Equipment Reliability calculated measures and KPIs
This table shows the Equipment Reliability measures that are calculated and defined as saved expressions.
The expressions are based on sum aggregation.
| Measure | Description |
|---|---|
| Actual vs Plnd Usage – Hrs Pct | The actual usage in hours divided by the planned usage in hours |
| Actual vs Plnd Usage – Meter 1 Pct | The actual usage in meter 1 divided by the planned usage in meter 1 |
| Actual vs Plnd Usage – Meter 2 Pct | |
| Actual vs Plnd Usage – Meter 3 Pct | The actual usage in meter 3 divided by the planned usage in meter 3The actual usage in meter 2 divided by the planned usage in meter 2 |
| Actual vs Plnd Usage – Meter 4 Pct | The actual usage in meter 4 divided by the planned usage in meter 4 |
| Availability in Hrs Pct | The planned usage in hours minus the downtime divided by the planned usage in hours |
| Availability Index | The mean time between shutdowns divided by the sum of mean time between failure and mean time to repair |
| Avg Plnd Usage – Hrs | The planned hours divided by the number of completed work orders |
| Avg Plnd Usage – Meter 1 | The planned usage in meter 1 divided by the number of completed work orders |
| Avg Plnd Usage – Meter 2 | The planned usage in meter 2 divided by the number of completed work orders |
| Avg Plnd Usage – Meter 3 | The planned usage in meter 3 divided by the number of completed work orders |
| Avg Plnd Usage – Meter 4 | The planned usage in meter 4 divided by the number of completed work orders |
| Downtime vs Plnd – Hrs | The downtime hours divided by the planned hours |
| Downtime vs Plnd – Meter 1 | The downtime hours divided by the planned usage in meter 1 |
| Downtime vs Plnd – Meter 2 | The downtime hours divided by the planned usage in meter 2 |
| Downtime vs Plnd – Meter 3 | The downtime hours divided by the planned usage in meter 3 |
| Downtime vs Plnd – Meter 4 | The downtime hours divided by the planned usage in meter 4 |
| Eqpt Lifecycle Util Pct |
The lifecycle usage in hours divided by the total calendar hours Note: The actual usage in meter 2 divided by the planned usage in meterSee the Eqpt Lifecycle Util Pct and Eqpt Util Pct
topic below.
|
| Eqpt Util Pct |
The actual usage in hours divided by the total calendar hours Note: See the Eqpt Lifecycle Util Pct and Eqpt Util Pct
topic below.
|
| Failures Pct | The number of failures divided by the number of completed work orders |
| MTBF | Mean Time between Failures (MTBF) is calculated as the actual usage in hours divided by the number of failures |
| MTBS | Mean Time between Shutdowns (MTBS) is calculated as the actual usage in hours divided by the number of shutdowns |
| MTTR | Mean Time to Repair (MTTR) is calculated as the total planned downtime hours divided by the number of work orders with planned downtime |
| Unavailability Index | The unavailability due to unscheduled events, computed as the unscheduled down time divided by the total down time multiplied by 1 minus the availability index |

These measures cannot be analyzed by using the time dimension.
To allow analysis by different time attributes, expressions for Year, Quarter, and Month are created. The saved expressions use the planning date and sum aggregation.
For these measures to work, one or all of the following should be available as
dashboard filter: Time.Year, Time.Year/Quarter, or Time.Year/Month.
| Measure | Comment |
|---|---|
| Eqpt Lifecycle Pct by Year Eqpt Util Pct by Year |
Analyze using Time.Year |
| Eqpt Lifecycle Pct by Quarter Eqpt Util Pct by Quarter |
Analyze using Time.Quarter |
| Eqpt Lifecycle Pct by Month Eqpt Util Pct by Month |
Analyze using Time.Month |
