Applying the mathematical apparatus, carried out approximation of experimental data characterizing the technological processes of the operations of the control parameters of the technical condition of the investigated combines a maintenance cycle, by types, certain parameters of the technical condition and work performed individual performers accepted modeling functions. The results of the evaluation of the errors of approximation show that for different processes, you can use various functions with the aim of obtaining the minimum error of estimation of technical condition of combine harvesters. The authors present the functions of the technological was built on the basis of the graphs tradeaplane works, a list of events and activities of their respective networks.
