Working with Premises

When working with Premises, you can define production demand and shift model information on systems.

This task shows you how to:

Before you begin: Your session content must include Manufacturing Assembly and System structures.

Open Content and Check Configurations

The manufacturing assembly must have a configuration context and at least two predefined configurations.

  1. Open your content in Process Planning.


  2. Right-click the manufacturing assembly in the tree and select Properties.
    The Properties dialog box shows the context and the configurations defined on this manufacturing assembly.



  3. Right-click an operation under System1 in the tree and select Properties.
    The Properties dialog box shows the effectivity expression defined on this operation.



    Other operations have different effectivity expressions depending on the required configuration.



Define Production Demand

You can define the production demand to represent the quantity to be manufactured for a number of items and configurations.

  1. Right-click a System and select Premises Definition > Define Production Demand.
    The Production Demand Definition panel appears.
  2. Click Add New Production Demand to initialize a new production demand.
  3. Define the required time period using the Time Unit list.
  4. Click Detailed to select the Detailed mode.
  5. Click Add Item to Production Demand and select an item in the tree.

    The selected item must have defined configurations.

    A item area is added to the panel, which enables you to specify configurations and quantities.
  6. Select the required configuration using the list.
  7. Enter a quantity for the configuration.
  8. Click Add Configuration to select a new configuration.
  9. Enter a quantity for the configuration.
    The Production Demand Definition panel is updated with this information.



  10. Close the Production Demand Definition panel to save your definitions.

Define a Shift Model

You can define shift models to store information of the shift schedule. The shift model allows calculating an aperture time of the system. This aperture time can be linked to a production demand to compute the required cycle time of the system.

  1. Right-click a System and select Premises Definition > Define Shift Model.
    The Shift Model Definition dialog box appears.
  2. Add a shift model by clicking New Shift Model .
  3. Rename the shift model.
  4. Modify the schedule length (for example, 7 days).
  5. Click Add Shift to add shifts to the table.
  6. Modify the shifts (for example: duration = 8 hours, occurrence = 5 times, allowance = 80%)


  7. Create other shift models in the same way.
  8. Close the Shift Model Definition dialog box to save your definitions.

Manage Premises Usage with Workload Balancing

You can use the Premises Usage command to manage planning premises, if there is at least one production demand and one shift model defined on the system. When the premises usage criteria is applied, the result can be visualized on the Workload Balancing panel.

  1. Select the System Root and click Workload Balancing .
    The Workload Balancing panel appears.



    Each column in the bar chart represents a system: the operations in each column are represented by blue rectangles. The table under the bar chart shows information for each system. Cycle Time is the cycle time of the root system. For more information, see .

  2. From the action bar, click Premises Usage and select the required item.
    The Premises Usage panel appears. It shows a production demand, a shift model, and the computed cycle time corresponding to that criteria.



    You can select a different production demand and shift model using the lists.

  3. Click Apply in the Premises Usage panel.
    The Workload Balancing panel is updated according to the premises usage criteria.

    An additional orange horizontal line in the Workload Balancing panel to indicate the computed cycle time according to the premises usage criteria. The cycle time of the selected system is not modified in this case.



    Note: Cycle Time in the table is the cycle time of the root system and its subsystems.
  4. Optional: Click Set Computed Cycle Time in the Premises Usage panel .
    The computed cycle time is stored on the current selected system (in this case, the root system and its subsystems).

    For more information, see .
