An Integrated System Design and Maintenance Modeling Tool

During the follow-on Phase II effort proposed herein, Impact Technologies will lead an Integrated Product development Team (IPT) to develop and demonstrate a software tool set, including advanced maintenance reasoning technologies within an open-systems software architecture, to support a comprehensive Prescription-Based Maintenance management System (PBMS). The development and integration effort will consist of many elements, ranging from model-based reasoning to ICAS integration and OSA-CBM interface development, with various sources of data, information and knowledge being considered to obtain a truly intelligent maintenance decision support system. One of the key components of the proposed system, consists of the generic reasoning algorithms and Maintenance Integrated Models (MIM) containing CBM, FMECA, sensor, and maintenance information. In addition, the open systems architecture (OSA) and associated software interfaces to existing Navy enterprise management systems and CBM software containing pertinent maintenance and logistics management information will be addressed. At the conclusion of the Phase II program, the Prescription-Based Maintenance management System (PBMS) will automate and optimize the prescription element associated with diagnostic and prognostic results used to facilitate condition based maintenance (CBM). It is expected that a fully functioning prototype of the PBMS system will be fielded for a Navy gas turbine application in a 24 month timeframe that includes all software and user interfaces as well as complete algorithm functionality. In a anticipated follow-on Phase II Option, feedback from a beta-site installation will be used for the final stages of software validation and maturation in preparation for a fleet-wide system deployment.
