摘要
为了解决物流节点动态服务范围划分及其连续型物流节点协调布局问题,建立基于引力模型的物流节点服务范围划分模型,引入加权Voronoi图及其实现的离散生成法,实现复杂区域物流系统动态服务范围的精确划分,在此基础上,构建区域物流节点协调布局优化模型,结合最大空心圆策略和模拟退火算法提出模型的高效求解算法.
To solve logistics node dynamic service range division and continuous logistics node layout optimizationl,the paper established logistics node dynamic service range division model based on the gravitational model,then weighted Voronoi diagram and the discrete generation algorithm were introduced.Based on precise service range division,regional logistics node layout optimization model is built.Then,evolutional algorithm was adopted to realize the layout optimization of complex logistics system based on the largest circular hollow positioning strategy and simulated annealing algorithm.From practical examples it was shown that the proposed method is able to meet the requirements of the logistics planning and operation,also can offer the reference to the decision making of administrative departments to the location,layout and operation rationalization of the logistics node.
