MTBM Calculations Page
Under FRACAS in the Calculate window, the MTBM Calculations page provides for applying different filters to the MTBM (mean time between maintenance) calculation to compute as many as 10 different variations of MTBM calculations. For example, you can compute the MTBM for replacement maintenance actions or maintenance actions that cost more than a specified amount. For more information, see MTBM (Mean Time Between Maintenances). By default, all calculations are cleared. You can click the Select All button or Clear All button to select or clear all calculations and then customize your selections from there.
The following table describes the table columns on the MTBM Calculations page.
