Examples of Production Scheduling
The following examples illustrate how PeopleSoft Manufacturing creates and maintains operation schedules. These examples illustrate how the system calculates actual start and due dates and times for different operations using forward and backward scheduling.
Note:
These examples assume that you are not using the PeopleSoft Supply Planning solvers to schedule production.
The examples use these types of shop floor operations:
-
Example 1: Operations with no overlap; queue and setup are done sequentially.
-
Example 2: Operations with no overlap; queue and setup are done concurrently; queue time is less than setup time.
-
Example 3: Operations with no overlap, queue and setup are done concurrently; setup time is less than queue time.
-
Example 4: Operations with no overlap; setup is not included.
-
Example 5: Operation overlap; queue and setup are done sequentially.
These production times are used for all examples:
| Op | Queue | Setup | Run | Intransit | Overlap |
|---|---|---|---|---|---|
|
10 |
None |
1 hour |
5 hours (.5 hr/unit) |
2 hours |
None |
|
20 |
1 hour |
3 hours |
10 hours (1 hr/unit) |
1 hour |
None |
Note:
Even though PeopleSoft Manufacturing calculates start and due dates and times to the minute, hours are used to make it easier to manually calculate these shop floor operation examples.
All examples assume a 24-hour day with an operation start quantity of 10 units. The start of the operation is when setup starts.
