Aiming at the practical problems of intermodal transport network planning in the hinterland of inland ports under the “dual-carbon” strategy,a mathematical model of intermodal transport hub location in the hinterland of inland river ports is proposed and a solution method is designed.The mathematical model is constructed with the objective of minimizing the enterprise transportation cost (including cargo transportation cost,transit cost and carbon emission cost) and hub operation cost (including fixed operation cost and renovation/expansion cost) during the planning period,and the solution method is designed based on the idea of “preliminary selection-preferred selection-optimization”.The method firstly determines the list of alternative hubs based on the results of gravity method;secondly,based on the indicators of site size,development space and service capacity,the AHP-TOPSIS method is used to select the hubs corresponding to the number of hubs at each stage and the number of hubs from the alternative hubs,and obtains the set of preferred hubs;lastly,the multimodal hub location mathematical model is used to obtain the final hub siting scheme.Taking a port group along an inland river as an example,the hub location under different decision preferences is determined.The results show that the proposed model and algorithm are convenient and reliable,and provide a systematic methodological tool for multimodal hub planning in the hinterland of inland waterways,which can help reduce logistics costs and promote the transformation of low-carbon logistics.
