But in fact their quantity values of the parameter indexes are often difficultly confirmed and they have fuzzy characteristics by theirself 但實(shí)際上這些參數(shù)指標(biāo)的量值往往難以精確確定,本身具有模糊性的特點(diǎn)。
Since 1980s , the application research of some fuzzy mathematic methods on the earthquake prediction have been developed in accordance to the fuzzy characteristic of the information during preparing earthquake 摘要20世紀(jì)80年代以來(lái),針對(duì)地震孕育期間孕震信息的模糊性,國(guó)內(nèi)開(kāi)展了多項(xiàng)模糊數(shù)學(xué)方法在地震預(yù)測(cè)中的應(yīng)用研究。
According to the fuzzy characteristic of nonfinancial performance appraisal index , i use fuzzy general appraisal method to appraise the nonfinancial index under the weight - determined by ahp . i get impersonal conclution of the appraisal for nonfinancial index 然后根據(jù)非財(cái)務(wù)指標(biāo)具有模糊性的特點(diǎn),采用模糊綜合評(píng)價(jià)的方法運(yùn)用ahp法確定的權(quán)重對(duì)非財(cái)務(wù)指標(biāo)進(jìn)行綜合評(píng)價(jià),取得了比較客觀的評(píng)價(jià)結(jié)論。
( 3 ) taking into account the fuzzy characteristics existed in selecting of the representative year , the fuzzy clustering method is adopted to the cluster analysis of year runoff data , and the cluster center vectors standing for the type of year , that is , abundant , moderate and deficient , are obtained ( 3 )考慮到典型年判定時(shí)存在的模糊性,將模糊聚類(lèi)法用于年徑流分析,由此求得分別代表豐、平、枯各種年型的聚類(lèi)中心向量。
The main achievements of this thesis are as follows : ( 1 ) studies the existed literatures home and abroad widely on risk assessment , the intension and extension about the five categories of uncertainty ( randomicity , fuzzy characteristic , gray characteristic , unascertained characteristic , universal gray characteristic ) 取得的主要成果有: ( 1 )較系統(tǒng)地研究了國(guó)內(nèi)外有關(guān)風(fēng)險(xiǎn)評(píng)估的理論、方法、技術(shù)成果和五種不確定性(隨機(jī)性、模糊性、灰性、未確知性、泛灰性)的內(nèi)涵、外延。
