考虑风险和过期处理成本的危化品库存控制

Inventory Control of Hazardous Chemicals Considering Risk and Handling Cost

摘要: 在危化品零售企业，库存成本占企业物流成本的很大一部分。因此，如何有效的进行控制化学危险品库存已成了每个危险化学品企业不可避免的问题。本文在传统的(Q,R)模型中加入“风险成本”和“过期处理费用”建立符合危险品特性的库存控制模型，并对模型中各参数做出灵敏度分析。最后通过一个实例，应用matlab求解，验证了模型的实用性。

Abstract: Inventory costs account for a large portion of the logistics costs in hazardous chemicals retail en-terprises. Therefore, it has become an inevitable problem for every dangerous chemical company about how to control the inventory of chemical dangerous goods effectively. Based on the traditional (Q,R) model, the “risk cost” and “expiration processing cost” are added to establish an inventory control model that meets the characteristics of dangerous goods, and sensitivity analysis is performed on each parameter in the model. Finally, an example is given to verify the practicability of the model.
