摘要
该文探讨了在应急物资保障过程中,如何有效解决初期末端物资供应不足和后期物资库存过剩的问题.通过分析应急物资保障过程中的相关因素,运用先分解后耦合的系统工程法构建了应急物资协同储备系统动力学模型.以中国西南地区某省为例,模拟应对较大规模地震灾害的情况,利用Vemsin PLE软件对模型进行分析,得到优化方案.研究表明:①加大末端物资储备量,尤其是交通不便地区,能有效应对前期物资需求;②通过调整末端与上级的期望物资使用天数,可大幅减少物资总库存量,提高经济性;③降低物资总库存量能减小库存波动幅度,增强物资供应链路的稳定性.通过上述分析,为优化应急物资储备模式提供了参考,有助于提升应急管理的效率和效果.
Abstract
In this article,two issues are discussed concerning insufficient supply of end of pipe materials in the early stage and redundant total inventory of materials in the later stage of emergency material support.By analyzing the relevant factors in the emergency material support process,a dynamic model of the emergency material collaborative reserve system is constructed using the system engineering method of decomposition first and coupling later.Taking a province in southwest-ern China as an example,a simulation is conducted to cope with a large-scale earthquake.Using Vemsin PLE software analysis,optimization plans are proposed to increase end of pipe inventory and shorten the expected usage days of higher-level materials.Results show that:①Increasing the reserve of end of pipe materials,especially in areas with inconvenient transportation,can effectively meet the demand for materials in the early stage;②By adjusting the expected usage days of materials at the end and higher levels,the total inventory of materials can be significantly reduced and the economy can be improved;③Reducing the total inventory of materials can reduce inventory fluctuations and enhance the stability of the ma-terial supply chain.The above analysis provides reference for optimizing the emergency material reserve mode.
