Proactive Fault Handling for System Availability Enhancement

Proactive Fault Handling for System Availability Enhancement
Proactive fault handling combines prevention and repair actions with failure prediction techniques. We extend the standard availability formula by five key measures: (1) precision and (2) recall assess failure prediction while failure handling is gauged by (3) prevention probability, (4) repair time improvement, and (5) risk of introducing additional failures. We give a short survey of actions that are suited to be combined with failure prediction and provide a procedure to estimate the five key measures. Altogether, this allows to quantify the impact of proactive fault handling on system availability and may provide valuable input for system design.
