Namely, the weighting method is used to find its weakly $LU$-efficient solution and $LU$-efficient solution. Therefore, the weighted variational problem is introduced for the given nonlinear multiobjective interval-valued variational problem. Then, under appropriate convexity assumptions, the equivalance between a (weakly) $LU$-efficient solution of the original nonlinear multiobjective interval-valued variational problem and an optimal solution of its associated weighting variational problem is established. https://comb-opt.azaruniv.ac.ir/article_14864_70d9205d8ee96caaa372240cfa35c028.pdf
