Example: Number of Takts and Capacities

This example shows a line hierarchy with two segments beneath the header of the line hierarchy (two branches).

In the first branch there are two hierarchy levels. The number of takts and the number of individual capacities are given on the lowest level. The system displays the summarized number in the uppermost level. The first branch then, has four takts and five individual capacities. The individual capacities can, for example, be people or machines.

The second branch consists of one hierarchy level only and therefore of one line segment only. For this line segment there are two takts and two individual capacities.

The total number of takts and the overall length of the production line is, therefore, six takts. In this example the takts are connected by a conveyor system. A material passes through each of these takts and remains there for the minimum takt time of ten minutes.

The system distributes the individual capacities available in a line segment equally over the number of takts. In segment_3, for example, there are three people working on two takts. Therefore, two people at a time can work on one takt for the minimum takt time of ten minutes. The third person can work on both takts, each for five minutes.

On the pre-condition that both takts in segment_3 have been defined as relevant to line balancing, the system reproduces segment_3 in the capacity view of the line balancing in the following way:

The line balancing graphic displays a separate segment for each takt. Since the model mix contains the line balance of two materials, the graphic displays one row per material in each takt. The white area of a row shows the time available in the row. The time available for both takts is 30 minutes. This can be calculated from the following formula:

Time available = Minimum takt time * Number of individual capacities

This time is distributed across two takts. Therefore each takt can be used for 15 minutes, although the material only remains in each takt for 10 minutes.
