Neuro-Cognitive Maintenance Support System for Legacy INS in Submarines

The overall goal of the Neuro-Cognitive Maintenance Support System for Legacy INS in Submarines (NeuroCm-INS) is to optimize INS maintenance operations by determining the most likely corrective actions with the use of enhanced diagnostic technologies. At one level, novel technologies are used for determining maintenance paths and conducting root cause analysis under constraints for time and likelihood of success when applying corrective actions. This high level layer is then complemented by a neuro-cognitive troubleshooting scheme that accomplishes the detection and identification of faults. A distinctive characteristic of the proposed system is the performing of INS troubleshooting by new state-of-the-art inference mechanisms with embedded dynamic self-learning that handles newly emerging uncharacterized failures. Altogether, the NeuroCM-INS system enables: (1) advanced failure detection and identification with learning of new faults; (2) maintenance path optimization using maintenance and diagnostic data; and (3) automated aids based on graphical software embedded within portable devices for use by on-board personnel. The technology will benefit the Navy by reducing the Mean Time to Repair.
