供应链中多种库存管理模式的比较

发布时间：2018-07-23 17:13

【摘要】：传统库存管理模式作为最先提出的一种管理模式存在着很多弊端,从而供应链管理下的库存管理模式诞生了,主要包括联合管理库存模式和供应商管理库存模式。本文在经济订货批量模型下,从成本方面对所提出的三种库存管理模式作了一个比较。首先结合三种库存管理模式的定义得出三种模式在经济订货批量模型下的特点。传统库存管理模式以优化零售商和供应商各自的成本为目的,得到零售商的最优经济订货批量和供应商的最优经济生产批量。供应商管理库存模式由供应商决定订货数量并承担零售商的库存成本和缺货成本,从优化供应链整体成本出发得到供应商的最优经济生产批量。联合管理库存模式通过设立联合库存中心代替供应商和零售商承担库存成本,以降低供应链整体成本为目的得到联合管理库存中心的最优经济订货批量。其次根据经济订货批量模型下三种库存管理模式的特点,分别从有提前期存在缺货以及无提前期不允许缺货两种假定出发推出他们的供应链成本公式。并且为了使比较更加直观,本文引用相关文章中的一组数据,根据推导出的供应链成本公式中的相关变量,建立灵敏度分析表并得到供应链成本变化图。通过对比供应链成本变化图,直观地得到不同假定以及不同模式下供应链成本的对比,同时证明了供应链管理下的库存管理模式的绝对优越性。在文章的最后是对整篇文章的总结以及对未来研究工作的展望。
[Abstract]:As one of the first management models, the traditional inventory management model has many drawbacks, so the inventory management model under the supply chain management is born, including the joint management inventory model and the supplier management inventory model. In this paper, three inventory management models are compared in terms of cost under the economic order batch model. Firstly, the characteristics of the three models under the economic order batch model are obtained by combining the definitions of the three inventory management modes. The traditional inventory management model aims at optimizing the cost of retailers and suppliers, and obtains the optimal economic order batch of retailers and the optimal economic production batch of suppliers. The supplier management inventory model is determined by the supplier and bears the retailer's inventory cost and the shortage cost. The optimal economic production batch is obtained from the optimization of the overall cost of the supply chain. The joint management inventory model obtains the optimal economic order volume of the joint management inventory center by setting up joint inventory center instead of suppliers and retailers to bear the inventory cost in order to reduce the overall cost of supply chain. Secondly, according to the characteristics of the three inventory management models under the economic order batch model, the supply chain cost formula is derived from the two assumptions that there is a shortage of goods with lead time and no shortage of goods with no lead time. In order to make the comparison more intuitionistic, this paper quotes a set of data from related articles, establishes the sensitivity analysis table and obtains the supply chain cost variation diagram according to the relevant variables in the derived supply chain cost formula. By comparing the supply chain cost change diagram, the comparison of supply chain cost under different hypotheses and different modes is obtained intuitively, and the absolute superiority of inventory management mode under supply chain management is proved at the same time. At the end of the article is the summary of the whole article and the prospect of future research work.
