R EMARKS
If an operator is selected for an activity from an operator set, the skill factor of that opera-
tor as defined in the Operator Group module will be used for that operator for that activity.
A common use of Operator Groups is to form a group of people who can perform certain
tasks. For example, you might have an Electricians group and a Mechanics group. Some
tasks might require just an Electrician, some tasks might require just a Mechanic, and
some tasks might require multiple Electricians and Mechanics.
Another common use is to create groups of primary and alternate people. For example,
you might form a group called Repairmen that consists of Journeyman, Apprentice, and
Supervisor (in that order). Then when you specify that an activity needs someone from the
Repairmen group, you can specify Preferred Order for the selection rule. This will select
Journeyman (if available); otherwise, Apprentice (if available); otherwise, Supervisor. If
none are available, it will wait for the first of the three that becomes available.
Operator Schedule module
D
ESCRIPTION
The Operator Schedule module defines schedules to which operators (individual or
groups) can be assigned. The schedule is based on the planning horizon structure, with an
operator availability state associated with each timeslot. A timeslot is the smallest time
period that can be scheduled (e.g., 15 min., 30 min., or 1 hour).
The defined availability states include On-Duty, Lunch, and Break. If a shift does not
define one of these states for any period of time, the operator is presumed to be Off-Duty.
R EMARKS
By default, all timeslots are initialized to an Off-Duty availability state. Therefore,
operator shifts need only be defined for those time intervals that are not Off-Duty.
The starting and ending times for shifts must coincide with the starting and ending times
of timeslots within the planning horizon.
Overlapping operator shift intervals are not allowed. For example, a shift from 8:00 AM to
3:00 PM and a shift from 2:00 PM to 5:00 PM on the same day is invalid.
Shifts are defined for each calendar day. Therefore, a shift that spans two days must be
defined in two separate segments (e.g., Monday: 8:00
PM – midnight; Tuesday: midnight –
6:00 AM ).
An entry must be made in the Daily Schedule for each day of the week, although no shifts
need to be defined for any day. For example, if everyone is Off-Duty on the weekends, no
