Improving the performance of tractors in agriculture

The indicator of the workability of imported tractors is determined by the expression of having the kind of extreme challenges, in which components models are represented by linear equations. To solve such problems the known simplex method is used in research practice in different production systems that allows deciding linear optimization problems with an acceptable error from the mathematical point of view. The experimental data for determining the indicator of the tractors' workability are gathered in the real conditions of foreign agricultural machinery usage on the farms of the Irkutsk region. As a result of the experimental collection of fundamental data groups of general and specific factors of the potential work-ability of imported tractors are identified. Thus, as a result, solutions of an extreme experimental task of the maximum value finding of an indicator of operability of tractors, allows allocating factors which intensity of use is reached by a variation of coefficients of real technical condition, technical use and losses of productivity of tractors.
