This paper deals with optimization of non-linear dynamic consumption model withnconsumer classes which was introduced by Kulikowski. In the model the utility function of each consumer classes is assumed to be approximated by the generalized Cobb-Douglas function and the problem of multicriteria optimization is formulated. Introducing an objective function which is expressed as a function ofnutility function, we first optimize the model with respect to another criterion which is a linear combination ofnutility functionals, The solution of the linear combination problem is obtained as a function of the weighting factors in the linear combination functional. A search procedure is then used to determine the optimum values of these weighting factors for the specified objective function.
