Localization is the process of restricting a failure to a subset of possible causes. Confirmation is the process of validation that a failure/fault has occurred, the filtering of false alarms, and assessment of intermittent behavior. PHM consists of ‘on-board’ as well as ‘off-board’ components.ĩ Some Definitions Diagnostics - The identification of a fault or failure condition of an element, component, sub-system or system, combined with the deduction of the lowest measurable cause of that condition through confirmation, localization, and isolation. Prognostics is the process of calculating and reporting an estimate of remaining useful life for a component, within sufficient time to repair or replace it before failure occurs.Ĩ Some Definitions Prognostic Health Management (PHM) – The implementation of an integrated software and hardware system which monitors the health, status and performance of a vehicle or system, tracks consumables (oil, batteries, ammunition, filters, fuel, coolant…) and configuration (software versions, part history…), and determines remaining life of all safety and performance critical components, predicting failures before they occur, thereby enhancing logistics and maintenance activities. Army’s Future Combat Systems are: Reducing the Logistics footprint Increasing Availability Reducing total cost of ownership Implementing Performance Based Logistics Improvements in the ‘ilities’ (RAM-T) Reliability Availability Maintainability Testability Supportabilityħ Some Definitions Prognostics - Of or relating to prediction a sign of a future happening a portent.
