Systems Engineering Processes for the Acquisition of Prognostic and Health Management Systems

Abstract

Prognostic and Health Management (PHM) systems often experience delayed fielding and lengthened maturation cycles due to their relative immaturity and the fact that they are regarded as non-flight critical systems. The national fiscal crisis and rising debt of the U.S. have each placed increased scrutiny on military systems acquisition and procurement practices. The Defense Department is pushing for greater emphasis on fundamental systems engineering practices earlier in the acquisition phase, with the expectation of fewer schedule slips and budget overruns. The acquisition of PHM systems could also benefit from increased systems engineering rigor early in their development. A 2007 directive from the DoD states that PHM systems be implemented into current weapon systems equipment, and materiel sustainment programs where technically feasible and beneficial. This research examines the definition of PHM requirements and a method for developing a solution neutral architecture for PHM systems. The thesis also identifies software development practices and acquisition processes for military propulsion PHM systems. The conclusion of this research is that the Defense Department can deliver the warfighter a capable PHM system on-time and within budget through the establishment of better procurement and systems engineering practices.
