| Abstract: | According to the AMSAA model and based on genetic algorithm the time environmental conversion factors of the units were determined using test data of the comprising units of one aviation fire control system in its development phase, and the evaluated MTBF point values and lower confidence limits of the units were determined, at last the lower confidence limit of the system reliability was given using L-M method. The research result indicated that the system reliability assessment by this way is near the reliability level based on real data which was produced after its finalization, system reliability assessment by this way can well satisfy the need in engineering. |
