Oracle Enterprise Asset Management (eAM) shares the Scheduler Workbench, used in Oracle Manufacturing, to schedule Work Orders and operations.
The Scheduler Workbench enables a planner to graphically view and reschedule Work Orders. It provides you with a visual display of Work Orders, Operations, and Resources. You can interactively reschedule Work Orders, operations, and resources
by dragging and dropping them at a new date and time. Any precendence or sequencing requirements defined for the Work Order are displayed and maintained during scheduling changes. Resource availability and requirements may display so that you can graphically view the impact of scheduling changes.
Note: You have Oracle Manufacturing’s Constraint Based Scheduling available to you, if your company has purchased the appropriate license. If you do NOT have this license, you automatically have the Infinite Scheduler available to you; this
scheduler is not constraint-based.
A constraint-based scheduling engine schedules asset Work Orders and operations’ scheduled dates, resources, and material constraints. The scheduling process calculates Work Order and operation scheduled durations and dates, based on the forward or backward scheduling goal, and Work in Process parameters. The concurrent program is triggered after a Work Order is released. The Work Order automatically transitions to a Pending Scheduling status, until the concurrent program finishes scheduling. At that time, the Work Order transitions back to a Released status.
Using the Scheduler Workbench
You can use the Scheduler Workbench to select specific work orders, expand, and collapse work orders and operations using a tree hierarchy structure. A Gantt Chart graphically displays both firmed and unfirmed work orders. You can view and update start and end dates for each resource.
In manual mode, the only constraints are operations, and they do not surpass work order dates. In automatic mode, the Scheduler process creates start and end times for operations and resources. By default, you are in manual mode.
To use the scheduler workbench
1. Navigate to the Scheduler Workbench.
2. Select Filter to narrow down the information displayed. You can display information by Department, Resource, Asset Information, filter by time, or a combination of this information. You can view information for work orders at a
3. Choose Apply, and then OK to filter information entered. Work Orders appear on the left side of the window, with their associated operations’ resources, in a tree hierarchy format. On the right, bars spanning between calendar days represent associated schedules for the current operation resources. If dependent operations exist, you can see dependency links; the
Scheduler process considers these dependencies. You can drag and drop the bars between different calendar days to dynamically adjust schedules.
4. Optionally, firm or unfirm Work Orders by selecting Create/Modify Work Orders from the Tools menu. The Find Work Orders window appears. You can also right click on a schedule, symbolized by a bar.
