摘要:以赈灾物资市场筹集系统的可靠性问题为研究对象,在分析赈灾物资市场筹集系统基本特征的基础上,首先提出了有利于系统可靠度提高的串-并联逻辑结构;然后就系统在规定时间受物流量或成本约束下寻求串-并联系统各构成单元和整个系统的最优可靠度;最后在综合考虑分配单元的重要度与复杂度基础上,对初次优化后不满足预期可靠度指标的系统单元进行了再次优化,达到进一步优化系统可靠性的目的。

Abstract:In this paper, the goal of the research is the reliability problems of market collection system of disaster relief materials, through analyzing the basic characteristics of market collection system of disaster relief materials. First of all, it proposed the seriesparallel logical structure that was advantageous to enhance reliability of the system; And then, in scheduled time, researched the reliability of each unit of seriesparallel system and the whole system under logistics flow or cost constraints; Finally, in considering the allocation unit of importance and complexity, it is expected that reliable indicators of the system units was not qualified to base on initial optimization and optimized again to achieve the objective of optimized system reliability.
Key words:disaster relief materials; market collection; system reliability; optimization and distribution
赈灾物资市场筹集是应急物资保障的重要环节,面对大规模突发自然灾害,在国家战略储备、社会捐赠和紧急征用等途径所筹集的赈灾物资出现不足时,政府必须依法采取紧急采购或组织突击研制和生产等市场筹集措施,以确保在紧急状态下赈灾物资的及时供给,最大限度地满足紧急救援对物资的需求[1]。因此赈灾物资市场筹集的优劣直接关系到救灾物资保障水平和应急物流目标的实现[2],为达到赈灾物资市场筹集在时间、成本和空间效益上的最优化,需及时建立可靠性高、运行稳定的赈灾物资市场筹集系统,以加强企业、部门、区域等主体之间的协调和各类资源的高效利用,确保赈灾物资市场筹集目标的实现。
在赈灾物资筹集研究方面,Trevor Hale和Christopher R Moberg[3]主要研究了应急物流供应节点的选择,特别是针对节点应急物资存储量的多少建立了定量模型;……
