Integrated Logistics Intelligence System (ILIS) is a system that provides comprehensive maintenance, anomalies detection, fault-prediction, and supply chain management for Uncrewed Surface Vessels (USV). ILIS gathers real-time data from the USV’s systems to help maintainers diagnose issues, order replacement parts, and plan maintenance more efficiently. It aims to increase the USV’s availability and reduce operational and maintenance costs. ILIS can be used to aid users in maintenance scheduling, mission planning, debriefing, and training activities, providing an aggregated readiness awareness for users.
