Abstract: Method and arrangement for matching of enterprises and detection of changes for an enterprise by the use of mathematical models that make it possible to match and find similarities between enterprises and also discover changes in an enterprise. The method uses mathematical representation models for enterprises and is suited to make a large number of comparisons automatically. The characteristics of the enterprises are represented by different vectors. The direction and length of the vectors are compared by taking the scalar product between them. Changes for the characteristics of an enterprise appear as changes in the direction and length of the vectors. By continuously monitoring the derivative of the characteristics of the enterprises this show how large and how quickly a change has occurred.
