Research on a Determination Method for System Testability Index of Complicated Equipment

Due to the lack of scientific determination methods for testability index of the equipment in the concept phase of development,a similar eclectic quotiety method based on multiple attribute decision making is proposed to resolve this problem.Considering the user's testability requirement and the testability level that the contractor can achieve,the method analyzes various factors which influence the system testability,applies the theory of multiple decision making to work out the testability level that the contractor can achieve,and uses the similar eclectic quotiety to determine the testability index.Finally,the availability of the proposed method is verified by the instantiation.
