Costing Output Statistics

ProModel collects costing statistics only if you uncheck the Disable Cost Statistics option in the Simulation Options menu (see Enable or Disable Costing). Included in the General Statistics Report, ProModel calculates costing statistics.

Locations

• Operational Cost = (Active Operation Time * Rate) + (Any IncLocCost)

• % Operational Cost refers to the location’s percentage of the sum of all operation costs

• Resource Cost = (Utilization * Rate) + (Times Used * Cost per use)

Please note

For Resource Cost, Utilization and Times Used refer to the utilization of a resource while at a location. This applies only to resource use through operation logic.

• % Resource Cost refers to the location’s percentage of the sum of all resource costs

• Total Cost = (Operation Cost + Resource Cost)

• % Total Cost refers to location’s percentage of the sum of all location costs

Resources

• NonUse Cost = (1-% Utilization) * Scheduled Time * Rate

• % NonUse Cost refers to the resource’s percentage of the sum of all nonuse costs

• Usage Cost = (% Utilization * Scheduled Time * Rate) + (Times Used * Cost per use)

• % Usage Cost refers to the resource’s percentage of the sum of all resource usage costs

• Total Cost = Usage Cost + NonUse Cost

• % Total Cost refers to the resource’s percentage of the sum of all resource costs

Entities

• Explicit Exits The number of entities that have explicitly exited. Whenever an entity exits the system, it is an explicit exit except in the following cases:

- When an entity JOINS, permanently LOADS, or COMBINES with another entity, it implicitly exits the system, and is reported as an exit in the Entity Activity report. However, for costing purposes, the entity did not explicitly exit, but its costing information was added to the entity it was JOINED, permanently LOADS, or COMBINED with.

- When an entity temporarily LOADS or GROUPS with another entity, and the entire LOADED or GROUPED entity exits the system, the original entity implicitly exits the system, and is reported as an exit in the Entity Activity report. However, for costing purposes, the original entity did not explicitly exit, but its costing information was added to the entire load or group.

• Total Cost Dollars Total Cost = cumulative entity cost, or the sum of costs incurred on all locations the entity passed through + the sum of all costs incurred by use of resource + initial cost + any IncEntCost

• % Total Cost % Total Cost refers to the entity’s percentage of sum of all entity costs

In the above calculations, the rate defined (per day, hour, minute, and second) converts to the default time units specified in the General Information dialog.

Please note

ProModel does not allow you to generate a Costing Graph. However, if you set a variable equal to GetCost (e.g., Var1=GetCost), you can generate a time series graph to track changing entity costs. See GetCost() for more information.
