The article considers the problem of competitiveness of domestic products in home and world markets, which is the main task of the state policy towards national revival. The creation of methods of optimization cost producer in the production of competitive products should be the main vector of the current economic policies of national production.A mathematical model with the numerical solution of the optimization problem is investigated. Manufacturer’s profit function is studied using a regression equation. The proposed methods allow to determine the economically optimal increase in product quality.

Keywords: level of product quality, mathematical models, manufacturer’s profit function.
