【摘要】 由于社会高速发展而出现了许多新建城镇 ,对这些区域进行货运需求预测时 ,以前常用的许多方法很难实施或者因精度不高而无法得到满意的预测值 .因为缺乏基础资料 ,采用类比法又找不到合适的区域进行类比 ,所以尝试用灰色模型分行业对新建城镇进行货运需求预测 .采用此模型可望得到较满意的预测数据 ,节省了资料采集和数据处理的工作量更多还原

【Abstract】 Along with the developing of our society, there are a lot of new built towns appeared in our country. When forecasting the demands of freight in these districts, the ways formaly used cannot obtain satisfactory datum for the difficulties of putting in practice or poor precision. Because of the shortage of datum, and it is difficult to find a suitable district to adopt the way of analogy, Grey Model is adopted to forecast the demands of freight in these new built towns of each industries. Using this model satisifactory forecasted figures can be obtained, and a great mount of work load of datum collecting is decreased.更多还原
