Charles River Analytics Inc., developer of intelligent systems solutions, has received additional funding from the US Navy to extend and enhance our Distributed Analysis Tool for Enterprise Monitoring (DATEM) full-scope prototype. DATEM is a real-time alerting system that provides tripwires to detect, classify, and localize system faults. DATEM identifies inappropriate operator behaviors (e.g., failure to respond to critical system alerts), recognizes emergent conditions of interest (e.g., hardware or software faults, resource limits), and recommends appropriate responses to improve mission’s success. DATEM makes sense of health and status data and alerts Sailors of abnormal system behavior. The DATEM contract with options is valued at ~$1.5 million over four years.
DATEM provides understanding for health and status to ensure systems are functioning properly, such as antennas and other naval systems
The Navy has developed numerous net-centric information systems that support fleet operations. Adverse operational conditions, operator behaviors, and routine wear all affect the availability and performance of these systems. For example, high temperatures may lead to a part failure that degrades performance. Worse, some failures are very difficult to detect and classify. These conditions challenge Sailors’ ability to respond rapidly and effectively to failures and maintain mission readiness.
“It’s extremely humbling—and very exciting—to know DATEM will be used daily by the Navy,” explained Joe Gorman, Charles River’s Principal Investigator on the DATEM effort. “Our system also provides an opportunity for us to apply our latest and greatest machine learning research for fault detection and classification with probabilistic modeling for fault localization. The combination of fault detection and localization technologies improves efficiency and makes DATEM valuable to the Navy.”
In our prior research, we delivered an automated fault classifier that significantly improved the efficiency and accuracy of previous semi-automatic fault analysis approaches. Then, we used models to automatically localize sources of failure to field replaceable units. These models drastically reduced the time it takes for Sailors to discover and resolve faults.
DATEM is another successful application of Figaro™, our probabilistic programming language. While DATEM is currently available to provide real-time fault detection and localization to ship support specialists, Figaro will allow us to significantly improve the effectiveness of its fault localization feature.
