This page enables you to review the constraints of the plant's planning capacity and pull forward.
Before you start
Use the right-hand context selector dropdown to select a location.
Exception Event Review Bar Chart
The bar chart represents EF Hours Pulled Forward, EF Hours Reduced, Hours Needed, Pull Forward Capacity Usage, and Hours Available.
Summary View
This chart provides the holistic view of the Constraint Event, Maximum Utilization (%), Pulled Forward Capacity Utilization (%), Simulated Max Pulled Forward Capacity Utilization (%) and Unconstrained Capacity Utilization (%).
Select the Hide Pull Forward checkbox. And/Or select the Hide Capacity Shortfall checkbox.
Parameters
Parameters | Values |
Max Pull Forward Periods | The maximum number of periods for which excess demand can be pulled forward. |
Yellow | The percentage of usage over which the value is highlighted in yellow. |
Red | The percentage of usage over which the value is highlighted in red. |
Utilization Percentages
This graph and table displays the utilization percentages for the value selected in the context selector dropdown below the table.
Parameters | Values |
Unconstrained Capacity Utilization (%) | The usage capacity is calculated as (Demand − Production Load) / ((Hours Available − Factory Calendar) ∗ (Run Rate − Run Rate per Product)). |
Simulated Max Pulled Forward Capacity Utilization (%) | The demand is pulled forward, so the previous period's use is 100%. |
Pulled Forward Capacity Utilization (%) | This is based on the finalized pull forward by the supply planner. |
Plant Constraint Utilization Chart | Provides a concise view of the Constraint Event, Maximum Utilization, Unconstrained Capacity Utilization (%), Simulated Max Pulled Forward Capacity Utilization (%), and Pulled Forward Capacity Utilization (%). |
Constraint Events
A constraint event is created when the supply planner wants to pull forward demands, to ensure the usage is within the limits of the production constraints.
Parameters | Values |
Event Name | The name of the exception. |
Process | The plant and production process where the constraint event is created. |
Start Period | The period when the exception starts. |
Ending Period | The period when the exception ends. |
Max Pull Forward Periods | Enables the supply planner to edit the number of periods that demand can pull forward per exception. |
Effective | When enabled, the constraint event becomes effective. |
Exception Event Review
This table and graph shows information across the shortfall period and the maximum pull forward period.
Parameters | Values |
Period | The pull forward and shortfall time periods. |
Hours Needed | The hours needed to satisfy the demand for the week. Hours Needed = (Demand − Production Load) / (Run Rate − Run Rate per Product). |
Hours Available | Total number of hours available at the factory for producing the product based on the Factory Calendar. |
Capacity Shortfall | This is the Hours Needed value minus the Hours Available value. |
Effective Hours Reduced | The hours reduced by pulling forward the demand. Ideally, the capacity shortfall should be equal to the hours reduced. |
Remaining Capacity Shortfall | Capacity Shortfall – Effective Hours Reduced. When zero, all the demand is met by pulling forward the forecast. |
Target Usage Pull forward | Based on simulated pull forward usage calculations. |
EF Hours Pull Forward | The planner approved pulling forward hours. |
Remaining Target Usage to Pull Forward | The available capacity for the week at the plant. Calculated as Target Usage Pull Forward - EF Hours Pull Forward. |
Pulled Forward Capacity Usage | Hours Needed + EF Hours Pull Forward. |
Pulled Forward Capacity Utilization | The usage calculated based on the pull forward demand. |
Steps
Automatically Add Capacity Shortfalls as Events
To automatically add events when utilization > 100%:
- Select Add Capacity Shortfalls as Events.
Manually Add Capacity Shortfalls as Events
- Select Add Constraint Events.
- Specify the Parent, Event Name, Process, Start Period, and End Period.
- Select Submit.
The event is created in the Constraint Event panel.
Delete Capacity Shortfalls as Events
- Select the Delete option against the events to be deleted.
- Select the Delete Constraint Event.
Updating Pull Forward Demand
The table is used to create a pull forward plan based on reviewing the constraint event.
- Identify the number of units to pull forward from the capacity shortfall and run rate.
- Enter the pull forward quantity in the Reduce Units (U) field.
- Check the available capacity in the previous periods (pull forward periods) from the Pull Forward * Run Rate.
- Select the pull forward plan. This enables you to assign additional demand across previous pull forward periods.
- Check the resolving constraint event graph to verify that the Utilization After Constraint (%) is greater or equal to Maximum Utilization (%).
