[Integrated evaluation on system reliability of a space metabolism simulation device].
OBJECTIVE
To define the lower confidence limit of the system reliability of the space metabolism simulation device by using the test data of the comprising units in their development phases.


METHODS
A new method for defining the environmental conversion factors of failure times has been given basing on the AMSAA model, and the MTBF point evaluated values and lower confidence limits of the units were defined, at last, the lower confidence limit of the system reliability was obtained using L-M method.


RESULTS
The lower confidence limit of the system reliability under confidence level of 0.8 is 0.9281, which is consistent with the result obtained by the classic system reliability evaluation method.


CONCLUSIONS
Integrated system reliability evaluation using the proposed method can well satisfy the need in engineering.
