Consider Shift Exceptions in Scheduling

As a scheduler, it’s important to consider various shift exceptions, such as resource overtime, scheduled and unexpected downtimes, changes in labor availability, and fluctuations in resource capacities when scheduling factory resources. Prior to this update, Oracle Production Scheduling applied a constant production capacity across the entire schedule horizon, regardless of any exceptions. With this update, Oracle Production Scheduling now respects a resource's shift exceptions during schedule calculation, resulting in a more accurate and executable schedule.

Before update 24C, Oracle Production Scheduling used the value specified in Default Units Available column on the Work Center Resource page to determine the total number of resource units available across the entire schedule horizon, without considering variations by shift. For example, if a resource ZA-EQP2 had 15 default units available, but had 5 units in SHIFT-A, 12 units in SHIFT-B, and 10 units in SHIFT-C, those shifts' differences were not taken into account.

After update 24C, Oracle Production Scheduling now considers the shift-specific values and any extra exceptions for the work center resource. After refreshing the production schedule, these shift-specific number of units available values are considered as capacity constraints during schedule calculation.

The Gantt chart uses a 10-color scheme to show the units available and units used by work order operations assigned to a resource. Low usage is green and high usage is red. Detailed information is available in tooltips, see Figure 2. For example, if a work order operation consumes 10 units and there are 10 units available during SHIFT-B, they are all used up at that time.

Resource Usage Levels are Indicated via Color Scheme, and the Tooltip Provides Details.

Whenever the Units Available Now or the Units Used Now values change, a rectangular box appears on the parent row of the resource to signify these alterations. Click the expand icon to view the child rows showing the individual work order operations scheduled on the resource. It’s important to note that a single child row doesn’t represent an individual resource unit or instance, as one operation can consume multiple units, as seen in the example mentioned. The assignment of work order operations to child row is solely for visualization purposes and isn’t saved permanently.

The units available values can be visualized in the Gantt chart when the Edit Calendar Events mode is enabled.

Currently, you’re unable to adjust the number of available units for a resource within a shift for simulation purposes.
