| 目的 针对农村地区运输困难问题，在“客货邮”融合背景下通过固定运输路线的农村公交和灵活运输的物流车辆，并考虑农村公交运输货物价格的不确定性，促进农村偏远地区物流运输环节的降本增效。方法 构建以最小化总成本为目标的农村公交−物流车辆协同运输决策模型。在此基础上，考虑农村公交运输价格的不确定性，采用多区间鲁棒优化方法构建鲁棒优化模型。在实验环节，使用cplex进行数值实验和现实案例分析。结果 通过农村客货邮协同运输决策能够有效降低运输成本，并提供了有效的解决方案。此外，公交运输价格的不确定性会带来整体成本的增长和农村公交使用率的减少。结论 结合农村客货邮运营实践，设计了协同运输决策模型及鲁棒优化模型，基于算例和案例，验证了所构建模型的合理性，能够为客货邮融合发展管理者提供有益的决策支持。 |

| In order to solve the transportation difficulties in remote rural areas, the work aims to promote cost reduction and efficiency of logistics and transport in remote rural areas by coordinating rural buses with fixed transportation routes and logistics vehicles with flexible transportation conditions and considering the uncertainty of the bus transportation price of goods in rural areas under the integration of "passenger, freight and postal service". A coordinated transportation decision model for rural buses and logistics vehicles with the objective of minimizing total costs was established. Based on the above, considering the uncertainty of rural bus transportation price, a robust decision model was constructed by a multi-interval robust optimization method, and an easily solvable robust equivalence model was obtained through duality theory. In experiment link, the CPLEX numerical experiment and the analysis of real cases were carried out. The coordinated transportation strategy of passenger, freight and postal service in rural areas could effectively reduce the transportation cost and provide effective schemes. In addition, the uncertainty of bus transportation price could lead to overall cost increase and decrease of bus usage rate in rural areas. Combined with the operation practice of passenger, freight and postal service in rural areas, the coordinated transportation decision model and robust optimization model are designed. The rationality of the models is verified by examples and cases, which can provide beneficial decision support for the managers in charge of the integrated development of passenger, freight and postal service. |
