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.
