The Information Flow Model

  • William R. Simpson
  • John W. Sheppard


To address the problems of performing system diagnosis and analyzing system testability, we introduce the concept of an information flow model. This model-based approach to system test and diagnosis incorporates techniques from information fusion and artificial intelligence to guide analysis. The model represents the problem to be solved as information flow. Tests provide information and diagnostic inference combines information from multiple tests using symbolic logic and pattern recognition.
