Note: Rate-based items are not included in simulation sets.
You can use a simulation set to group multiple capacity modifications for a specific department, resource, and shift combination. When making a capacity modification, you can add a workday, delete a workday or modify the number of capacity units available to the shift.
The following table illustrates how you could use capacity modifications to simulate a ramp-up schedule for a new resource, D1, R4, due to be installed on 07-MAR. In this example, Production can estimate that it will be six weeks before the resource is fully operational. One unit of D1, R4 is assigned to Shift 1 which is available 6 hours/day, 5 days/week.
Capacity modifications are always added to existing capacity. With no capacity modifications the available hours for D1, R4 is 1 x 6 x 5 = 30 hours/week. The capacity modification for 01-JAN to 04-MAR creates additional available hours of -1 x 6 x 5 = -30. The net available hours for the period is 30 - 30 = 0 hours/week. The capacity modification for 07-MAR to 11-MAR creates additional available hours of -1 x 5 x 5 = -25 hours/week. The net available hours for the period is 30 - 25 = 5 hours/week.
Modification | Date From | Date To | Time From | Time To | Capacity Change | Simulation Set |
---|---|---|---|---|---|---|
Modify capacity | 01-JAN | 04-MAR | 06:00 | 12:00 | -1 | Set 1 |
Modify capacity | 07-MAR | 11-MAR | 07:00 | 12:00 | -1 | Set 1 |
Modify capacity | 14-MAR | 18-MAR | 08:00 | 12:00 | -1 | Set 1 |
Modify capacity | 21-MAR | 25-MAR | 09:00 | 12:00 | -1 | Set 1 |
Modify capacity | 28-MAR | 01-APR | 10:00 | 12:00 | -1 | Set 1 |
Modify capacity | 04-APR | 08-APR | 11:00 | 12:00 | -1 | Set 1 |
Table 1 - 1. Ramp-up Schedule for D1, R4 (Page 1 of 1) |
The following table illustrates the impact of the capacity modifications on the net available hours for D1, R4 for the entire ramp-up period.
Date From | Date To | Available Hours | Capacity Modification | Net Hours Available |
---|---|---|---|---|
01-JAN | 04-MAR | 30 | -30 | 0 |
07-MAR | 11-MAR | 30 | -25 | 5 |
14-MAR | 18-MAR | 30 | -20 | 10 |
21-MAR | 25-MAR | 30 | -15 | 15 |
28-MAR | 01-APR | 30 | -10 | 20 |
04-APR | 08-APR | 30 | -5 | 25 |
11-APR | 30 | 30 | ||

You can choose to implement a simulation set in Oracle Work in Process. The work in process scheduling process considers the capacity modifications contained in the implemented simulation set when generating detailed shop floor schedules.
Attention: This method is suggested for short-term capacity changes only. If you want to make a permanent capacity change, you should update your department, resource, and shift information in Oracle Bills of Material.
