Architecture and Tool for Self-Evolving Maintenance and Operations Reasoning

Impact Technologies, with the support of Lockheed Martin, proposes to develop and demonstrate a model-based software for the design and development of a Self-Evolving Maintenance Reasoner for PHM systems. Impact Technologies will develop and demonstrate a web-enabled software tool set, including advanced maintenance reasoning technologies within an open-systems software architecture, to support a comprehensive Self Evolving Maintenance and Operations Reasoner or SEMOR. The development and integration effort will consist of many elements, ranging from model-based reasoning to OSA-CBM interface development, with various sources of data, information and knowledge being considered to obtain a truly intelligent and evolvable 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 PHM, FMECA, sensor, and maintenance information. In addition, the open systems architecture (OSA) and associated software interfaces to existing JSF asset management systems (i.e ALIS) and PHM software containing pertinent maintenance and logistics management information will be addressed. Most importantly, the SEMOR system will employ a combination of case-based and Bayesian processes to evolve the underlying Maintenance Integrated Model (MIM) when given maintainer feedback. The SEMOR system will be demonstrated on one of many JSF PHM applications Impact is involved in including the drivetrain clutch, actuation hardware, and power and thermal management systems.
