Abstract

This paper describes technical progress made in maturing ISHM technologies for hybrid diagnostic reasoners under NASA\´s Exploration Systems Research & Technology (ESR&T) program by Northrop Grumman Corporation and its NASA partners at ARC, GRC, JPL, and JSC A layered architecture was developed that supports both distributed and hierarchical reasoning as well as interoperability and interchangeability of reasoning algorithms. A hybrid reasoner using this architecture was to be demonstrated performing automated fault detection and isolation in an "Apollo 13" - like failure scenario
