Abstract
In this paper, we first consider fuzzy optimization problem (in short, (FOP)) and sequences of fuzzy optimization problems (in short, (FOP)n). Then we establish the concept of D-convergence of a sequence of fuzzy mappings and its characterizations. Finally, the Painlevé–Kuratowski lower convergence and the Painlevé–Kuratowski convergence of approximate solution sets for these problems are proposed using D-convergence of a sequence of fuzzy mappings. Some examples are provided to illustrate the essentialness of the imposed assumptions.
