  Article:   AN INTERVAL FUZZY MULTICRITERIA DECISION MAKING METHOD BASED ON THE EXPECTED VALUE.

Authors:  .
 
       
         
  Abstract:   In the present paper we extend fuzzy multi criteria decision making methods elaborated in some recent articles. We use intervals of trapezoidal fuzzy numbers instead of trapezoidal fuzzy numbers, which allows two choices or even a intermediate responses in a survey. The expected value is used for the ranking of intervals of trapezoidal fuzzy numbers. We elaborate an algorithm of rankings the alternatives versus criteria and weights of criteria given by intervals of trapezoidal fuzzy numbers. Theoretical considerations are illustrated by a practical example.
