Research on a comprehensive evaluation of equipment maintainability qualitative index based on virtual prototypes

Abstract

As new equipment development cycles are too long, there is an urgent need for comprehensive evaluation in the virtual prototype stage for equipment maintainability. This paper takes the characteristics of the design stage to construct a comprehensive evaluation index system, and puts forward subjective and objective weighting methods in a combination weighting method for an index of weights. Finally, a practical example is given to verify the method's rationality. The results of this study of comprehensive evaluation of new equipment maintainability and subsequent stereotypes have important reference value.
