Modeling of Normativity of Criteria of Technical Level of Forage Harvesters Combines

The article presents the results of analytical calculations of methods for assessing the technical level of agricultural machinery products with their prospective standardization of forage harvesterscombines.From the author's point of view, it would be rational to assess the technical level as a function of the rate of change of indicators that determine the development of this type of equipment over a limited period of time, for example, over the life of the forage harvesterscombines. During this period, as a rule, you can consider the performance of two or three generations of this type of forage harvesters combines. Investigating the rate of change of parameters of a certain chronological series of analytical objects as an indicator of technical level, we can conclude that the difference in the rate of change of an indicator has the degree of influence of each indicator on the formation of initial properties that determine the ability of this technique at each stage of its development to meet the specific requirements of consumers. That is, only important indicators are subject to improvement or development. If the indicator is improving at an accelerated pace, it means that the importance of factors such as manufacturability or world conditions.
