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. 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:
In case no bucket is effective on a certain date, the calendar will return the “default” value.
|name||non-empty string||Unique name of the calendar. This is the key field and a required attribute.|
|default||double||The default value of the calendar when no bucket is effective.|
|value||double||The actual time-varying value.|
Start date of the validity of this bucket.
When left unspecified, the entry is effective from the infinite past.
Makes up the key together with the end and priority fields.
End date of the validity of this bucket.
When left unspecified, the entry is effective indefinitely in the future.
Makes up the key together with the start and priority fields.
Priority of this bucket when multiple buckets are effective for the same date.
Lower values indicate higher priority.
Makes up the key together with the start and end fields.
|days||integer between 0 and 127||
Bit pattern representing the days on which the calendar bucket is valid:
Bit 0 = 1 = Sunday
Bit 1 = 2 = Monday
Bit 2 = 4 = Tuesday
Bit 3 = 8 = Wednesday
Bit 4 = 16 = Thursday
Bit 5 = 32 = Friday
Bit 6 = 64 = Saturday
The default value is 127, ie valid on every day of the week.
Time when this entry becomes effective on valid days in the valid date horizon.
The default value is PT0S, ie midnight.
Time when this entry becomes ineffective on valid days in the valid date horizon.
The default value is PT23H59M59S, ie right before midnight of the next day.
