军地一体化应急物资的连续型需求研究
Analysis on the Demand for Continuous Emergency Supplies of Military-Civilian Emergency Logistics Integration
-
摘要:为更好地解决军地一体化应急物流管理中连续型物资需求的配送问题,需要从物资的配送能力和需求紧迫性两方面进行分析。基于物流场理论,根据我国现阶段军地应急物资的双重管理模式,建立应急救援多配送中心物流场模型。在模型中将应急物资的配送和需求问题视为带正、负电荷的电场,其中正、负电荷分别代表配送中心和需要救援的区域,电荷数值大小分别代表配送能力的强弱及物流需求的紧急程度,并分析了单中心覆盖、多中心部分覆盖及多中心全部覆盖三种不同配送情况下应急物资的配送及与需求之间的联系。研究表明:配送能力、需求紧迫性及路网阻尼性等因素对连续型物资配送有着非常重要的影响,可为各配送中心分配适当配送量,提高运送时效性及降低任务分配的盲目性。Abstract:To better address needs for continuous emergency supplies problems among integration of military and local government emergency logistics management, delivery capabilities and urgent needs of emergency supplies are both need analyzed. Based on logistics field theory, the emergency rescue logistics field model of multi-distribution centers is set up according to China's current dual management mode of emergency supplies. The distribution and demand issues of emergency supplies are regarded as the electric field with the positive and negative charges in the model. The positive and negative charges are respectively represented the distribution centers and rescue areas, and their values represent the distribution capacity and the urgency magnitude of the needs. The link between distribution and demand is analyzed with three different emergency supplies distribution cases of the single center covering, multi-centers partially covering and multi-centers full covering. Studies show that distribution capacity, demand urgency, damping of road networks and other factors has very important influence on the continuous type of material distribution, and allocate adequate distribution for distribution centers to improve transportation timeliness and reduce blind assignment.
