摘要
针对新型公交服务产品如高铁快巴仍然缺少相应的运营方式的情况,对高铁快巴的车辆调度与人员排班的综合优化问题进行研究。为发挥高铁快巴灵活性的优势,引入了满足司乘人员工作时间要求的时间窗约束,建立了考虑司乘人员时间窗的高铁快巴车辆调度与人员排班综合优化模型。通过算例计算,得到了高铁快巴的最优调度与排班方案。结果表明,相比于传统的多线调度独立优化,在高铁快巴的优化问题上使用综合模型的效果更好,综合优化后运营成本比原运营方案降低约8.98%、比独立优化降低约4.73%,同时减少了司乘人员数量,验证了该模型在解决高铁快巴问题上的正确性与良好应用效果。
In this study,the integrated vehicle and crew scheduling problem of express buses on high-speed railways is studied owing to the lack of appropriate operational approaches for this new type of public transport service product.To benefit from the flexibility of express buses for high-speed railways,the work-time window constraint is introduced to meet the work-time requirements of the crew.An integrating optimization model for vehicle and crew scheduling is built.Then,the optimal vehicle and crew scheduling program is validated with real-time examples.Results show that this integrated optimization model is better than the traditional multiple route optimize independently.Operating costs are reduced by approximately 8.98%compared with the original operation schedule and approximately 4.73%compares with the independent optimization using this integrated optimization model,while the number of crew is also reduced.Furthermore,the accuracy and the satisfactory results of the model in solving the integrated vehicle and crew scheduling problem of express buses for high-speed railway are verified herein.
