Scheduling Setup: Periods

To access this screen:

Display the Optimization task bar and select Optimization >> Scheduler >> Maroma >> Settings >> Periods.

Define sequential periods for the Maroma scheduler.

This determines the resolution of your schedule as a linear progression of either:

Quarterly or yearly periods (or both, starting with quarters and ending with years in the more distant future).
Yearly or multi-year periods (or one followed by the other) for a less granular period calendar.

Note: Scheduling calendar periods can only increase in size, not decrease, into the future. For example, a calendar where 12 quarters is followed by 4 yearly periods is fine, but you can't start with yearly periods and reduce to quarters later.

To define scheduling periods using Maroma:

Warning: Changing a scheduler calendar can affect (and invalidate) other settings.

Select the starting Quarter and Year of the initial period. For example, Qtr 1, 2025.
Use Create Periods controls to define the first batch of periods (where a 'batch' relates to contiguous periods of the same length):

Note: A schedule duration must be at least one year = 4 quarters.
- To include only quarterly periods in your schedule—Select of one quarter and select the number of quarters from 4 to 76.
- To include quarters and years—Select of one quarter and select the number of quarters from 4 to 76, then enter the number of one year periods to follow (any number).
- To include only years in your schedule—Select either of one quarter or of one year and set it to zero, then enter the number of one year periods.
- To include years and multi year periods—Select the lower option and enter the number of one year periods to start, then enter the number of x years periods to follow.
  
  For example, to start the schedule with 5 yearly periods, followed by 5 more 2-year periods, choose 5 of one year and 5 of 2 years.
- To include only multi-year periods—Select the lower option and add zero of one year, then enter the number of x years periods to follow.
Click Create to regenerate the calendar on the right.

To remove the final period, click Delete last period, or Delete all periods to clear the calendar(although note that clicking Create will automatically clear previous results).
