Using alternative work units that run slower that the primary work unit.

Problem:

I have set some alternative groups for work units that are interchangeable. There are however some stock code that, if run on alternative work units, runs slower. Is there a way to accommodate this without having to manually extend or edit each operation?
 

Solution(s):

Yes. Constraints may be utilised for scenarios whereby work units run at different rates than the primary work unit specified in the routing. To accommodate the difference when using alternative work units, use constraints to adjust the operation time.  In this example the alternative work unit runs slower than the specified work unit by a factor of 1.5.  Product specific constraints can be set up within any declared Global constraints.  These code/operation specific time settings replace the values declared in the original routing and are used within APS in conjunction with the Global constraint multiplication factors.

To define a new Product constraint

1. Select the Global constraint that the product constraint is going to be associated with
2. Click the "Product Number - Operation Description" tab
3. Click "Add New"
4. Enter product number (or use the search function next to the text box)
5. Enter the Operation Description if the constraint is to be operation specific  (if left blank, all product number operations completed within the global constraint will adopt the constraints set here)
6. A variety of options are available for constraint settings - Set as required.
7. Click OK
8. To make changes, click on the Edit button alongside the appropriate Constraint Type for the the selected constraint.
