MTTR Mean Time To Repair

 

Be Prepared

MTTR (Mean Time To Repair / Replace) is an important parameter for maintainability planning and optimization.

BQR’s MTTR software allows you to define the repair / replace steps for each component and assembly in a hierarchic tree, and to calculate MTTR for each level.

By reviewing the repair steps you gain insight regarding the required support equipment, staff, and time for repair / replace tasks.
