Task Synchronization

Use

TRM synchronizes related tasks , tasks that belong to the same request or wave.

Features

If a task that has related tasks is created during the Critical Time Window (CTW), the task and its related tasks may receive a synchronization priority boost according to their Latest Starting Date (LSD) priority values.

If a task that has related tasks is selected during the CTW, its related tasks may receive a synchronization priority boost according to their LSD priority values.

Note Note

For more information on the LSD and CTW, see Latest Starting Date .

End of the note.

Example

You define the CTW for both LSD and synchronization priority purposes as beginning 60 minutes before the LSD and ending when the LSD is reached.

  • Task A1 is created from request X two minutes after the commencement of its CTW. Since it has no related tasks, it is not given a synchronization priority.

  • Task A2 (related to task is created from request X four minutes later, three minutes after the commencement of its CTW.

    • Task A1 receives a synchronization priority value of 10 since 10% (six minutes) of its CTW has elapsed.

    • Task A2 receives a synchronization priority value of 5 since 5% (three minutes) of its CTW has elapsed.

  • Task A3 is created from request X twelve minutes later, six minutes after the commencement of its CTW.

    • Both tasks A1 and A2 receive a synchronization priority value boost of 20 since a further 20% of their CTWs have elapsed.

    • Task A3 receives a synchronization priority value of 10 since 10% of its CTW has elapsed.

  • Task A1 is selected three minutes later.

    • Both tasks A2 and A3 receive a synchronization priority value boost of 5 since a further 5% of their CTWs have elapsed.

  • Task A2 is selected after another fifteen minutes.

    • Task A3 receives a synchronization priority value boost of 25 since a further 25% of its CTW has elapsed.

Thus Tasks A1, A2 and A3 receive synchronization priority values as follows:

Synchro Priorities

At task selection , these synchronization priority values are multiplied by the relevant weighting factors to influence the tasks’ static & synchronization priority model entities and, ultimately, the total priorities of the tasks.
