Sequencing relationships

Sequencing relationships describe the intended order of specified activities in the timetable. You can specify that activities must occur at the same time, or that some activities must precede others.

Sequencing relationships are scheduling constraints. When you manually schedule an activity, sequencing relationships affect which start times in the timetable area contain the blue diamonds that represent valid start times. When Enterprise Timetabler automatically schedules activities, sequencing relationships determine the set of possible start times that Enterprise Timetabler can choose from for an activity, in order to construct a scheduling solution.

If a new sequencing relationship involves a scheduled activity that breaks the relationship, a scheduling problem is generated when the relationship is saved.

The teaching week pattern of each activity is not part of the constraint, but is a relevant aspect of activity data to consider when deciding how to achieve your scheduling goal. For example, in the following scenarios, a same time relationship and teaching week pattern combine to achieve different outcomes:

  • If the activities have the same teaching week pattern, the same time relationship ensures that the activities occur simultaneously.
  • If the activities have different teaching week patterns, the activities have the same scheduled day and time in different weeks. For example, to provide timetable continuity for students, a same time relationship can ensure that a lecture that occurs only within weeks 1-6 is scheduled at the same time as a different lecture that occurs within weeks 7-12.
