多货种O－D分布模型及其应用

A Study On Forecasting Model of Multi-goods O-D Distribution

在已有成果──“用户最优Ｏ－Ｄ分布模型”的基础上，进一步研究了预测多个货种Ｏ－Ｄ分布的模型──“半比多阶段分布模型”并将这一模型应用于江苏省２０００年航运的矿建、煤炭及其它三个货种的Ｏ－Ｄ分布预测，结果肯定了模型的可行性。

his paper deals with the multi-goods O-D distribution model“the half ratio multi- stage distribution model”on the basis of“O-D distribution of user optimization”. This paper also predicts Jiangsu Province's shipping O-D distribution for the year of 2000 concerning mineral goods,coal and other goods with the present model.The results confirm the feasibility of the model.
