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 following scheduling 
 rule choices are available :
 
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) are to 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) are to 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) are to 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) are to 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) are to 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) are to be sorted in the order of increasing 
 values of their 
durations.
