摘要: 针对定制客运中乘降点与车辆路线分步优化导致的效率损失问题,本文提出一种动态乘降点与车辆路线联合优化的方法。首先,构建多目标联合优化模型,以最小化乘客出行成本、最大化企业运营效益为目标,在约束中限定乘客需求点仅能通过接驳或车辆路线进行连接,并引入多车型容量限制,同步优化乘客上下车时空安排与车辆服务计划;然后,设计一种混合启发式算法,以NSGA-III(Non-dominated Sorting Genetic Algorithm III)为框架,融合差分进化和自适应大邻域搜索,协同实现全局探索与局部精修;此外,同时集成ST-DBSCAN(Spatial-Temporal Density-Based Spatial Clustering of Applications with Noise)算法,从需求点中识别动态乘降点并引导种群进化;最后,以重庆主城至铜梁区为例进行验证。结果表明:所构建的联合优化模型能在不同需求规模下自适应选择最优车型配置,并协同优化服务效率与运营效益;所提算法能表现出更优的收敛性能与解集分布质量。实际运营中,联合优化使乘客平均接驳距离大约降低至未联合优化的1/10,单次运营利润增加31.62元,载客率提升2.77%。

Abstract: This paper addresses the efficiency loss in customized passenger transport caused by the separate optimization of passenger stops and vehicle routes and proposes a joint optimization method for dynamic ride and drop-off site and vehicle routing. A multi-objective optimization model is developed to minimize passenger travel costs while maximizing operational benefits, under the constraint that passenger demand points must be connected either via feeder services or direct vehicle routes. The model incorporates multi-vehicle type capacity limits and simultaneously optimizes passenger ride and drop-off schedules and vehicle service plans. A hybrid metaheuristic algorithm is designed using the NSGA-III (Non-dominated Sorting Genetic Algorithm III) framework, integrating DE and ALNS to achieve coordinated global exploration and local refinement. The ST-DBSCAN (Spatial Temporal Density-Based Spatial Clustering of Applications with Noise) is used to identify dynamic stops from demand points and guide population evolution. The case study of the Chongqing-Tongliang corridor shows that the model adaptively selects optimal vehicle fleets across demand levels while boosting both service efficiency and operational profit, with the algorithm exhibiting superior convergence and solution diversity. Practically, it could reduce the average passenger transfer distance to roughly one tenth that of non-joint optimization, and increase the single-trip profit by 31.62 yuan and the vehicle load rate by 2.77 percentage points.
