| 摘 要： | 灰色预测是一种对灰色系统进行白化的算法，该算法需要的信息少、通用性强、计算量小.针对粮食产量的预测问题，依据其历史数据，建立了基于灰色系统理论的时间序列预测模型，利用可信度p^0、关联度R、后验差比值C和小误差概率p等项指标检验了模型，证实了所建模型是可靠的，可行的.

| Abstract: | The grey prediction is a kind of whitening algorithm.It needs less information and caluclation.Based on the historical data,the grey system prediction model of the yield of grain is designed.The tested results show that by calculating some indexes such as reliability porelevance degree R,correlative value of posterior error C and micro-error probability p,the model of grey system theory for the grain yield prediction is examined and certified,which proves the model to be reliable and feasible. |
