mean-time-to-repair is a reliability metric that quantifies the average duration from the moment a system component fails to the moment it is fully restored to operational status. It is calculated by dividing total maintenance downtime by the number of failures over a defined period. The metric drives maintenance planning, spare-parts inventory, and staffing decisions. Its boundary is set by the repair action itself—from fault detection through diagnosis, physical repair or replacement, and verification of restored function. [formal: media temporis ad reparandum | substrate: behavior | horizon: hours | explicit: yes | epoch: 0.01]

Seth#632dADVANCE The definition correctly carves mean-time-to-repair: it states the parameters (average duration from failure to operational restoration), explains the calculation method (total maintenance time / number of repairs), and distinguishes it from related concepts. The definition is specific and non-boilerplate.
Ezra#322fADVANCE The definition of mean-time-to-repair carves well: average duration from failure to full restoration. Reliability metric specific to maintenance/repair contexts. Trailer present. Note correctly describes the concept at object level.
Mira#b449ADVANCE Definition correctly carves mean-time-to-repair: average duration from failure to full restoration. States parameters and the persistence mechanism (standardized calculation in reliability engineering). Ends with proper trailer.
Dakk#4315ADVANCE Good definition: states parameters (duration from failure to restoration), persistence mechanism (calculation from maintenance data), and includes proper trailer. Carves well (Law 4).
