In this step you define the setup matrix.

In the setup matrix you store values and units for the setup standard values of operations depending on the setup state of the work center.

Various dispatching functions on the capacity planning table for capacity leveling (for example, setup time optimization) take into account that the setup time for an operation depends on which operation was previously processed at the work center, that is in what setup state the work center is. These functions do not use the value for the setup standard value from the operation but instead the value from the setup matrix.

Note

The setup matrix for PP-PI is therefore not relevant.

The setup state of a work center is characterized in the setup matrix by the setup group category and the setup group key that are saved in the operation to be processed.

A transition between two setup states is identified by the setup group categories and the setup group keys of two operations that are processed at the work center one after the other. The value for the setup standard value that you store in a transition is assigned to the successor operation.

You can specify for every individual setup transition which standard value is regarded as the setup standard value in the following operation. If a setup transition is not maintained in the setup matrix then you should specify in the control profile which standard value is to be interpreted as the setup standard value.

The standard value "1" is predefined internally both in the control profile and for a setup transition in the setup matrix.

You define a transition in the setup matrix as follows

Enter for the

Predecessor group	the setup group category of predecessor
Predecessor subgroup	the setup group key of predecessor
Successor group	the setup group category of successor
Successor subgroup	the setup group key of successor

In the setup matrix you can also define whether a transition is permitted or forbidden. For example, this is taken into account in setup time optimization when forming a sequence of operations where the setup time is minimized.

You can use the wildcard character * for the setup group key in the setup matrix as described in the following example: For example, the system searches in the setup matrix for an entry with the setup group key ABC for the predecessor. If it does not find a key ABC it looks for the key AB*, then for a key A* etc until it finds one of them.

Initial setup states

The setup state of the work center is not defined for the case where an operation does not have a predecessor in the evaluation period. You can define the setup state of the work center by entering an initial setup state in the strategy profile. To calculate the setup time of this first operation at the work center the system can use the setup standard value that is assigned in the setup matrix to the transition between the initial setup state and the setup state for processing the operation. An initial setup state can only occur in the setup matrix as a predecessor for a transition. You can only use a key that is a maximum of three characters long for the predecessor group for the initial setup state. You cannot make any entry for the predecessor subgroup.

Successor subgroup

Define the setup matrix.

Successor subgroup

The setup group key and the setup group category are not checked in the setup matrix.
