On the issue of increasing the practical value of economic-mathematical models

It is proved that under strong competition at consumer market and, most of all, in the condition of dynamic broadening and improving of goods assortment, it is impossible to form optimal assortment plans with orientation on the profit increase only; it is also necessary to ensure minimization of distribution costs. It is demonstrated that the duality theory allows solving both tasks. The author proposes the algorithm of forming an optimal assortment plan of a trading company based on solving the direct and dual task of linear programming. The economical interpretation of possible reasons why the task will not have any solution is given.
