Calendar schedule information
Time Pattern
D ESCRIPTION
A Time Pattern defines a series of values that change over time. For example, a worker
might be on duty during a standard work shift from Monday through Friday. The avail-
ability of the worker could be represented as a value of 1 when he’s on duty, 0 when he’s
off duty. The time pattern that defines this availability schedule would list the changes
from on duty to off duty over the week.
Time patterns are saved in an Arena model in the Schedule module with a Type set to
Calendar. Their data are edited via the Time Pattern window, which is opened from the
Edit > Calendar Schedules > Time Patterns menu option.
