A vague-set-based fuzzy multi-objective decision making model for bidding purchase
Abstract：A vague-set-based fuzzy multi-objective decision making model is developed for evaluating bidding plans in a bidding purchase process. A group of decision-makers (DMs) first independently assess bidding plans according to their experience and preferences, and these assessments may be expressed as linguistic terms, which are then converted to fuzzy numbers. The resulting decision matrices are then transformed to objective membership grade matrices. The lower bound of satisfaction and upper bound of dissatisfaction are used to determine each bidding plans supporting, opposing, and neutral objective sets, which together determine the vague value of a bidding plan. Finally, a score function is employed to rank all bidding plans. A new score function based on vague sets is introduced in the model and a novel method is presented for calculating the lower bound of satisfaction and upper bound of dissatisfaction. In a vague-set-based fuzzy multi-objective decision making model, different valuations for upper and lower bounds of satisfaction usually lead to distinct ranking results. Therefore, it is crucial to effectively contain DMs arbitrariness and subjectivity when these values are determined. 作者： Author： WANG Zhou-jing[1] QIAN Edward Y.[2] 作者单位： Department of Automation, Xiamen University, Xiamen 361005, ChinaCenter for Research of Private Economy, Zhejiang University, Hangzhou 310027, China 期 刊： 浙江大学学报A（英文版） ISTICEISCI Journal： JOURNAL OF ZHEJIANG UNIVERSITY SCIENCE A 年，卷(期)： 2007, 8(4) 分类号： N949 Keywords： Fuzzy multi-objective decision making model Vague set Score function Lower bound of satisfaction Upper bound of dissatisfaction 机标分类号： O1 TP3 机标关键词： decision making score function upper bound upper and lower bounds membership grade linguistic terms fuzzy numbers vague sets 基金项目： Department of Automation,Xiamen University, China A vague-set-based fuzzy multi-objective decision making model for bidding purchase[期刊论文] 浙江大学学报A（英文版） --2007, 8(4)A vague-set-based fuzzy multi-objective decision making model is developed for evaluating bidding plans in a bidding purchase process.
