Method Research on Parameter Selection and Index Determination of Testability for Diesel Engine

Abstract

Considering the parameter selection and the index determination of testability are mainly based on expert experience, or in accordance with industrial routine, which cause application scope of selected parameters set to be small and randomness of selected parameters to be big, the proposed index may be too high or too low, the method of testability parameter selection and testability index determination of diesel engine are designed on the basis of the analytic hierarchy process and the eclectic approach, respectively. The minimum threshold value of testability parameter selection and testability index determination of diesel engine are determined, which provides the basis for the next testability modeling and analysis.
