procedure is developed to obtain the optimal solution of this proposed model.Finally,numerical examples are given to illustrate the validity of the model and algorithm.
