Factors Affecting Scheduling with PeopleSoft Supply Planning

PeopleSoft Supply Planning considers several factors when determining the actual start and due date and time of production, teardown, or rework orders, as well as the actual start date and time and actual due date and time of each operation. These factors include:

  • Planning constraints.

  • Material availability.

  • Planning labor or machine setup, run, and fixed run times or run rates defined for each operation.

  • Operation overlap.

  • Operation intensity.

  • Work center calendars, if they exist for the work centers associated with each operation.

  • The production calendar, if one exists.

  • The five-day workweek calendar.

Note: Although you can maintain calendars in PeopleSoft Supply Planning, you must use the calendars maintained in PeopleSoft Manufacturing. The calendar data is sent to PeopleSoft Supply Planning with other production data when you are creating a PeopleSoft Supply Planning schedule.

You define these factors as you set up manufacturing data for each business unit, item, work center, or routing. You can also define these factors when maintaining the operation list if the production is in Firmed or Released status.

As PeopleSoft Supply Planning generates an optimized production plan, the system considers material and resource requirements across all production. Additionally, if an item's primary routing causes a constraint violation, the system considers an alternate routing. When the routing is selected, PeopleSoft Supply Planning schedules individual operations for new or existing production, again considering all constraints. The system then sends this information (in the form of planning messages) to PeopleSoft Manufacturing. These messages recommend that new production IDs or production schedules be added or existing production IDs and production schedules be rescheduled or canceled.
