摘要
针对现有物流园区功能发挥不足的问题,依据物流网络系统特点,提出以区位优势为依托,以经济关联为核心的网络优化方法.为此,以图论方法确定结点的区位优势,以模糊规划方法确定多目标效益优势,构造了图—FUZZY相结合的物流网络优化模型,同时归结为简捷的0-1整数规划求解,并用物流网络工程实例检证其有效可行性.
Considering the insufficient performance of existing logistics districts functions, this paper proposes a optimization methed of the logistics structure based on the theory of location advantage and economic relationship. The location advantage determined using the graphs theory, and the benefit superiority of targets determined using the fuzzy theory. Then the logistic network optimization model is set up conjoined with graph theoryFUZZY logic, and finally come down to 0-1 integer programming. The feasibility of the model is proved by an instance of logistics network.
