Sequencing Assembly Orders

Start Manufacturing > Assembly Control > Simulate and Create Line Sequences (tiasl4200m000).

For more information, refer to Line sequencing and rule types in Assembly Control.

Generating a sequence of assembly orders per line station is a mandatory step in the procedure, even if you do not intend to use the sequencing engine. The assembly orders on each line must have the status Sequenced before you can continue with the process.

The sequencing process starts from the roll-off line. The sequencing engine sequences assembly lines individually, starting from the roll-off line and progressing backwards. For the supplying line, we must re-run the sequence engine .

The following are the sequencing options that are available in the Simulate and Create Line Sequences (tiasl4200m000) session:

  • Local Improvement

    If this check box is selected,, LN optimizes the sequence for the segment selected in the Pivot Segment field. You can select the Neighbor Checking check box to optimize the sequence for a segment.

  • Neighbor Checking

    If this check box is selected,, LN takes account of the segments immediately before and after the specified segments during the optimization process. This action gives rise to a sequence that is translatable to the neighbor segments, which means that the sequence changes are feasible. You can select this check box only if the Local Improvement check box is selected. If the Global Improvement check box is selected, LN automatically selects the current check box.

  • Global Improvement

    If this check box is selected,, LN optimizes the sequence for all the segments that you select in this session.

  1. Define the sequence selection criteria.

  2. Click Generate and check if error messages are logged. If required, troubleshoot the messages. If you want to first evaluate generated sequences, do not select the Confirm Sequence option but first evaluate your run. Select your run number from the Sequence Quality group box, and click Evaluate. LN displays the sequence of the assembly orders on different line segments through a report.

  3. Click Confirm to confirm the run number. LN saves the generated sequence, which you can view, per line segment, in the Line Segment - Line Sequence (tiasl4500m000) session. Verify that the generated sequence is saved.

  4. Repeat steps 2 and 3 for sequencing your supplying line.

  5. Open the Assembly Orders (tiasc2502m000) session and check if your assembly orders have the Sequenced status. Verify that the related line station orders are still in the Planned status.

  6. Open the Assembly Orders (tiasc2502m000) session and verify the following:

    • The assembly orders with the Sequenced status have a serial number.
    • LN generates an As-Built header.
