New Fuzzy Logic Research from Concordia University Outlined

摘要

2011 OCT 24 - (VerticalNews.com) -- According to the authors of recent researchrnpublished in the journal Expert Systems with Applications, "This paper investigates the dynamicrnintuitionistic fuzzy multi-attribute group decision making (DIF-MAGDM) problems, in whichrnall the attribute values provided by multiple decision makers (DMs) at different periods take thernform of intuitionistic fuzzy numbers (IFNs), and develops an interactive method to solve thernDIF-MAGDM problems. The developed method first aggregates the individual intuitionisticrnfuzzy decision matrices at different periods into an individual collective intuitionistic fuzzyrndecision matrix for each decision maker by using the dynamic intuitionistic fuzzy weightedrnaveraging (DIFWA) operator, and then employs intuitionistic fuzzy TOPSIS method to calculaternthe individual relative closeness coefficient of each alternative for each decision maker andrnobtain the individual ranking of alternatives."
