重大灾害后应急物资调配模糊优化研究

摘要

The paper analyzed the characteristics of the distribution of emergency material and the difference between the emergency logistical and normal logistic on the basis of domestic and foreign scholars＇ studies,It established a multi-objective fuzzy linear model which based on the main objective with the shortest transit time and the second objective with the minimize transportation costs and the constraints with the demands,traffic and transport capacity,It applied the fuzzy optimization method solve the model.Finally,Taking the three disaster towns in wenchuan earthquake as an example verified the model and the strategy in emergency supplies after the disaster,and analyzed the effects of deployment.%在总结国内外学者研究的基础上,分析了灾后应急物资调配的特点及和普通物资调配的区别,建立以运输时间最短为主要目标,以运输成本最小为第二目标,需求量、运输量以及运输能力为约束条件的多目标模糊线性规划模型,并利用模糊数排序指标模型简化并求解。最后以汶川地震中3个受灾乡镇应急物资调配为例进行实证分析,对灾后应急物资调配策略及模型进行了验证,并对调配效果进行了分析。
