The following image displays an example of the Total Cost graph.
Note: If you prefer to see the various cost categories added together and presented in a single column for each Scenario, in the upper-right corner of the Summary section, select the Show Total check box.
The categories in the Total Cost graph are calculated for each Scenario as described here:
- Action Cost: The average Action cost across all the iterations. Action cost includes any materials or personnel needed to complete any Actions that exist in the Scenario and any Resources used to complete the Actions. The following fields are used to calculate Action costs:
- System Action record: Action Cost.
- System Resource record: Fixed Cost, Variable Cost, and Variable Cost Units.
- System Resource Usage record: Duration, Duration Units, and Quantity.
- Lost Production Cost: The average lost production cost across all iterations. Lost production cost includes the cost of lost production for any element when it is stopped or unable to run, according to the value in the Lost Product Cost field of the record that represents that element.
- Planned Correction Cost: The average planned correction cost across all the iterations. Planned correction cost includes the cost to repair an element that is identified as having a potential failure by an inspection or condition monitoring Action and any Resources used. The following fields are used to calculate planned correction costs:
- System Subsystem record: Variable Cost, and Variable Cost Units.
- System Asset record: Variable Cost and Variable Cost Units.
- System Switch record: Variable Cost and Variable Cost Units.
- System Risk record: Planned Correction Cost, Planned Correction Duration, and Planned Correction Duration Units.
- System Resource record: Fixed Cost, Variable Cost, and Variable Cost Units.
- System Resource Usage record: Duration, Duration Units, and Quantity.
- Unplanned Correction Cost: The average unplanned correction cost across all the iterations. Unplanned correction cost includes the cost to repair any failed element and any Resources used to do so. The following fields are used to calculate unplanned correction costs:
- System Asset record: Fixed Cost, Variable Cost, and Variable Cost Units.
- System Switch record: Fixed Cost, Variable Cost, and Variable Cost Units.
- System Risk record: Fixed Unplanned Correction Cost, Variable Unplanned Correction Cost, and Variable Unplanned Correction Cost Units.
- System Resource record: Fixed Cost, Variable Cost, and Variable Cost Units.
- System Resource Usage record: Duration, Duration Units, and Quantity.
