山东省港口经济腹地计算方法的研究

On Computing Method of Economic Hinterlands in Shandong Harbours

提出了采用O—D物流与图论结合计算沿海港口经济腹地的方法,计算了山东省各港口的经济腹地并对各港口的吞吐量进行了预测,与实际的吞吐量进行了对比。对公路、铁路混合路径最短路的计算和复杂的非线性网络货物布局的优化也提出了相应的计算方法。

This article presents an approach to calculating the economic hinterlands in coastal harbours by using the combination of the O-D logistics and the graphic demonstrations,computes the economic hinterlands in all the harbours of Shandong province,predicts the handling capacity of all the harbours and contrasts with the real handling capacity. It also proposes the computing method of the shortest distance of the blend route of the highway and the railway and the optimum method of the layout of the complicated nonlinear network cargoes.
