METHODOLOGY OF THE ANALYTICAL MODELING AND FACTOR ANALYSIS OF THE PRODUCTION EQUIPMENT PRODUCTIVITY
The article deals with the methodology of modeling and factor analysis of a production equipment unit productivity. It is emphasized that the productivity is an important generalizing indicator, that reflects the efficiency of the production equipment use. The final results of any enterprise’s activity directly depend on its absolute value and growth rates. The change of this indicator is influenced by various factors, that characterize the availability, structure and use of the production equipment in terms of time and capacity. In this regard, the factor analysis of the given indicator, i.e. the study of the influence of any individual factors on its change, has a relevant importance. The article emphasizes that the mathematical modeling of this indicator is an important way of solving any economic and statistical tasks, in particular, of studying the influence of the most important factors on the change in the productivity of a production equipment unit. The calculation of the quantitative influence of the mentioned factors on the change in the productivity of a production equipment unit is proposed to be carried out on the basis of the chain substitutions method. In the process of modeling of the factor systems of this indicator it is proposed to implement a phased factor analysis of a production equipment unit productivity, i.e. to consistently decompose the value of this index into a number of its initial indicators, which depending on the goals and objectives of the enterprise, gives the possibility to calculate the influence of those factors, that are the most significant and relevant at the moment. The methodology of the analytical modeling and factor analysis of production equipment productivity, given in the article, allows to present this indicator in the form of some deterministic multiplicative models, to determine the influence of the most important factors on its change, to investigate the regularities of such an influence, to justify the appropriate management decisions regarding the further development of the enterprise.
