Research on Model-Driven Analysis Method of Testability Verification Requirement

Abstract

Guided by quantitative indicators, traditional testability verification mode cannot fully verify the compliance of equipment test and diagnosis capability, which leads to the disconnection between testability verification and ordinal design. In order to solve this problem, it is imperative to implement requirement oriented testability verification. However, under the MBSE development mode, there is still a lack of reasonable and effective analysis method of testability verification requirement. Therefore, a model-driven analysis method of testability verification requirement is constructed in this paper, by introducing operational scenario modeling and analysis, identification and control of key function fault, and requirement decomposition based on analysis of MOE. Meanwhile, this paper puts forward the implementation path of this method with the support of modeling and analysis tools such as MagicDraw, which lays the foundation for promoting capability-oriented and requirement-oriented verification for testability of equipment.
