Autonomous Prescription of Maintenance Requirements

"Condition Based Maintenance (CBM) has become the Navy's overriding operating philosophy aimed at reducing life-cycle costs while maintaining operational readiness by decreasing maintenance requirements and operating with reduced manpower. To support theCBM philosophy, the Navy needs to be able to deploy appropriate tools for equipment health assessment, diagnostics and prognostics. This requires an integrated framework for the development and evaluation of monitoring, diagnostic and prognosticapproaches against actual or proposed shipboard system designs.To address this need, Foster-Miller Technologies (FMT) proposes to create a model based software framework we call the Integrated Design Evaluation Architecture for Condition Based Maintenance (IDEA/CBM) that will provide a tool for the system designer ormaintenance manager to pull various measurement, diagnostic, and prognostic approaches together and then assess the overall effectiveness of the approaches to provide an integrated assessment of the system's health. The IDEA/CBM supports creation of amodel of a shipboard system against which the effectiveness of an approach can be tested. Once an appropriate set of condition assessment tools has been integrated it can be exported to a shipboard CBM system based on the OSA/CBM open system architecturefor implementation. The IDEA/CBM framework will facilitate the integration of monitoring, diagnostic and prognostic capabilities to
