Prediction of the effective development of the enterprise implies the need for mathematical modelling of the leading financial and economic indicators of its life. High variability of approaches to the assessment and selection of indicators determines the existence of various approaches to their modelling.The complexity and complexity of the structure of economic activity of the enterprise, suggests the possibility of splitting the general situation into more specific cases, which allows you to apply a logical procedure to them, which is a simulation.The use of mathematical modelling allows you to speed up the economic analysis, contribute to a complete account of the influence of factors on the results of operations, increase the accuracy of calculations. It allows you to get a clear idea of the investigated object, to identify relationships, analyze features and give an accurate forecast of the development and changes in the basic financial and economic parameters of the enterprise.
