基于物流场原理的北煤南运水运网络优化

根据物流场运行的基本原理，将我国“北煤南运”产地、港口、铁路、水运等要素与物流源、物流汇、物流节点、物流通道各要素相结合，依据物流场模型，建立我国“北煤南运”运输网络模型，对现有运输网络进行优化，实现运输利益最大化。结合实际中的“北煤南运”案例进行分析，验证模型的适用性，并对我国现有的煤炭水运网络进行分析。

North-to-south coal diversion water-transport network based on logistics field theory

According to the operation mechanism of the logistics field, we combine the factors of the North-to-South coal diversion, such as production place, ports, railways and water transports, with the logistics sources, sinks, corridors and nodes. On the basis of the logistics field operation model, we build the North-to-South coal diversion transport network in China and optimize the existing transport network, so as to realize the maximum benefits. Moreover, we analyze the actual South-to-North coal diversion cases to verify the applicability of the model and analyze the existing water network of the coal in China.
