高铁与公路物流联运的生鲜农产品路径规划

Routes Planning of Fresh Agricultural Products Based on Multimodal Transport Combining High-Speed Railway Logistics with Road Logistics

研究高铁物流与公路物流联运方式的生鲜农产品配送规划,综合考虑生鲜农产品产地的集货配送需求、产地与销地之间的高铁物流直接运输特性、销地的送货配送需求,以物流总成本最小为优化目标构建“公路 + 高铁 + 公路”物流联运的开放式车辆路径规划模型,根据模型特点设计一种三阶段启发式算法求解。实验结果表明本文模型与算法能有效规划高铁物流与公路物流联运方式的生鲜农产品配送路径,降低生鲜农产品物流成本,拓展生鲜农产品流通半径,确保生鲜农产品送达客户时的鲜活度。

The distribution planning of fresh agricultural products based on multimodal transport combining high-speed railway logistics with road logistics is considered in this paper. The open vehicle routing problem (OVRP) model of “road + high-speed railway + road” joint logistics transport is constructed with the goal of minimizing the total logistics cost based on the comprehensive consideration of the vehicle pick up the demand of fresh agricultural products producing areas, the direct transport characteristic of high-speed railway logistics between the producing areas and the selling areas, and the vehicle delivery demand of selling areas. According to the characteristics of the OVRP model, a three-stage heuristic algorithm is designed. The experimental results show that the OVRP model and algorithm can effectively plan the vehicle routes of fresh agricultural products under the multimodal transport combining high-speed railway logistics with road logistics, reduce the logistics cost of fresh agricultural products, expand the circulation radius of fresh agricultural products, and ensure the freshness of fresh agricultural products when they are delivered to customers.
