  Article:   APPROXIMATION OF FUZZY NUMBERS BY TRAPEZOIDAL FUZZY NUMBERS PRESERVING THE CORE AND THE EXPECTED VALUE.

Authors:  .
 
       
         
  Abstract:  

In this paper, we have suggested a new trapezoidal approximation of a fuzzy number, preserving the core and the expected value of fuzzy numbers. We have proved that the trapezoidal approximation of fuzzy numbers preserving the core and the expected value is always a fuzzy number. We have discussed the properties of this approximation.

Mathematics Subject Classification (2010): 03E72, 47S40.

Keywords: Fuzzy numbers, trapezoidal fuzzy numbers, trapezoidal approximation.
