Keywords: optimization, panel structure

The optimum design problem is one of the inverse tasks, that means the structure parameters are calculated according to a known criteria of the selection, mathematically described as a cost function. The factor determining the development of optimum design besides the hardware equipment is the developing of the new methods and new mathematical programming algorithms. The optimum design of a skin stringer panel using the method of non-linear programming of Himelblaua [2] is presented in this paper. The cost function is the mass of the panel. The constrains has to be chosen so that our panel should satisfied the requirements for local and global panel buckling, local and global stringer buckling and it should satisfy as well as the static resistance demands.
