Define formulas used to calculate equipment performance. A formula consists of four variables that include condition, capacity, MTBF (mean time between failure), and MTTR (mean time to repair), and up to six user defined variables. Each variable is assigned a weight which determines how much it contributes to the overall performance of the equipment.
Performance is a number between 0 and 100, where 0 is poor performance and 100 is best performance.

-
Specify this information:
Performance Formula - Select the performance formula to use to calculate equipment performance.
Description - Specify a description for the performance formula
Organization - Specify the organization for the performance formula.
Class - Specify the class for the performance formula.
Status - Specify the status of the performance formula, such as Unfinished, Request Approval, or Approved.
-
Specify this condition and capacity details:
Capacity Rating Weight - Specify a weight for the capacity rating from 0 to 1.
Condition Rating Weight - Specify a weight for the condition rating from 0 to 1.
Capacity Code - Specify the capacity code for the performance formula.
-
Specify this information for the MTBF and MTTR details:
MTBF Rating Weight - Specify the weight that must be assigned to the MTBF (mean time between failure) Rating of the equipment.
Maximum Allowable Failures per Year - Specify the maximum number of failures allowed per year.
Include Children - Select this check box to include the children of the equipment.
Usage Based - Select this check box to calculate the number of failures relative to the usage of the equipment. For example, for a bus it may be more relevant to know that there are 10 failures per 10000 miles than 10 failures per year.
At Usage per Day - Specify the usage per day and the At Usage per Day UOM for the performance formula.
MTTR Rating Weight - Specify the weight that must be assigned to the MTTR (mean time to repair) Rating of the equipment.
Maximum Allowable Repair Hours - Specify the maximum number of hours allowed for repair.
Repair Time Calculation - Specify the calculation for determining the repair time.
Use Downtime Hours if Present - Select this check box to use downtime hours for repair if available.
-
Optionally, specify this information for these variables:
You can set up the use of six configurable parameters and weights to include in the
performance calculations. All variables work the same way.
Variable 1 Rating Weight - Specify the weight that must be assigned to the Variable 1 Rating of the equipment.
Variable 1 Query - Specify the query for the first variable.
Best Acceptable Result 1 - Specify the best acceptable result for the first variable.
Worst Acceptable Result 1 - Specify the worst acceptable result for the first variable.
