考慮可信度的猶豫模糊多屬性決策方法研究

摘要： 為深入研究猶豫環(huán)境下多屬性決策問題,提高決策的科學(xué)性和準(zhǔn)確性,本文在已有研究成果的基礎(chǔ)上,充分考慮猶豫模糊集中隸屬度函數(shù)的差異性對(duì)決策結(jié)果的影響。論文引入了專家可信度的思想對(duì)猶豫模糊信息進(jìn)行集成,將一組數(shù)值轉(zhuǎn)化為一個(gè)數(shù)值,進(jìn)而實(shí)現(xiàn)猶豫模糊信息的對(duì)比研究,以此構(gòu)建了一種考慮可信度的猶豫模糊多屬性決策方法。最后,論文以汽車零部件供應(yīng)商選擇問題為例,驗(yàn)證了該方法的有效性。
In order to further study the multi-attribute decision making problem in the hesitant fuzzy environment and improve the scientificity and accuracy of decision-making,this paper fully considers the influence of the difference of membership function on the decision results based on the existing research results. Using the idea of expert credibility,the comparative study of the hesitating fuzzy information is realized by converting a set of values into a single value,and a hesitant fuzzy multi-attribute decision making method considering reliability is proposed. Finally,this paper takes the selection of auto parts suppliers as an example to demonstrate the availability of this method.
