Defining Number of Takts and Capacities

Use

You use this function to define the number of takts (processing stations) and individual capacities (such as personnel or machinery) in a line segment.

Number of takts

You can define how many processing stations are in a line segment, for the purposes of takt-based scheduling. This means that you do not have to create a line segment (work center) for each processing station. The number of takts multiplied by the minimum takt time is the amount of time that a material spends in a line segment.

If you work with lead time scheduling via routing, the system does not take into account the number of takts when calculating the operation duration. If you want to represent parallel work in the system using splitting, you must therefore create a line segment (work center) for each takt.

Number of individual capacities

You can increase the capacity of a line segment by multiplying the number of individual capacities on the work center. With the amount of individual capacities, you define, for example, how many personnel or machines are used at line segment. This modified amount is only valid in the line hierarchy, since the system does not change the work center.

You can define an unlimited amount of takts and individual capacities for a production line. Since the amount must be uniform for the whole production line, you can only enter the takts and capacities in the branches of the line hierarchy (from the uppermost level downwards) on one level respectively (see also Example of Number of Takts and Individual Capacities ).

Integration

The number of takts and individual capacities should be sufficient to cope with the maximum capacity load utilization of the production line (maximum production rate). When carrying out line balancing for the line hierarchy, you can change entries to adjust the production line capacity to suit the planned production rate, in case of changes in the requirements situation. Any entries made in a version of a line balance are only valid for that version. The system does not change the entries in the line hierarchy, unless you have selected Maximum line balancing in the line balance.

In the line balance, the system displays a separate row for the line segments, for which you enter takts and capacities. These line segments are therefore relevant for line balancing. Operations from the routing can be moved between these line segments.

In the line hierarchy, you can flag the amount of takts as relevant for line balancing. Then the system displays a separate row for each takt.

The total of all the takts in the line segment equals the length of the production line that Sequencing uses for scheduling based on takts.

Prerequisites

You must work with scheduling based on takts in Sequencing or in discrete manufacturing.

Features

The system compresses the number of takts and individual capacities upwards from the level that they entered on. The amount of takts is displayed in each line segment in the line hierarchy. The total amount of takts on the production line (length of the production line) is displayed in the line hierarchy header.

You can multiply the number of individual capacities for each capacity category in the work center. The system does not copy the changes to the work center. They are only valid for the line hierarchy.

Actions

Starting from the line hierarchy graphic, select a line segment and then the menu path Edit ® Takt/capacity details.

You branch to the screen Number of takts/individual capacities.

Enter the amounts in the appropriate areas.

Choose Continue.

If you want to check the number of individual capacities per line segment in an object tree, choose the tab page Object Tree in the line hierarchy menu.
