In particular , some properties of the solution set of the equation a 0 x = b ( where " 0 " denotes sup - inf composition ) are given when the domain is an infinite set on lattice [ 0 , 1 ] . prom the coefficients of the equation aqx = 6 , it is showed that a sufficient and necessary condition that the solution set is nonempty and one for existence of an attainable solution or an unattainable solution 特別在[ 0 , 1 ]格上對無限論域方程a ? x = n (其中“ ? ”表示sup - inf合成)的解集的性質(zhì)作了討論,僅從方程的系數(shù)出發(fā)給出了方程解集非空的充要條件以及存在可達(dá)解或不可達(dá)解的充要條件。
T - s model is a novel fuzzy reasoning model which replaces the parameters of traditional reasoning system with linear partial equation . therefore , it can generate complicated nonlinear equation with fewer fuzzy rules . but the conclusional parameter is not a fuzzy rule but a linear equation , it can not be got from expert ' s experience and operational data directly . we must refine the parameter with some algorithm . by constructing t - s fuzzy neural networks we can solve the problem easily T - s模型是一種新穎的模糊推理模型,它以線性局域方程取代了一般推理過程中的常數(shù),因此可以用少量的模糊規(guī)則生成較復(fù)雜的非線性函數(shù)。但是由于結(jié)論參數(shù)是線性函數(shù)而非模糊數(shù),所以規(guī)則不能直接從專家經(jīng)驗和操作數(shù)據(jù)中直接得到,必須通過一定的算法進(jìn)行提煉。因此模型參數(shù)的辨識成為建立t - s型模糊系統(tǒng)的主要問題。
