文中分析了基于现有的引力模型计算物流园区辐射范围的缺陷,然后基于雷利法则给出了改进引力模型,并对物流园区辐射力进行定义。最后根据改进引力模型确定物流园区的辐射范围。

英文摘要：

This paper firstly analyzes the defects of using existing gravity model to calculate the radiation range of logistics center.Then,based on Reilly’s Law,we propose a improved gravity model,and the definition of logistics center’s radial force.Finally,we determine the radiation range of logistics center according to the developed gravity model,and we also present different developing strategies for logistics center under different radiation range.
