【摘要】：近些年,京津冀区域物流业迎来了高速发展时期,区域物流基础设施也日趋完善,但仍存在区域物流运输成本过高的问题,究其原因,是由于区域物流网络缺乏统一规划。因此,本文基于轴辐式理论开展对于京津冀区域物流网络的优化研究,为区域物流网络的合理规划布局提供理论依据支撑,以期解决区域物流业发展过程中所出现的问题。首先,本文对区域现有物流网络进行了描述,利用点强度、簇系数、点相关性等测度指标对其进行了网络结构特征分析,并在此基础上,分析总结了京津冀区域现有物流网络中存在的问题;其次,构建包含4项一级指标及12项二级指标的评价体系,选用因子分析法对京津冀区域物流节点进行综合评价,并依据评价结果选取备选枢纽节点;最后,构建区域物流网络优化模型,设计遗传算法作为其求解算法,以京津冀区域物流网络为实例开展优化研究,得出优化后的京津冀区域物流网络布局方案。从优化结果来看,顺义、武清、石家庄、唐山、沧州五地被选为轴辐式区域物流网络的枢纽节点;优化后的区域物流网络在物流总成本、运输模式结构等方面优化效果显著;所选定的五个枢纽节点分布合理,辐射范围互有补充,可以形成覆盖京津冀区域的枢纽布局形式。论文的研究成果在推动京津冀区域物流网络合理布局规划、降低区域物流运输成本等方面具有一定的现实指导意义。
[Abstract]:In recent years, the regional logistics industry of Beijing-Tianjin-Hebei has ushered in a period of rapid development, and the regional logistics infrastructure has become more and more perfect, but there is still the problem that the transportation cost of regional logistics is too high, which is due to the lack of unified planning of the regional logistics network. Therefore, based on the axis-spoke theory, this paper studies the optimization of the regional logistics network in Beijing, Tianjin and Hebei, and provides the theoretical basis for the rational planning and layout of the regional logistics network, in order to solve the problems in the development of regional logistics industry. First of all, this paper describes the existing logistics network in the region, and analyzes the network structure characteristics by using the measurement indexes such as point strength, cluster coefficient, point correlation and so on. The problems existing in the existing logistics network of Beijing-Tianjin-Hebei region are analyzed and summarized. Secondly, an evaluation system consisting of 4 first-grade indexes and 12 second-class indexes is constructed, and a comprehensive evaluation of the logistics nodes in the Beijing-Tianjin-Hebei region is carried out by using factor analysis method. Finally, the optimization model of regional logistics network is constructed, genetic algorithm is designed as its solution algorithm, and the optimization research is carried out with the example of Beijing-Tianjin-Hebei regional logistics network. After the optimization of the Beijing, Tianjin and Hebei regional logistics network layout. From the optimization results, Shunyi, Wuqing, Shijiazhuang, Tangshan and Cangzhou are selected as hub nodes of the regional logistics network, and the optimized regional logistics network has remarkable effect in the aspects of total logistics cost, transportation mode structure and so on. The distribution of the five nodes is reasonable and the radiation range is complementary to each other, which can form the layout of the hub covering the Beijing-Tianjin-Hebei region. The research results of this paper have certain practical significance in promoting the rational layout planning of Beijing, Tianjin and Hebei regional logistics network and reducing the transportation cost of regional logistics.
