Journal Article 2018 01 07 In this paper, we propose the new concept of optimal solution for fuzzy variational problems based on the possibility and necessity measures. Inspired by the well–known embedding theorem, we can transform the fuzzy variational problem into a bi–objective variational problem. Then the optimal solutions of fuzzy variational problem can be obtained by solving its corresponding biobjective variational problem. https://ansne.du.ac.ir/article_95_7730f3c58de6cb4c2ffa9bad90621be0.pdf
