Applications of the Fuzzy Weighted Average of Fuzzy Numbers in Decision Making Models
نویسندگان
چکیده
The paper deals with the operation of fuzzy weighted average of fuzzy numbers. The operation can be applied to the aggregation of partial fuzzy evaluations in fuzzy models of multiple criteria decision making and to the computation of expected fuzzy evaluations of alternatives in discrete fuzzy-stochastic models of decision making under risk. Normalized fuzzy weights figuring in the operation have to form a special structure of fuzzy numbers; its properties will be studied and the practical procedures for setting them will be proposed. A fuzzy weighted average of fuzzy numbers with normalized fuzzy weights will be defined, an effective algorithm of its calculation will be described, and its uncertainty will be studied.

In some multi-attribute decision making (MADM) problems, various relationships among the decision attributes should be considered. This paper investigates the prioritization relationship of attributes in MADM with trapezoidal intuitionistic fuzzy numbers (TrIFNs). TrIFNs are a special intuitionistic fuzzy set on a real number set and have the better capability to model ill-known quantities. Fir...

متن کاملA new approach to rank the decision making units in presence of infeasibility in intuitionistic fuzzy environment
Data envelopment analysis (DEA) is a linear programming based methodology to determine the relative performance efficiencies of homogeneous decision making units (DMUs). In real world applications, some input and output datas do not possess crisp/fuzzy essence but they possess intuitionistic fuzzy (IF) essence. So, in this study, we develop an IF BCC (IFBCC) and an IF super efficiency BCC (IFSE...
