- A vehicle ability to realise transport tasks may be restored by repairing only failed elements. This is called imperfect repair as the vehicle is not as good as new after such a repair. Preventive replacement is an example of imperfect repair as well. The advantage of such maintenance is that it enables controlling a reliability level of a fleet of vehicles. Sets of vehicles elements which should be replaced in that aim are derived on a base of statistical diagnosing with use of data about elements failures. The acceptable level of a failure risk while executing transportation tasks has been taken as a criterion. An algorithm for selecting elements for preventive replacement has been developed. It was shown that a level of a fleet reliability can be controlled by changing an order of a quantile function in coordination with a number of redundant objects. A computer simulation model of the vehicle fleet was used as an example to illustrate derived dependencies. In particular algorithm for selecting elements for preventive replacement, graph of model states, graphical interpretation of calculating new quantile orders, simulation experiments results for system n out of n, simulation experiments results for d = 2,5 are presented in the paper.
