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

Fuzzy optimization
A new model for solving fuzzy linear fractional programming problem with ranking function

Sapan Kumar Das; Tarni Mandal

Volume 4, Issue 2 , October 2017, , Pages 89-96


  In this paper, we studied fuzzy linear fractional programming (FLFP) problems with trapezoidal fuzzy numbers where the objective functions are fuzzy numbers and the constraints are real numbers. In this study, in order to obtain the fuzzy optimal solution with unrestricted variables and parameters, a ...  Read More

Shortest Path Problem in Network with Type-2 Triangular Fuzzy Arc Length

Ranjan Kumar; Sripati Jha; Ramayan Singh

Volume 4, Issue 1 , September 2017, , Pages 1-7


  In traditional shortest path problem it is always determined that the parameters (Time, Cost and Distance etc.) are fixed between different nodes. But in real life situations where uncertain parameters exist, parameters are considered as fuzzy numbers. In this paper, we  explained the application ...  Read More
