摘要: 针对横截面数据的复杂装备研制费用预测问题,研究了GM(0,N)模型的稳定性,证明了当样本较少时,GM(0,N)模型相对稳定。依据所提出的相似度对原始数据排序,在此基础上建立GM(0,N)模型,与待预测对象越相似的样本数据对GM(0,N)模型解的影响越敏感,从敏感性角度说明与待预测对象越相似的样本数据,其影响权重越大。由于相关因素相似的装备往往产生趋同的研制费用,充分利用与待预测对象相似的样本数据,有助于提高预测精度。通过实例说明了本模型的实用性与有效性。

Abstract: Complicated equipment development cost forecasting of the cross section data is studied, the GM(0, N) model is relatively stable when the sample is small. The data is sorted according to the similarity degree proposed, then GM(0,N) model is established, the more similar to the prediction the object sample data, the more sensitive to GM(0,N) model, the greater weight GM(0,N) model determine from the angle of sensitivity. Due to the similar equipment often produce similar development costs, making full use of the similar sample data to prediction object is helpful to improve the forecasting accuracy. The practical example is given to illustrate the practicability and validity of this model.
