Fuzzy optimization
A new approach to solve fully fuzzy linear programming problem

Faranak Mahmoudi; Seyed Hadi Nasseri

Volume 6, Issue 2 , June 2019, , Pages 139-149


  Today, human decisions are more than ever based on information. But most of this information is not definitive, and in this situation, logical decision making is very difficult based on this uncertainty. Different methods are used to represent this uncertainty, including the fuzzy numbers. The fuzzy ...  Read More

A Generalized Model for Fuzzy Linear Programs with Trapezoidal Fuzzy Numbers

Seyed Hadi Nasseri; Hadi Zavieh; Seyedeh Maedeh Mirmohseni

Volume 4, Issue 1 , September 2017, , Pages 24-38


  ‎ In this paper, we generalize a linear programming problem with symmetric trapezoidal ‎fuzzy number which is introduced by Ganesan and et al. in [3] to a general kind of trapezoidal fuzzy number. In this way, we first establish a new ‏arithmetic operation for multiplication of two ‏trapezoidal ...  Read More
