年度、月度措施产量是多因素影响的灰色本征系统。根据灰色理论的基本原理提出措施产量的多项式预测模型、组合预测模型与GM(1.1)预测模型。文中对具有突变性单调或非单调的初始序列所建立的预测模型进行了多次残差修正与周期修正,使其预测误差在控制范围内。同时提出对定量预测模型进行定性调整,使之更符合实际。在实际计算中是多种预测模型的综合应用。该预测方法改变了过去仅凭经验预测措施产量的状况,具有科学性、实用性和可操作性。经实例计算证明是可行的。
年度、月度措施產量是多因素影響的灰色本徵繫統。根據灰色理論的基本原理提齣措施產量的多項式預測模型、組閤預測模型與GM(1.1)預測模型。文中對具有突變性單調或非單調的初始序列所建立的預測模型進行瞭多次殘差脩正與週期脩正,使其預測誤差在控製範圍內。同時提齣對定量預測模型進行定性調整,使之更符閤實際。在實際計算中是多種預測模型的綜閤應用。該預測方法改變瞭過去僅憑經驗預測措施產量的狀況,具有科學性、實用性和可操作性。經實例計算證明是可行的。

Annual and monthly measurement rate is the gray origi nal character systems influenced by multi-factor.Multinomial forecast model,ass embled forecast model and GM(1.1)forecast model of measurement rate is proposed according to the basic principle of gray theory.The established forecast model o f mutation monotone or nomonotone initial sequence adjusted by residual error am endment and period amendment several times.Fewer errors are found between the fo recast and true production.The quantificational forecast model is adjusted to ac cord with the reality of the comprehensive application of many types of models a t actual computation.The situation that forecasting measurement rate only relies on experience in the past is changed.It is a kind of scientific,practical and m aneuverable method and it has been proved to be feasible by actual examples.
