Planning Expenditures of Industrial Enterprises With the use of Methods of Economic and Mathematical Modelling

The issue of search for directions of optimisation of activity of industrial enterprises of Ukraine is one of the priority tasks of their strategic development under the current crisis economic conditions. The current situation is such that the top-management of industrial enterprises practically does not pay sufficient attention to reduction of the level of expenditures of industrial enterprises, that is why the article offers to use methods of economic and mathematical modelling when planning expenditures of industrial enterprises. One of such methods is linear approximation, which gives an opportunity to use factual data about activity of enterprises, namely dynamics of expenditures of the main type of activity and dynamics of volumes of sold products, in order to build a model of dependence "expenditures of the main type of activity - volume of sales". The built models allow determination of enterprises, at which influence of expenditures of the main activity upon the volume of sold products is positive, i.e. volume of products increases with the increase of expenditures of the main activity, and enterprises, which have either negative relation between the volume of sold products and expenditures of the main activity or positive, but the determination ratio tends to zero. The conducted analysis of the built models once more confirms a set of problems of engineering enterprises, upon solution of which further development of these enterprises and efficiency of their activity depend. A special place in this process takes planning, since it provides an opportunity to use the analysed factual data about activity of industrial enterprises in order to plan expenditures of the main type of activity and further development of enterprises.
