Definition

The rates or takt times define the parameters for the takt-based scheduling of planned orders. You can enter this master data in Line design .

Line design differentiates between the three following rates and takt times, with which you can plan your production. Therefore, the takt time is the reciprocal of the rate entered.

With this takt time you can define the maximum capacity of the production line on a long-term basis. The minimum takt time is the time in which a material is retained for processing in a takt (processing station) of the production line. Therefore, if you give a material in the production line a time interval of the minimum takt time, then in this time interval one material will be completed. The production line produces the maximum rate and the maximum production quantity.

This takt time gives the time interval in which a material joins the production line and a processed material leaves the production line. It therefore determines the time that passes between the completion of two units of measure of a product on the production line. With the planned rate you can plan the production rate for a period for the short to medium term. You can enter the planned rate manually or set it in a line balance.

The operative production rate overwrites the planned rate. With this rate you can react to any short term changes in requirements or supply. For example, if an employee takes sick leave at short notice, you can reduce the takt time for a shift. You can change the operative production rate/takt time from the sequence schedule or from the planning table .

The material-dependent rate overwrites the planned rate for a specific material. You can enter Material-Dependent Rates in a line hierarchy without a line balance. You enter the material-dependent rate in relation to the time-independent maximum rate of the production line and the system stores this rate as a factor. With scheduling, this factor is multiplied by the time-independent planned rate. If you have created a line hierarchy with line balancing, you can enter the material-dependent rates using the model-mix in the line balance.

Use

Using the rates and takt times you can plan the production quantities of a production line for both the long term as well as the medium and short term. If you simply enter a maximum rate, the minimum, planned and operative rates are all identical. By manually entering the planned rates or by using line balancing, you can change the production quantities for a period. If your planning changes at short notice, you can enter an additional operative production rate.

With rate-based production you can enter all three rates in the line hierarchy. With takt-based production you determine the planned rate using the model mix in the line balance.

Integration

Sequencing takes the rates and takt times into consideration in both takt-based and rate-based production.
