Keywords: faultlessness, sprayer, probability, control, parameter, element, efficiency


The article discusses the application of numerical methods of second-order optimization in stochastic programming problems, which include the probability function of the impact on the failure rates of self-propelled sprayers systems built-in technical control, such as completeness and depth of technical control.
Analytical models of some typical failure-free structures of self-propelled sprayers have been developed, which take into ac-count the characteristics of technical control over the efficiency of the elements.
A graphical interpretation of the dependence of the reliability of self-propelled sprayers on the completeness of technical control is presented. The existence of the influence of completeness of technical control on the indicators of failure of structures is confirmed.
The considered approach with a similar analysis allows to reasonably make requirements to the characteristics of technical control systems of self-propelled sprayers.
