For the lack of return data in the first stage, the GM(1,1) model improving the generation method of neighborhood system is adopted, and forecasting is carried out by only using a few data. When the data amount reaches 50, the hidden quantitative relationship between sale quantity and return quantity is established by performing the transfer function-noise model. Its parameters are determined through model identification, parameters estimation and diagnostic checking. Then, forecasting return is accomplished.

回收初期数据缺乏，采用改进邻域系生成方法的GM(1，1)模型，实现了少量数据情况下的预测；回收数据累积到50个后，利用传递函数噪声模型构建了回收量和前期销售量之间的内在数量关系式，然后通过模型识别、参数估计、诊断检验确定了关系式的具体参数，进而实现了回收预测。
