Models and methods for evaluating the optimal size of the enterprise's production segment

The article presents a theoretical approach, mathematical models and numerical algorithms for assessing the optimal size of the production segment of an industrial corporation operating in the conditions of changing material and commodity markets. The authors adhere to the neoclassical concept of production efficiency in an open (in the sense of competitive) commodity, material and financial markets. However, while in neoclassical microeconomics the marginal revenue per unit of gross costs of the main production activity is an estimate of the optimality of the size of the enterprise, then in the approach proposed by the author, the gross income is considered as a criterion for the optimality of the corporation’s production segment, taking into account the results of not only the main, but also non-operating activities, which, usually ignored in neoclassical theory. The models of the optimal size of the corporation’s production segment presented in the article are more realistic than their «classic» counterparts, since the restrictions take into account not only production, technological, financial and resource indicators, but also market and risk indicators, which increases the objectivity and accuracy of estimates...
