Repetitive Schedules as Planned Supply

Repetitive planning always acts on completion dates. Notice that repetitive schedules have two completion dates: first unit completion date and last unit completion date. These two completion dates are analogous to due dates for planned orders. In both cases, the dates represent the date when supply is assumed to be available to satisfy demand. The repetitive planning process always assumes that the supply is available at the beginning of the day.

The planned supply represented by repetitive schedules becomes available to satisfy demand after the first assembly on the schedule is completed. Thereafter, there is supply, for a quantity equal to the daily rate, for each workday between the FUCD and the LUCD.

To ensure that the supply is available on the first date on which demand needs to be satisfied, the repetitive planning process offsets the FUCD by the assembly lead time to determine the FUSD. The following diagram illustrates this relationship.

The repetitive planning process always assumes that production can only take place on a workday.
