Model-based Systems Engineering for Prognostic and Health Management Design

The methods of traditional system design are passed in document form, and it is difficult to trace back if the document changes or errors are found in the downstream design. Moreover, there is no systematic development guidance and design, which makes the designed model complex and simple, and makes model-driven simulation impossible, resulting in development progress slowly. In this paper, the PHM functional architecture of aircraft avionics system is studied by using the system engineering design concept based on model. Using HarmonySE method of system design and Rhapsody of tool model driver, the functional architecture of PHM system was designed.
