摘要
针对工程中的非等时空距问题和原始数据序列发生转折性变化的情况 ,在非等间距 GM模型和灰色预测校正模型的基础上 ,建立了非等间距灰色预测校正模型。将该模型用于舰船柴油机光谱分析数据的趋势拟合和预测 ,结果表明该模型找到了准确的转折点 ,对变化后的趋势进行了正确的预测。
Unequal interval grey revised model was built based on unequal interval grey model and grey revised model,which is fit for the original series with unequal interval and sharp variations.The model built was used to fit and predict spectrometric analysis values of marine diesel engine.It is proved that the turning point is found and correct trend prediction after change is obtained by unequal interval grey revised model.
