add_relation
Add a relation between two activities and reschedule the project.
A precedence relation between two activities ID1 and ID2 is characterized by:
-
Lag type: the type of the relation can be one of the following types
- Start-Start (SS) relation: activity ID2 can only start after the start of activity ID1
- Start-Finish (SF) relation: activity ID2 can only finish after the start of activity ID1
- Finish-Start (FS) relation: activity ID2 can only start after the finish of activity ID1
- Finish-Finish (FF) relation: activity ID2 can only finish after the finish of activity ID1
- Lag value: the time-lag between two activities can be positive, zero or negative.
Rescheduling the project can lead to conflicts due to activity constraints. This function returns 0/1 if the reschedule was a failure/successful. The rescheduling function can be put off by the P2Schedule:put_batch_calculator_on function.
