The results of the individual equipment then roll up to category level if the equipment has a category filled in, a record for this category exists on the Equipment Class Definition screen, and the organization of this record matches that of the equipment. These attributes are calculated or populated on category level:
|
Field |
Calculation |
|---|---|
|
Condition Rating |
Average Condition Rating of all equipment in the category. |
|
Capacity Code |
Copy of the Capacity Code from the selected performance formula. |
|
Available Capacity |
Sum Available Capacity of all equipment in the category. System adds the calculated Available Capacity of all equipment with the same Performance Formula as the Equipment Class Definition record and with a more recent Performance Last Updated than the Date Approved on the selected formula. But since not all equipment may have been calculated or may have been calculated with the same formula or revision of the formula, the system also adds Available Capacity for this equipment. |
|
Desired Capacity |
Current Total Desired Capacity for the Class/Category for the Capacity Code associated to the selected class/category record (equipment class definition record). Search on Category first if present. If blank or no record is found, then search on Class level. |
|
Capacity Rating |
Available Capacity / Total Desired Capacity * 100 To not negatively impact performance, the system will set this to 100 if Available Capacity or Total Desired Capacity or both are blank or if Total Desired Capacity is zero or if the calculated Capacity Rating is > 100. |
|
Number of Failures |
Average Number of Failures of all equipment in the category. |
|
MTBF (Days) |
Average MTBF (Days) of all equipment in the category. |
|
MTBF Rating |
Average MTBF Rating of all equipment in the category. |
|
MUBF |
Average MUBF of all equipment in the category. If the Meter Unit on the equipment does not match At Usage Per Day UOM of the selected formula, the system will convert the equipment data first. If no conversion factor is found the equipment will be excluded. |
|
MUBF Rating |
Average MUBF Rating of all equipment in the category. |
|
MTTR (Hours) |
Average MTTR (Hours) of all equipment in the category. |
|
MTTR Rating |
Average MTTR Rating of all equipment in the category. |
|
Variable 1 Result |
Average Variable 1 Result of all equipment in the category. |
|
Variable 1 Rating |
Average Variable 1 Rating of all equipment in the category. |
|
Variable n Result |
Repeat for variables 2 through 6. Similar Variable 1 Result. |
|
Variable n Rating |
Repeat for variables 2 through 6. Similar Variable 1 Rating. |
|
Performance |
Similar calculation as used on equipment level. |
|
Equipment Count |
Count all equipment in the category with the same organization as the Equipment Class Definition record and with a status unequal Withdrawn and unequal Awaiting Purchase (System status codes A and D). |
|
Equipment Included in Performance |
See Equipment Count above. Additionally, only include equipment with the same Performance Formula as the Equipment Class Definition record and with a more recent Performance Last Updated than the Date Approved on the selected formula to ensure that only results based on the current approved version of this formula are included in the category level numbers. |
|
Performance Last Updated |
Set equal to system date/time. |
Note that the system may create an equipment class definition record automatically for the category. All averages are only calculated for the equipment that determined the Equipment Included in Performance field. See above for the selection criteria relevant to that field.
