However, in the process of evaluating, because of the limitation of human knowledge and the complexity of problems, an efficient GMCDM approach under uncertain environment still need to be further explored. Thus, in this paper, a novel GMCDM approach with linguistic Z-numbers based on TOPSIS and Choquet integral is proposed. Firstly, since linguistic Z-numbers performs better in coping with uncertain information, it is used to express the evaluation information. Secondly, TOPSIS, one of the most useful and systematic multi-criteria decision-making (MCDM) method, is adopted as the framework of the proposed approach. Thirdly, frequently it exists interaction between criteria, so Choquet integral is introduced to capture this kind of influence. What\u2019s more, viewing that decision makers (DMs) show different preferences for uncertainty, the risk preference is regarded as a vital parameter when calculating the score of linguistic Z-numbers. An application in supplier selection is illustrated to demonstrate the effectiveness of the proposed approach. Finally, a further comparison and discussion of the proposed GMCDM method is given.<\/jats:p>","DOI":"10.3233\/jifs-200318","type":"journal-article","created":{"date-parts":[[2020,6,19]],"date-time":"2020-06-19T12:08:48Z","timestamp":1592568528000},"page":"4285-4298","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["A GMCDM approach with linguistic Z-numbers based on TOPSIS and Choquet integral considering risk preference"],"prefix":"10.1177","volume":"39","author":[{"given":"Ran","family":"Tao","sequence":"first","affiliation":[{"name":"School of Computer and Information Science, Southwest University, Chongqing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fuyuan","family":"Xiao","sequence":"additional","affiliation":[{"name":"School of Computer and Information Science, Southwest University, Chongqing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,6,16]]},"reference":[{"key":"e_1_3_2_2_2","article-title":"Multiple attribute decision making: an introduction","volume":"104","author":"Yoon K.P.","year":"1995","unstructured":"YoonK.P. and HwangC., Multiple attribute decision making: an introduction, Sage Publications 104 (1995).","journal-title":"Sage Publications"},{"key":"e_1_3_2_3_2","unstructured":"ChuT. and LeH.T.
