【摘要】：多屬性群決策是在考慮多個屬性的前提下,由多個決策者對一組備選方案進(jìn)行選優(yōu)或排序的過程。當(dāng)前多屬性群決策主要關(guān)注在如何確切描述決策者的不確定思維及有效刻畫復(fù)雜決策環(huán)境方面,其體現(xiàn)為選用多種形式的決策信息,選擇合適的聚合算子,多屬性決策模型的選用等。本文分別在決策信息為三角直覺模糊數(shù)和2-維區(qū)間中智語言數(shù)的背景下,以PROMETHEEⅡ方法和Choquet積分聚合算子來構(gòu)建新的群決策模型。具體包含以下內(nèi)容:首先,在三角直覺模糊數(shù)形式下,以Choquet積分聚合算子來反映屬性間相互依賴的現(xiàn)象,并形成個體決策者的綜合評價信息,進(jìn)而應(yīng)用PROMETHEE Ⅱ方法得到群體的綜合評價信息及方案排序。此外,本文研究了基于三角直覺模糊數(shù)的Choquet積分聚合算子的相關(guān)性質(zhì)。其次,為體現(xiàn)決策環(huán)境的復(fù)雜性和專家評價過程中的不確定和不一致性,本文結(jié)合區(qū)間中智數(shù)和2-維語言變量定義2-維區(qū)間中智語言數(shù),即對于決策者給出的語言評價結(jié)果增加了可以表示其可靠性的主觀評價維度,從而提高了對目標(biāo)評價的準(zhǔn)確性。此外,本文定義了 2-維區(qū)間中智語言數(shù)的運(yùn)算法則和比較規(guī)則,在此基礎(chǔ)上結(jié)合Choquet積分聚合算子和PROMETHEE Ⅱ構(gòu)建了群決策模型,并將其應(yīng)用于畢業(yè)論文評價的數(shù)值例子中。
[Abstract]:Multi-attribute group decision making is a process of selecting or ranking a group of alternatives by multiple decision makers on the premise of considering multiple attributes. At present, multi-attribute group decision making focuses on how to accurately describe the uncertain thinking of decision makers and how to effectively depict the complex decision-making environment, which is reflected in the selection of various forms of decision information and the selection of appropriate aggregation operators. Selection of multiple attribute decision models. In this paper, under the background that the decision information is triangular intuitionistic fuzzy number and intelligent language number in 2-dimensional interval, a new group decision model is constructed by using PROMETHEE 鈪，
