| # Simulate and Create Line Sequences (tiasl4200m000) Use this session to generate a sequence of assembly orders for an assembly line. Related topics Assembly control overview Line sequencing and rule types in Assembly Control Line station variants and line station orders Assembly order costing Assembly backflushing Assembly line station utilization Assembly orders Sequence Options Sequence Options Select an improvement method. LN only optimizes the sequence for the segment selected in the Pivot Segment field. You can also select the Neighbor Checking check box to optimize the sequence for a segment. Local Improvement If this check box is selected, LN only optimizes the sequence for the segment selected in the Pivot Segment field. You can also select the Neighbor Checking check box to optimize the sequence for a segment. Global Improvement If this check box is selected, LN optimizes the sequence for all the segments that you select in this session. Confirm Sequence If this check box is selected, the sequence that LN generates is confirmed automatically. The orders in the sequence are offset and the planning data for ASC orders, such as segment start time and segment end time, are calculated. If this check box is cleared, you can confirm the sequence when you click the Confirm button, after you select the run number of a previously generated sequence. 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 gives rise to a sequence that is translatable to the neighbor segments, which means that the sequence changes are feasible. You can only select this check box if the Local Improvement check box is selected. If the Global Improvement check box is selected, LN automatically selects the current check box. Offsetting Options Offsetting Options Select an option for calculating the offset. Backlog If this check box is selected, LN takes a backlog into account when it calculates the offset. That means that the first order is planned at the beginning of the period you specify in this session. Actual Times If this check box is selected, and LN calculates the offset, it takes into account when the last order was reported completed on the last line station of a segment. Next time you run this session to replan a line sequence, LN takes the difference between planned end time and actual end time into account. Sequence Selection Assembly Line The assembly line that you want to sequence. Pivot Segment The segment for which you have defined parameters in the Remix/Sequence Parameters (tiasl4110m000) session and from which LN starts generating sequences. If you sequence multiple segments, LN sequences the pivot segment first. This segment is then copied to the other segments within the range, and the segments are then sequenced. If you selected the Global Improvement check box, this is the segment for which you defined parameters. You can switch to different parameters by entering a different pivot segment in this field. Note You must carefully select a segment that is representative of your assembly line. You can simulate line sequences for your assembly line with various different segments as the pivot segment, to see which gives the most efficient sequence. Line Segment A set of consecutive assembly-line work centers on an assembly line between two buffers. The first buffer is the beginning of the segment, the next buffer is the first part of the next segment. Sequence Date The actual offline date of new orders which are taken into account and added to the sequence in the sequencing process. LN always takes previously sequenced orders into account, irrespective of the date range you specify in this field. Sequence Quality Run Number The identification number of the sequencing run. To see results of other run numbers, click the Up or Down button. Penalty Cost Theoretical costs for not meeting rules on an assembly line. Convertible Indicates whether the sequence is translatable between the different segments of the assembly line. Sequence Progress Initialize Sequence The value of this field indicates whether a sequence was initialized, by adding a new assembly order, for the selection you made in this session. Initial Penalty Cost Penalty cost of the sequence before optimization has taken place. Selected Sequence The run number of the selected run. Generate Generates the sequence. Evaluate Prints a report that shows the order sequence and the order option combinations for each segment of the selected run number. Confirm Permanently stores the order sequence of the selected run number. Parameters Starts the Remix/Sequence Parameters (tiasl4110m000) session. Messages Displays error messages and warnings.
