Modeling of Dynamics of the Company’s Share in the Solid Fuel Market

The task of identification of the interval discrete dynamic model of the company's share in the solid fuel market is considered in the paper. For building such models, it is proposed to use the methods of structural and parametric identification, which are based on the analysis of the interval data. The built mathematical model is a methodological basis for forecasting the enterprise commodity products market shares for the years to come. The advantage of such a model is its ability to be quickly adjusted to other conditions by specifying performance for the first three months of the year.
