It is based on the simple Erlang's formula equation plus qualitative knowledge about the network. This model has been built to serve as the support of a model-based supervision whose main function is to determine, in a given network, which streams are responsible for call losses in communitation organs (circuit groups and exchange centres) of the network. The idea of the algorithm is to determine streams responsible for call losses in communication organs by comparing their traffic values to nominal values. As stream traffic values are not directly available from the on-line data acquisition system, they are computed by inverting our model thanks to evolutionary algorithms.
