烟草工业企业多级库存协同控制模型研究

为实现工业企业高架库库容有效利用、发运库高效运作状态，减少移库成本，通过应用ABC分类法，将发运库卷烟分成三类并设定不同的内部存销比，根据存销比、日发运需求和库容量识别细分出三种不同移库需求，并生成多套不同的移库策略，建立了基于高架库、中转库、发运库三级仓储体系的内部库存控制模型。实证表明:（1）高架库库容利用率由75.2%提升至了82.3%，（2）发运库库存周转次数由20.12次/年提高至22.24次/年，（3）单位移库成本则由3.75元/件降低至3.31元/件。结果证明了该模型在工业企业内部库存控制应用的有效性。 

Research on multi-echelon coordinated inventory control model of tobacco industry enterprises

In order to realize the efficient utilization of pallet warehouse storage capacity of industrial enterprises and the efficient operation of the dispatch warehouses, and to reduce the cost of warehouse shifting, the cigarettes in the delivery warehouse are divided into three categories using ABC classification method and assigned with different internal stock-sales ratios. According to the stock-sales ratio, daily shipping demand and storage capacity, three different demands for dispatch are identified and subdivided, and several different strategies for dispatch are generated. An internal inventory control model based on the three-level storage system of pallet warehouse, transfer warehouse and delivery warehouse is established. The empirical results showed that: (1) the utilization ratio of pallet warehouse capacity increased from 75.2% to 82.3%, (2) Inventory turnover increased from 20.12 times per year to 22.24 times per year, (3) the unit cost of warehouse shifting decreased from 3.75 yuan per unit to 3.31 yuan per unit. The proposed model is proved to be effective in internal inventory control of industrial enterprises.
