FORMATION DYNAMICS OF THE VOLUMES OF THE SUBSTANDARD MACHINES AND EQUIPMENT OF GENERAL ENGINEERING DESIGNATION IN UKRAINE

Abstract

Industrial scrap, substandard machines and equipment of general engineering designation as types of solid industrial waste can be widely used in the construction sphere for obtaining valuable materials: for the manufacturing of the construction materials with protective properties against electromagnetic radiation and static electricity, for the production of the anodic earthings, etc. That is why, determination of the regressional dependence, describing the dynamics of the volumes of the substandard machines and equipment of general engineering designation formation in Ukraine is an important scientific-engineering problem.

Aim of the research is determination of the regressional dependence, describing the dynamics of the volumes of the substandard machines and equipment of general engineering designation formation in Ukraine and can be used for the forecast of these volumes. In the process of studies method of the regressional analysis of the results of single factor experiments and other paired dependences with the selection of the rational type of function from sixteen most widely used variants by the criterion of maximum value of the correlation coefficient was used.

Regression was carried out on the base of linearised transformation, enabling to reduce non-linear dependence to linear one . Determination of the coefficients of regression equations was performed, applying the least-square method by means of the developed computer program "RegAnaliz”, the program is protected by the Certificate of the State Registration of the rights to the copyright object.

Adequate regression power dependence, describing the dynamics of the volumes of substandard machines and equipment of general engineering designation formation in Ukraine is obtained, it can be used for the forecast of such volumes. Graphic dependence, describing the dynamics of the formation of the volumes of the substandard machines and equipment is constructed, it enables to illustrate this dynamics and show the sufficient coincidence of the theoretical results with actual ones. It is established that in Ukraine in the period of 2017 – 2019 volumes of the substandard machines and equipment of general engineering designation formation decreased according to linear dependence.
