【摘要】：为提高中欧班列运营效率,依据"一带一路"倡议下的中欧班列发展规划,以西部通道货源吸引区域为研究范围,以货源城市与目的地之间货物运输的总成本、时间和温室气体排放量最小化为目标,基于可持续发展理念构建了可持续联运枢纽配置模型。其中温室气体排放量由车辆在路径上和枢纽上消耗的温室气体排放量构成。根据货源城市到目的地的货运量、公路货运网络、铁路货运网络等参数,进行了联运枢纽选址和运输方式选择的决策。进一步采用改进多目标模拟退火算法进行了模型求解,并验证了算法的有效性。结果表明:在决策者选择偏好不同的情况下,多目标联运枢纽配置模型的解具有多样性;在不同目标权重选择下,改进的模拟退火算法能够搜索到模型的满意解,从而实现国际运输优化。
[Abstract]:In order to improve the operational efficiency of China-EU class train, according to the development plan of "Belt and Road" under the initiative of "Belt and Road", taking the area of attracting goods from the western corridor as the research scope, the total cost of goods transportation between the source city and the destination is taken as the research scope. Based on the concept of sustainable development, a sustainable intermodal transport hub configuration model is constructed for minimization of time and greenhouse gas emissions. The greenhouse gas emissions are composed of the greenhouse gas emissions consumed by the vehicle on the path and the hub. According to the freight volume from the source city to the destination, the road freight network, the railway freight network and other parameters, the decision of the location of the combined transport hub and the choice of the transportation mode are made. The improved multi-objective simulated annealing algorithm is used to solve the model, and the validity of the algorithm is verified. The results show that the solution of the multi-objective hub configuration model is diverse when the decision makers' preferences are different, and the improved simulated annealing algorithm can search the satisfactory solution of the model under different target weights. Thus, the optimization of international transportation is realized.
