To the formalization of the processes of aging and restoration of cars

In terms as close as possible to mathematical theory of reliability, the nature of the loss and restoration of cars is described, considered as probabilistic system aging elements with incomplete recovery. Analytical researches showed that the flow of demands for the system of maintenance and repair (SMR) of the cars presented thus is described by the composition of laws of distribution which decision leads to analytically unsoluble multidimensional integrals. Consequently, traditional economic and mathematical models in which the analogue of the object of research used analytical expressions can't be used in the solution of tasks on further improvement of the system resistance machines aging on correct scientific grounds. It is shown that in the course of maintenance of cars continuous redistribu- tion of resources of their components happens opera- tions of repair and replacement, as a result each indi-vidual car is characterized by uncertainty of technical condition in time...
