Abstract: This paper analyzed the component testability research situation, proposed a layered model based on fuzzy evaluation component testability assessment method. This method according to the fuzzy comprehensive evaluation principle, set up the index set and evaluation sets, and put forward the AHP, SCI}FCE and MCTFCE algorithm to make a more accurate evaluation results for the component testability. Simulation results showed that it was an effective evaluation method.

Key words: Component, Testability, Fuzzy comprehensive evaluation
