Methodological aspects of comparison of parameters of various technologies for post-harvest cleaning of grain

The article discusses aspects of comparison of various technologies for post-harvest grain cleaning. The relevance of comparing the parameters of various grain cleaning technologies is substantiated, which consists in the possibility of determining the most economically feasible technology for use in the conditions of a particular farm or region as a whole, as well as identifying the most energy-efficient technology and technical means with the best indicators of reliability and durability. Existing methodological and logical approaches for comparing different technologies are described, the steps necessary to build a comparative model of optimal technology parameters are identified, as well as tools for creating mathematical models, performing calculations and optimizing solutions. A number of scientific and consulting organizations with the competence to compare various technologies for post-harvest grain cleaning and optimize their parameters are presented.
