Scheduling Rules
The primary scheduling rule is used to order the list of activities whose
predecessor activities have been completed while
scheduling activities subject to resource constraints. The secondary scheduling
rule is used to break ties caused by the primary scheduling rule. The scheduling
rule choices are
The default primary scheduling rule is Late Start Time, while the default secondary
scheduling rule is Shortest Duration.
The Activity Priority scheduling rule specifies that activities in the
waiting list (for resources) should be sorted in the order of increasing
values of their priority.
The Delayed Late Start scheduling rule specifies that activities in the
waiting list (for resources) should be sorted in the order of increasing
values of their late start plus their
delay.
The Late Start Time scheduling rule specifies that activities in the
waiting list (for resources) should be sorted in the order of increasing
values of their late start.
The Late Finish Time scheduling rule specifies that activities in the
waiting list (for resources) should be sorted in the order of increasing
values of their late finish.
The Resource Priority scheduling rule specifies that activities in the
waiting list (for resources) should be sorted in the order of increasing
values of the resource priority for the most
important resource used by each activity. In other words, the resource
priorities are used to assign priorities to the activities in the project;
these activity priorities are then used to order the activities in the waiting
list (in increasing order).
The Shortest Duration scheduling rule specifies that activities in the
waiting list (for resources) should be sorted in the order of increasing
values of their durations.
