1、南京航空航天大學(xué)碩士學(xué)位論文摘要灰色關(guān)聯(lián)分析不僅是灰色系統(tǒng)理論的重要組成部分也是灰色系統(tǒng)分析預(yù)測(cè)和決策的基石隨著灰色系統(tǒng)理論在各個(gè)方面的推廣應(yīng)用對(duì)灰色關(guān)聯(lián)分析的關(guān)注也越來越多本文對(duì)灰色關(guān)聯(lián)分析相關(guān)理論及其應(yīng)用進(jìn)行了研究和總結(jié)就灰色關(guān)聯(lián)分析模型存在的一些不足進(jìn)行了探討針對(duì)灰色T型關(guān)聯(lián)度模型和灰色斜率關(guān)聯(lián)度模型進(jìn)行了研究和改進(jìn)以期更好地將灰色關(guān)聯(lián)度模型應(yīng)用于實(shí)際問題的分析中本文的研究工作主要有以下幾個(gè)方面首先系統(tǒng)地總結(jié)了國(guó)內(nèi)外對(duì)灰色關(guān)聯(lián)分析的理論與應(yīng)用研究成果以及本文的主要研究?jī)?nèi)容其次對(duì)灰色關(guān)聯(lián)度模型
