This dialog is used to define a Capacity Interval.
- Id: A unique integer identifier for the Capacity Interval. This value is generated automatically and cannot be changed.
- Name:A unique text name to identify the Capacity Interval, such as "Shift 1Asm".This is also used to label the Capacity Interval on the Gantt.
- Description:Text that can be used to describe the purpose of the Capacity Interval such as"First shift in the assembly department".
Specifies the purpose of the Capacity Interval. This determines the impact of the Capacity Interval on the schedule.
- Normal Online: Specifies that the Resource is available to perform work and that this is a "normal" shift.
- Overtime: Specifies that the Resource is available to perform work and that this is a special "overtime" shift.
- Potential Overtime: Has no effect on the Resource's capacity. This is only a visual clue to the scheduler that overtime can be used here if needed.
- Offline: Specifies that the Resource is not available to perform work. This overrides all other Event Types.
If Capacity Intervals overlap on the same Resource then the following rules are applied:
- Offline Intervals override all other types. So any time period within an Offline Interval is always considered Offline.
- Overlapping Normal Online and Overtime Intervals have their Capacity Multipliers ADDED during the overlap period. So, for example, if two such intervals overlap and one has Capacity Multiplier=1 and the other has Capacity Multiplier=2 then the span where they overlap would be considered to have a Capacity Multiplier of 1+2=3.

- Start: The beginning of the Capacity Interval's span. This also serves as the beginning of the recurrence for Recurring Capacity Intervals.
- End: The end of the Capacity Intervals span.
- Duration: The amount of time between the Capacity Interval's Start and End. For display only.
- Capacity Multiplier: This can be used to scale the amount of capacity that a Resource has over an interval. Specifying a value of 1 means that the amount of capacity is exactly equal to the Duration, so, for example, if the Duration is 8 hours then then 8 hours of work can be done during the interval. If, however, a value of 3 were used then the same 8 hour interval would be treated as having 8 x 3 = 24 hours of capacity. One example of when this is useful is when a Resource represents a work area that has various staffing levels. A Capacity Multiplier of 1 could mean that one person is working there. A value of 5 would mean that 5 people are working there and therefore five times more work can be done in the same period of time. The smallest allowable value is 0.001.
Unless this value is set to "None", the Capacity Interval will be treated as "recurring". This means that multiple instances of it are created at the specified frequency. Note that the Duration of the Capacity Interval can limit which Recurrence options are available. For example, if the Duration is more than 24 hours then it is not possible to have a Daily Recurrence.
This determines how long the Capacity Intervals are applied to the schedule.
- End of Planning Horizon: Capacity Intervals are added until the next one would start after the Planning Horizon. This option might be used when creating standard shift patterns that will be used indefinitely.
- End After __ occurrences: Capacity Intervals are added until the specified number of them have been created. This option might be used for adding, for example, weekend overtime for the next 4 weeks.
- End by: Capacity Intervals are added until the next one would start after the specified date/time. This option might be used when a standard shift pattern will be changing at a known future date. The current shift pattern would end by that date and the new one would start at that date, thus creating a transition between the two.
