Discussion on testability distribution method for series-parallel connection

摘要

Aimed at the diversification of the distribution methods, the relationship is studied between system testability index and the system element testability indexes, and the factors are analyzed, which have influence on determining testability indexes. It introduces three methods including fault rate method, weighting method and analytic of hierarchy process (AHP) for series-parallel connection and gives an example to analyze these methods proving the practicability of fault rate method and AHP.
