摘要
给出了描述非对称指数型模糊数近似程度的贴近度的定义及其表达式;在此基础上建立了输入、输出为模糊数,系数为精确数的模糊多元回归模型,并应用该模型对山东南部农田鼠害夏峰期发生率进行了预测,结果与实际情况比较吻合.
Expressions are given to describe the closeness between the estimated value and observed value for two asymmetric exponential fuzzy numbers. Based on that~ the model is given to solve the question of fuzzy multivariable regression with fuzzy input,fuzzy output and crisp coefficients. Finally,using this model, the prediction of field mouse occurrence rate have been done and satisfied result is obtained.
