Resource Parameters

Use resource parameters to define changeover-related and constraint-related aspects of a resource. To manage resource parameters, open the actions menu for an organization and click the Resource Parameters option.

Define Resource Parameters

Note:

You can use the default parameter values listed at the end of this topic.

1. On the Resource Attributes page, click Add.

2. Select the work center.

3. Select a resource.

4. Select a constraint mode.

   • If you select Constrained, the solver will respect both calendar events and resource capacity constraints.

   • If you select Relaxed, the solver ignores calendar events and resource capacity constraints.

   • If you select Relaxed for capacity only, the solver will respect only calendar events.

5. Select the changeover calculation type.

   • Use Concurrent when multiple attribute changes need to occur simultaneously. The solver will consider the maximum duration of all attribute-based changeover rule durations.

   • Use Sequential if multiple attribute value changes need to happen in sequence. The solver will consider the sum of all attribute-based changeover rule durations.

6. Select the changeover position.

   • Use Cleanup if attribute-based changeovers on the resource should happen when an operation ends.

   • Use Setup if attribute-based changeovers on the resource should happen before an operation begins.

7. Specify whether the horizon start date and time must be enforced.

   • When Enforce horizon start is enabled, all work order operations will be scheduled to begin after the horizon start.

     Note:

     This preference will be overridden if the solver was configured to respect firm work orders in the Schedule Options UI.

   • If you disable it, then firm work order operations can be scheduled to begin before the horizon start.

8. Specify whether the user-defined attribute sequence will be applied.

   • If you enable Apply user-defined attribute sequence, the solver uses the attribute sequence you defined using the resourceAttributeSequences REST service.

   • If the setting remains disabled, the solver devises an attribute sequence.

   • For the user-defined sequence to be applied, the schedule must be configured to use scheduling buckets using the Schedule Options UI.

   Tip:

   Apply the user-defined sequence to a single stage in the production process, preferably to a bottleneck stage.

9. Specify the schedule visualization of resources with more than one default units in the Gantt chart.
   • If the Display Resource Units in Gantt Chart checkbox is selected, you can view the resource usage levels of that particular resource, and individual work order operations that are scheduled on that resource.
   • If the Display Resource Units in Gantt Chart checkbox isn’t selected, you can view only the aggregate resource usage levels in Gantt chart.
10. Specify the Grouping Attribute for Changeover Reduction. Production Scheduling uses this attribute to group operations with same attribute value for changeover reduction and works with the advanced schedule option Look Ahead Window in Days. This is only considered when the user-defined attribute sequence functionality isn't used.

If you don't configure parameters for any resource in your schedule, the following default values will be considered:

• Changeover Calculation: Concurrent

• Changeover Position: Setup

• Constraint Mode: Relaxed

• Horizon start date: Enforced

• User-defined attribute sequence: Not considered
