In this paper we focus on a kind of quadratic programming with fuzzy numbers and variables. First by using a fuzzy ranking and arithmetic operation, we transform these problems to crisp model with nonlinear objective and linear constraints and then we solve this problem by alternative method and obtain an optimal solution. The technique is useful to apply on numerical problems, reduces the labor work and save valuable time.
