Yager ranking index in fuzzy bilevel optimization

Alina Ruzíyeva, S. Dempe


In the present paper a fuzzy bilevel optimization problem is under discussion. The purpose of the paper consists in finding an optimal solution for this problem. Besides the two well-known approaches (pessimistic and optimistic) there exists a quite new selection function approach, which we present here. A sensible attempt to solve a fuzzy bilevel optimization problem through reformulation to a crisp bilevel optimization problem is considered. Using Yager ranking indices technique an algorithm for searching an optimal solution of the fuzzy bilevel optimization problem is described.
