【摘要】：在現(xiàn)實生活中,存在著大量語言值多屬性群決策問題,它具有廣泛的實際應(yīng)用背景。然而,在決策過程中由于外部環(huán)境的復(fù)雜性和難預(yù)測性、決策問題本身的模糊性、人類認(rèn)識的局限性,以致決策者不能用簡單語言值來表達(dá)自己的評價意見,而是以不確定語言或直覺語言的形式給出。不確定語言體現(xiàn)了人類的思維方式,直覺語言體現(xiàn)了決策者對評價值的信心度和猶豫程度。本文對這兩類語言值多屬性群決策問題進行了探究,提出了對應(yīng)的決策模型和方法并通過實例分析說明了它們的有效性和實用性。本文研究的主要內(nèi)容如下:1.提出基于可能度的PROMETHEE Ⅱ不確定語言多屬性決策模型。該模型在可能度概念的基礎(chǔ)上定義了全局優(yōu)勢可能度,將其引入到PROMETHEEⅡ中優(yōu)先函數(shù)的構(gòu)造,在此基礎(chǔ)上定義全局凈流,并根據(jù)全局凈流得到方案的排序。最后通過實例分析說明提出模型的有效性。2.將可能度的概念引入到ELECTRE Ⅱ中屬性集的劃分上,在考慮同一屬性下的差異的基礎(chǔ)上,重新定義了和諧性指標(biāo)�；诖�,建立基于可能度的ELECTREⅡ不確定語言多屬性決策模型,并將該模型運用于社會經(jīng)濟系統(tǒng)評價研究。3.將補償加權(quán)平均聚合算子拓展到直覺語言環(huán)境,并考慮聚合過程序的關(guān)系和聚合過程中聚合數(shù)據(jù)間的支持度,分別定義了兩種直覺語言補償性聚合算子。在此基礎(chǔ)上,構(gòu)建了兩種解決直覺語言多屬性群決策問題的方法。最后運用算例驗證其有效性。
[Abstract]:In real life, there are a large number of linguistic valued multi-attribute group decision making problems, which have a wide range of practical application background. However, in the decision-making process, due to the complexity and unpredictability of the external environment, the decision-making problem itself is fuzzy. Human cognition is so limited that decision makers can't express their opinions in simple language, but in the form of uncertain language or intuitive language. Uncertain language reflects the way of human thinking. Intuitionistic language reflects the degree of confidence and hesitation of decision makers in evaluating value. The corresponding decision models and methods are proposed, and their effectiveness and practicability are illustrated by an example. The main contents of this paper are as follows: 1. A PROMETHEE 鈪，
