Scheduling Untie Sort Rules#

The Untie Sort Rules are used to break ties during the sequencing of jobs when, according to the Optimization Criteria, two or more jobs are tied (there is no preference in scheduling one before the other). In these situation, the system turns to Untie Sort Rules, applying them in the order they are filled in the system to determine the sequencing of the tied jobs. The available Untie Sort Rules are:

  • Possible Start Date - Material (Real or Virtual) Possible Start Date
  • Priority - Material (Real or Virtual) Priority
  • Execution Time - Material (Real or Virtual) Total Execution Time
  • Material Name - Material (Real or Virtual) Name
  • Quantity - Material (Real or Virtual) Quantity
  • Setup Time - Job Setup Time
  • Wait Time - Wait Time Regarding Previous Operation
  • Material Due Date - Material (Real or Virtual) Due Date
  • Operational Due Date - Component (Material Dependency) Estimated Due Date

It is possible, for each of these rules, to specify which direction, ascending or descending, is to be given priority, as can be seen in the next picture.
