摘要:

基于真实的物流场景,研究了带时间窗的多车型和多循环电动车辆路径问题。建立了一个基于路径的混合整数线性规划模型,可精确求解小规模算例。提出了将变邻域搜索算法和标签算法相结合的混合启发式算法,用以求解大规模情形。该算法提出了一种带随机因子的启发式算法构造初始解,并对时间窗和里程约束进行了松弛,使用邻域算子进行变邻域搜索,使用标签算法精确求解了固定商户配送顺序下的路径最优充电决策问题。测试结果表明:混合变邻域搜索算法可在极短时间内找到最优解,能大幅度降低物流成本。

Abstract:

Based on the real business practice, the multi-trip and heterogeneous-fleet electric vehicle routing problem (MTHF-EVRP) with time windows in green logistics is studied. A path-based mixed-integer linear model is built for the precise solution to the small-scale instances. A hybrid variable neighborhood search algorithm (Hybrid VNS) combined the variable neighborhood search algorithm with the labeling algorithm is proposed for the large-scale instances. The algorithm generates a modified insertion heuristic with random factor to construct the initial solution, allows the time window and range violation, adopts the neighborhood operators for the local search, and applies a labeling algorithm to solve the fixed-route recharging problem precisely. The methods are tested on the real-world benchmark instances for MTHF-EVRP. The results on the small-scale instances show that Hybrid VNS can find the optimal solutions in a very short time. Compared with the state-of-the-art algorithm on the large-scale instances, the algorithm can significantly reduce the logistics cost and the great competitiveness of Hybrid VNS is showed.
