Performing a Resource Simulation
Access the Execute Resource Simulation form.
- Simulation Name
Enter a unique scenario-specific name to identify the resource simulation.
- Resource Effectivity Name
Select the set of effectivity date ranges of the resource design that you are using for the simulation.
- Demand Source
Select either demand at capacity or the daily rate as the demand source to use for the simulation.
- Continue
Click to complete parameter fields for the resource simulation.
- Start Date and End Date
Enter the start and end dates for the simulation.
- Efficiency Factor
Adjust this value to further adjust the efficiency estimate of the resources. The system applies this factor to the available resource calculation for all processes on the line.
- Revise Resource
Click to access the Revise Resources form.
- Revise Demand
Click to access the Revise Demand form.
- Execute
Click to run the resource simulation for the time frame between the start and end dates. When the simulation is complete, the system displays the results in a grid by process. If you make changes to resources or demand, repeat the simulation to account for the changes.
- Available Time
Displays the available time after you run the resource simulation. The resource simulation calculates the available time based on the following formula:
Current Quantity × Productivity %× EfficiencyFactor × HE (effective hours per shift)
If the resource is shared, this value reflects the aggregate number of shared resources by resource type. The system displays the time in the work content unit of measure for the scenario.
- Required Time
Displays the required time. The resource simulation calculates the required time based on the selected work content type on the process map. The system retrieves the work content for the process for the item and the resource from the standard sequence of events, the sequence of events, or the actual work content record. To calculate the required time, the system multiplies this value with the quantity of planned-for products, either demand at capacity or the daily rate from the daily plan.
- Utilization %
Displays the percentage of utilization. The simulation calculates the utilization percentage by dividing the required time by the available time. If the result of this calculation for a process is greater than 100 percent, the system generates an error message for that process.
- Available Resource
Displays the number of available resources by process according to the associated resource design. This is the current quantity multiplied by the productivity percentage. If the resource is shared, this value is the sum of all shared resources by resource type. If the resource is dedicated, this field displays the value for that specific resource only.
- Required Resource
The simulation calculates the required time by taking the sum of the required time divided by the sum of the demand. The result is the weighted average of the required time. Then the effective hours for that resource as stated by the line design are divided by the sum of the demand as well. The result is the weighted average of the available operation hours. The weighted average of the required time is then divided by the weighted average of the available hours to determine the required resource.
