Abstract

The stages of the life cycle of complex technical products, such as tractors and self-propelled agricultural machinery, are considered. The need for adjusting /extending/ the repair interval of individual units and assemblies is justified.
A methodology for the technical and economic assessment of the repair interval of tractor units and self-propelled agricultural machinery has been developed, which takes into account the economic effect of extending the repair period, the relative share of the costs of purchasing replacement units and the set value of the confidence probability of the resource of the units.
