This activity is used to sequence shop order operations using the Advanced Planning Board, Scheduling Client or Simulation Client window. You can choose to sequence the operations using different characteristics such as color, length, temperature and so on, connected to the part being manufactured. A given part can have more than one characteristic as well as sequencing can be based on more than one characteristic as well.
To perform this activity, the characteristics that you want to use in the sequencing process must be defined in the Inventory Part/Characteristics tab.
As a result of this activity, the operations subjected to sequence will be rescheduled to take the desired sequence once the sequencing process is completed. If sequencing is performed in the Advanced Planning Board or Scheduling Client window, the new schedule of the operations that were sequenced can be saved back to the database. In the Simulation Client window, planner can simulate sequencing and then the actual sequencing can be performed by using Scheduling Client window and save it back to the database. The last settings that is used to sequence, will be saved back to the registry and will be auto filled in the sequencing assistant when it is used on the same work center resource next time.

- Based on Characteristics Values
- Based on Least Amount of Accumulated Operation Setup time
If the first option is selected, characteristic sort order table is visible and planner can choose characteristics by using the list button based on one or more characteristics upon their importance when sequencing. The most important characteristic should have the sort order value equals to 1 and sequencing direction set to either ascending or descending. Note: To remove a characteristic from the list, select the row and press Delete.
If the second option is selected, characteristic sort order table is not visible and sequencing is not based on characteristics. Sequencing logic tries to minimize the total accumulated operation setup time when creating the sequence based on the setup matrix.
- Auto Detect Sequence Start Condition: Not available when sequencing is based on characteristic values. If this check box is selected, sequencing assistant will look at the last operation scheduled before the planned sequence start time on this work center resource and will check what is the operation that is in the set of operations selected to be sequenced with which causes least schedule set up time. Set up time defined in the set up matrix or if it is not defined, operation set up time is the set up time value taken here as the schedule set up time. Once the logic found next operation which is the most suitable with the least setup time, then it will find the next operation that causes least setup with the newly sequenced one and so on. This way the logic tries to minimize the total scheduled set up time if this option is selected.
- Include Released Operations in Sequencing Action: If this is selected, it will include release operations for sequence.
- Reassign Tool Instancies: If this is selected, when sequencing the operations can be reassigned to other tool instances to achieve the desired schedule.
- Reassign Employees: If this is selected when sequencing, the operations can be reassigned to other employees to achieve the desired schedule.
- Utilize Capacity Gaps (might alter desired sequence): If this is selected, sequencing logic will use resource availability gaps and that might alter the desired sequence. But total time span for all operations could be reduced.
