Systems Availability Metrics
This book illustrates formulation and evaluation of systems availability describing methods of measuring systems availability from maintanance data
Availability is a reliability metric that quantifies the proportion of time a system is operational and ready to perform its intended function. It takes into account both scheduled and unscheduled downtime. By measuring availability, systems engineers can identify critical bottlenecks and optimize system performance to maximize uptime.
Practical case study is drawn from an ATC system providing aerodrome control service via 6 equipment. The availability of aerodrome control service is the integral summation of availability of individual equipment constituting the system Availability metrics measure the uptime and reliability of a system. This metric is particularly important for mission-critical systems that need to operate continuously. Systems engineers use availability metrics to identify potential failures, implement redundancy measures, and ensure high system reliability.
