A process and tool for determining the cost/benefit of prognostic applications

Efficient application of prognostics requires the capability to estimate its benefit in specific applications. A cost/benefit analysis process and tool-set to generate such estimates is described. The application of this process and tool to an example application is provided to further illustrate the approach. Inputs to the process are a system description, failure modes and distributions. and implementation cost estimates. The output is a life cycle payoff or cost as well as an assessment of the technical risk of the application. The process and tool was developed for use on the Joint Strike Fighter program. It is currently being integrated into a more complete Boeing cost/benefit analysis model that addresses the complete spectrum of diagnostic and prognostic methods
