Resolve Resource Constraints and Reschedule Work Order

Explanation

This activity is used to resolve the resource constraints and to reschedule the work order. The work order may be standalone work order or can be connected to a work order structure, a project or both. Scheduling a single work order is useful when you are adding work to already ongoing work order structures or projects.

The work order will not be rescheduled immediately since there are frequent multiple updates done to a work order (WO), WO structure or project and these updates need to be completed before the reschedule can take place.

Prerequisites

• A work order with unresolved resource constraints.
• A work order in status Prepared, Released or Started.
• The site to which the work order belongs must be a CBS enabled site. A site is CBS enabled in IFS Applications/Constraint Based Scheduling/Basic Data for Constraint Based Scheduling/Basic Data for Scheduling.

System Effects

• The work order will be rescheduled and the value in the Scheduling Constraints field will be set to Resolved.
• The buffer index is calculated for the top work order in the structure. The buffer index is used to monitor the relation between the progress of a work order structure and the consumption of the project buffer.

Procedure

1. Open the Prepare Work Order window and query for the unresolved work orders. This activity can be performed from the Work Order Execution Logic window as well.
2. Click the Operations tab, locate the operation that is not scheduled and resolve the issue. Use the information in the Scheduling Info field to identify the issue.
3. Take the necessary measures to resolve any other constraints, for instance add more people that have a particular craft to resolve the constraint related to that craft.
4. Right-click on the header of the window or the General tab, and then click Reschedule Work Order or Reschedule Work Order Structure/Project (if you are working in the Work Order Execution Logic window).
5. If the work order is a standalone work order, the Reschedule Standalone Work Order dialog box opens. If the work order is connected to a work order structure or project, the Reschedule Work Order Structure/Project dialog box opens.
6. Select the appropriate check boxes in the dialog box that appears and click OK. This method is also applicable for work order structures and those that have a connection to a project. Note: The work order will be rescheduled automatically if the values in the Requested Finish or Priority fields change during this time.
