摘    要:本文用模糊(Fuzzy)、灰色(Grey)、层次分析(Analystical Hierarchy Process缩写AHP)方法,简称FGA分析,确定各因素的权重系数,构成Fuzzy向量X,与列联比构成的Fuzzy矩阵R,进行模糊关系合成,以Y=X。R数学模型,预测二代玉米螟危害程度,经21年资料检验,回报准确率均达100%。通过贴近度分析,最后抉择以专家估测Y=X_F_1。R为最优综合评估法。这有助于解决专家系统和人工智能系统获取知识的难题。

关 键 词:模糊  灰色  层次分析  预测  危害程度

FORECASTING HARM DEGREE OF THE SECOND GENERATION OF EUROPEAN MAIZE BORER BY FGA ANALYSIS
Abstract:The weight coefficients of every factor are determined by the methods of Fuzzy,Grey and Analystical Hierarchy Process(FGA),composing the Fuzzy vectors X The Fuzzy matrix R is made up by contingency rate.Fuzzy relation composition is operated between X and R.The harm degree of second generation European maize borer is forecasted by mathematical model-Y=X·R.In spection of 21year data reveals that their historical coincidences all reach 100%.After closeness degree analysis,finally the expert reckoning Y = X_((F)_1)·R is chosen as a method of the most advantageous comprehensive evaluation.This helps to solve a hard problem to gain knowledge via expert system,artificial intelligence and ability system.
Keywords:Fuzzy  Grey  Analystical Hierarchy process  forecasting  harm degree
