The activity of the enterprise is inseparable from the adoption of managerial decisions. Forecasting is one of the tools that helps management to assess the future performance. Financial forecasting plays a key role in the development of a company's strategy and is an integral part of financial management. This article discusses the tasks and methods of financial forecasting, as well as the factors on the basis of which the choice of forecasting methodology is made for a successful assessment of the financial position of an enterprise and making the right management decisions.

Volleyball serves can be divided into power, planning and mounted. Power serve achievements are characterized by high initial velocity, gliding type serves are characterized by irregular ball movement, and the goal of promotion is to land the ball on the side of the nearest opponent, possibly in the net. There is no theoretical analysis of these innings in the literature. The article examines the power and mounted feed.

In given article the technique of planning of carrying out of research and development on the basis of the volume determined models is described. Basically, the problems concerning top level of hierarchy, namely, problems of definition of the schedule chart of realization of the basic stages of research and development and volumes of expenses necessary for it are considered. The most effective and modern approach to realization of such substantiation is use of mathematical models. It is thus essential that the models applied to the decision of problems of this level, should consider not only internal properties of the enterprise are models of its organizational system, but also consider with accessible completeness of property of environment of the enterprise. As this completeness is rather limited, in view of incompleteness of the information on properties of environment of the enterprise, the planning technique should provide possibility of correction of planned offers, their recalculation under the specified data.

It shows the need for the development of mathematical models to predict the feasibility of indicators and substantiation of optimal combination of technical solutions for the disintegration of rocks in order to minimize the energy consumption for the realization of a given process.

Вased on the experience of Petrozavodsk University, it is shown that the competitiveness of universities in the IT-goods and IT-services market in the timber industry complex can be ensured by mathematical modeling and solving optimization problems.

This monographic research describes the mathematical models for heat treatment of rubber products by steam heating in the autoclave. Also the calculation methods of energy losses by steam heating in the autoclave are described. The technique of calculating the energy loss during heating with steam in an autoclave is explored.

According to the authors, the major factor influencing the product yield in obtaining the mathematical model of the recycling process optimization of the mixture of bentonite clay and silted slurry of alumina production is x1 and x 2. The obtained models provide the opportunity to use the data in studying the recycling process of the mixture of bentonite clay and silted slurry.

Mathematical simulation to determine the optimal shift points to initiate movement at the maximum permissible speed in low gear and get the highest possible intensity of acceleration and minimize the time in the area of movement.

In this paper the application of mathematical modeling for optimization of production, based on the modification model of the transport task is considered. The solution of an objective by means of information technologies is provided.

The single-axis angular rate table is intended for navigation system testing. The table is considered as mechanical system with elastic deformations of shafts and coupling. The natural frequencies calculation is based on the represented mathematical model. The numerical results show that the values of natural frequencies are large and therefore designed system is far from resonance.

This article analyzes the modern numerical methods for solving linear algebraic equation system. They focus on the study of the field of applicability of the methods considered. Modern numerical methods often come down and solve linear algebraic equation system, so the question remains relevant today.
