Abstract :
A multiobjective security game problem with fuzzy payos is studied in this paper. The problem is formulated as a
bilevel programming problem with fuzzy coecients. Using the idea of nearest interval approximation of fuzzy numbers,
the problem is transformed into a bilevel programming problem with interval coecients. The Karush-Kuhn-Tucker
conditions is applied then to reduce the problem to an interval multiobjective single-level problem. It is shown that the
solutions of this problem are obtained by solving a single-objective programming problem. Validity and applicability
of the method are illustrated by a practical example.
