一类灰色投入产出优化模型的设计与应用

THE DESIGNING AND APPLICATION OF AN OPTIMAL GREY INPUT-OUTPUT MODELS

本文提出一类投入产出优化预测技术,通过对所获信息不断的有效利用,可以将投入产出模型中的灰参数逐次加以修正,使模型不断得到改进,从而提高预测的精度。应用实例表明,应用该优化模型可以取得比较满意的结果。

In this paper,a technique of optimal grey input-output model is proposed. The grey parameters in a input-output model can be successively modified here by efficient utilization of information,This is an improvement on the model so that the accuracy of forecasting model can be increased.Application shows that the optimal models is capable of giving satisfactory results.
