摘要
应急物资储备是实施应急救援、提高反应速度的基础,是我国应急管理建设的重要内容。从库存价值变化的角度出发,建立应急物资库存成本最小化和期望效益最大化的动态储备模型,以实现低库存成本与高应急保障水平之间的动态平衡。该模型考虑了应急物资库存可能发生贬值或增值情况,以"先进先出"原则研究了库存物资周期性消耗和补给的过程,实现了同等保障水平下应急物资的社会效益,同时,可平衡储备物资在市场中的供需关系。
As a main component of emergency management and construction,the inventory of emergency materials provides a foundation for emergency rescue and improving the reaction speed. In order to achieve a dynamic balance between low inventory costs and efficient emergency security,this paper proposes a dynamic reserve model with minimizing inventory costs and maximizing social benefits in view of the inventory value change. Taking into account the depreciation or appreciation of the emergency materials,the model considers the process of inventory materials' consumption and supplement periodically based on the principle of " first in and first out",which guarantees the social benefits of emergency materials without sacrificing the emergency security. Meanwhile,it contributes to balancing the supply and demand of emergency materials in the market.
