A description of CAMCOS, an online real-time computer system for Air Force base-level maintenance planning and control. CAMCOS is designed to provide a high-level capability for critical missions and economical performance during routine operations. The system handles planning, scheduling, dispatching, and control for flight-line, bench, and periodic maintenance on a unified basis that relates maintenance to operational requirements. Job requirements for reported malfunctions and other priority work are matched against resources and are scheduled to meet aircraft recovery targets. As work progresses, the system builds up data on each job. These data are used for planning and controlling the maintenance activity and are saved by the system for subsequent analysis and reporting. 63 pp. Ref.
