Calendars

A calendar represents a numeric value that is varying over time.

Calendars can be linked to multiple entities: a maximum capacity limit of a resource, a minimum capacity usage of a resource, a minimum or maximum inventory limit of a buffer, etc…

A calendar has multiple buckets to define the values over time. See calendar buckets for more details. To determine the calendar value at a certain date the calendar will evaluate each of the buckets and combine the results in the following way:

• A bucket is only valid from its “start” date (inclusive) till its “end” date (exclusive).

  Outside of this date range a bucket is never selected.
• If multiple bucket are effective on a date, the one with the lowest “priority” value is taken.

  In case buckets have the same priority, the value of the bucket with the latest start date is selected.

• In case no bucket is effective on a certain date, the calendar will return the “default” value.
