with rounded results may however, as a consequence of rounding, change the solution set of a cross-

impact matrix.

Fig. 5-11: Entering a factor for cim factor multiplication.

A negative factor inverts all impact relations. The resulting cross-impact matrix thereby describes a

totally different system and leads to totally different solutions.

In ensemble mode (section 6.7) all cross-impact matrices of the ensemble are multiplied by the speci-

fied factor.

Factor multiplication is useful in practical situations, for example if the user wants to refine the

judgement scale in the course of cross-impact data sampling. A factor multiplication of 2 for example

creates new space for intermediate values when judging impact strength.

The menu item Edit - Factor Multiplication is only available once a descriptor state list and a cross-

impact matrix or an ensemble have been defined.

5.12 Transpose

The menu item Edit - Transpose transposes the current cross-impact matrix. This equals an inversion

of the causal relations in the system: impact sources will be impact targets and vice versa.
