Assembly line station utilization

The utilization of an assembly line is the ratio of the actual number of orders for that line divided by the maximum number of orders for that line. You can display the utilization in the Assembly Line - Line Utilization (tiasl3500m000) session. If you have changed your order data, you must run the Rebuild Line Utilization (tiasl3200m000) session before you can see the utilization.

You can read further details about the number of orders planned for a line in the Assembly orders online manual topic.

The maximum number of orders for a line (for an option combination) is determined by:

• The line mix rules (see the Line sequencing and rule types in Assembly Control online manual topic).
• The assembly assignment of a line.

The assembly assignment is made up of the following factors:

• The cycle time for each period (non-average) or for the whole day (average).
• Man and machine resources for each line station.
• The time that the line station requires to process one assembly order. This time is expressed as a number of cycles. For instance, if the cycle time is two minutes, ten minutes is expressed as five cycles.

You define assembly assignments in the Assembly Line - Assignments (tiasc5510m000) session and link them to a particular line station in the Assembly Line - Assignments and Line Stations (tiasc5520m000) session.

When you have manually rescheduled orders, the utilization of the assembly line is altered.

You can use the Utilization by Critical Option Combination (tiasl3510m000) session to view the number of planned orders and the maximum number of orders on an assembly line for a given date, for option combinations that are used for line mix rules (that is, critical option combinations). You can also view this data as a graph with the Assembly Line - Line Utilization - Chart (tiasl3700m000) session.
