九十年代我国进口铁矿石的海运分析

Ocean Transport Freight Rate Anaiysis of Chinese Imporation of Iron ore in the Nineties

本文对我国进口铁矿石作了预测和分析，并研究了铁矿石海运港口和运输船型的发展，在此基础上提出了以船舶吨位、航速和航距为参数的计算必要运费率（RFR）的数学模型，还对航速的选取作了探讨。最后针对一些不定因素对计算结果进行了分析。

Based on a prediction of the import quantities of iron ore and the development of har-bours and the transport ship types in the nineties, a mathematical model for the evaluation of Required Freight Rate (RFR) is set up in terms of ship's deadweight, service speedand voyage range. The selection of service speed and the sensitive analysis with regard tosome uncertain factors are also discussed.
