Context Dependent Prognostics and Health Assessment: A New PAradigm for Condition - Based Maitenance

In today's military environment ships, systems, and equipment are being asked to perform at levels not thought possible a decade ago. The intent is to improve process operations and equipment reliability, availability, and maintainability without costly upgrades. Of course, these gains must be achieved without impacting combat readiness. Downsizing is also taking its toll on operations. Loss of personnel, particularly those who represent the corporate history, is depleting the Navy of its valuable experiential base which has been so heavily relied on in the past. These realizations are causing the Navy to rethink its condition-based maintenance policies, moving them away from reacting to equipment problems to taking a proactive approach to anticipate needs based on mission requirements. This SBIR will develop a new approach to condition-based maintanance-Context Dependent Prognostics and Health Assessment. This advanced diagnostics capability will be developed around a context dependent model that provides a capability to anticipate incipient system/element failures and determine machine performance over a protracted period of time. This prognostic capability will link mission requirements to an economic performance model. In this context, a system may provide 100% operability with less than 100% functionality. This new paradigm will be integrated into the Navy enterprise system to facilitate optimal logistic supply and support.
