为提高长江航运散货运输能力,对其运输组织方式进行了优化及其船型论证.在预测长江流域2020年散货运输货运量及流向的基础上,确定了主要货物种类及其典型航线,建立了长江散货运输组织方式多指标综合测算模型体系.采用多准则评判方法,基于典型航线分航段论证思想,对长江散货运输组织方式进行了多方案优化及多目标综合评判,获得了长江主要干散货运输组织方式及最佳运输船型.研究结果表明:最佳运输船型具有较高的装载率及年货运量,在分航段运输中能够取得较好的经济效益.该结果为制定长江流域散货运输水运发展规划提供了参考.
In order to improve the capacity of shipping the bulk cargo in the Yangtze River, the paper optimized its transport organization and its model verification.On the basis of forecasting the volume and flow of bulk cargo transported in the Yangtze River Basin in 2020, the main cargo types and their typical routes were established and established The multi-index comprehensive evaluation model system of Yangtze bulk cargo transport organization mode was adopted.Multi-criteria evaluation method was used to carry out multi-program optimization and multi-objective comprehensive evaluation of Yangtze River bulk cargo transport organization based on the idea of typical airline sub-segment argumentation, The main dry bulk shipping organization and the best shipping model.The results show that the best shipping model has a higher loading rate and annual cargo throughput and can achieve better economic benefits in the sub-shipping segment.This result is for the formulation The Yangtze River Basin bulk cargo transport water transport development planning provides a reference.
