摘要
医院药品对保质期和服务水平有非常高的要求,同时,药品的库存空间在医药库存中也有重要影响。首先针对快速失效的医药药品考虑了医药库存的合同保质期以及库存空间约束,同时考虑医院库存以及制造商库存,基于经济订货批量模型和经济生产批量模型建立了二级供应链的医药库存模型,然后用MATLAB软件求解了模型最优解,并对一些重要参数进行了敏感性分析。研究发现,合同保质期对医院订购批量、制造商生产批量和总库存成本有一定的影响,其中对于制造商的生产批量以及医院的库存成本影响较大。如果不考虑合同保质期的约束,将会对总库存成本带来更大损失。
Hospital drugs have strict requirements in shelf life, service level, and inventory space. Based on the classic Economic Order Quantity and Economic Production Quantity model, this paper first develops two-echelon Supply Chain inventory models of hospital and manufacturer for perishable drug considering shelf life and inventory space. The optimal solutions of the inventory model are obtained by using MATLAB. Sensitivity analysis of some key parameters is conducted. Then the conclusions are obtained. Drug shelf life has a certain effect on the ordering quantity of hospital, the production lots of manufacturer and total inventory cost. And it has a relatively large impact on the manufacturer＇s production lots and total inventory cost of hospital. Drug failure will bring greater losses to total inventory cost, if it doesn＇ t take shelf life into consideration. Finally the influence of shelf life to the inventory policy for perishable drugs is verified by the numerical analysis and the sensitivity analysis.
