基于ArcGIS的多温区冷藏车辆路径优化

Route optimization of multi-temperature refrigerated vehicles based on ArcGIS

为降低冷链物流成本,研究多温共配模式下生鲜农产品冷链配送问题。采用多温区冷藏车,构建考虑运输成本、货损成本、制冷成本的路径优化模型,利用遗传算法对算例进行求解,借助ArcGIS规划最短路径。算例结果显示,与传统配送模式相比,多温共配模式可减少2辆冷藏车的调度,总成本降低34. 1%,实际运输距离缩短54. 1%。多温共配模式可有效解决生鲜农产品配送小批量、多品种、高成本的问题。

In order to reduce the cost of cold chain logistics,the cold chain distribution of fresh agricultural products under the multi-temperature joint distribution mode is researched. The multi-temperature refrigerated vehicles are used,and the route optimization model considering transportation cost,damage cost and refrigeration cost is constructed. The example is solved by the genetic algorithm,and the shortest path is programmed by ArcGIS. The result of an example shows that: compared with the traditional distribution mode,the multi-temperature joint distribution mode can reduce the scheduling of 2 refrigerated vehicle,the total cost by 34. 1% and the actual transportation distance by 54. 1%. The multi-temperature joint distribution mode can effectively solve the problem of small batch,multiple species and high cost of fresh agricultural product distribution.
