Modeling the weightof criteria for determining the technical level of agricultural machines

The article presents the results of theoretical research on the methodological provisions of the weight of the criteria in determining the technical level of agricultural machinery. The expediency of using relative, in parts of change, values of evaluation indicators, which allows to objectively and reliably obtain the value of the weight of the criteria in determining the technical level of agricultural machinery. The applied problem of determining the weights of the criteria in the study of the technical level of combine harvesters is considered. Five criteria are substantiated: reduction of direct costs, reduction of energy consumption, reduction of labour costs, reduction of material consumption, increase of reliability. The weight of the criterion reflects the degree of its importance in the rank of the sequence, their values are in the range 0…1. Five indicators are substantiated: operating costs, direct fuel costs, specific labour costs, specific material consumption, failure time. It is established that in the process of operation of the combine harvester Slavutich KZC-9M with a reduction of 30% of operating costs, the weight in determining the technical level is 0.1473. Studies have shown that a 25% reduction in direct fuel consumption is 0.1228 weight in determining the technical level of the combine harvesters.
