Abstract: System often faults due to parts failure during operation. After replacement, values of system reliability indexes change, which is caused by the change of age distribution of system parts. And system reliability analysis method is studied. System is regarded as a set of all the same parts in a range, and it is assumed that system was composed of repairable parts which are all the same. Mathematical model of system parts is built, and results of system reliability descending with running time, system replacement ratio ascending are gotten. These results, which are important to the spare parts purchasing, cascade utilization of parts and maintenance policy making, are illustrated by actual data from the airline company.

Key words: reliability, system reliability, system replacement ratio, unlimited repairable parts
