Using UML 2 activity diagram for visual business management modeling

Business process for service provisioning in public telecommunication network is very complex and demanded process. To support this process systems for business support has to satisfy all what is needed for optimal network configuration and optimal use of resources needed for service provisioning. It is very hard to achieve those assumptions without business management modelling. Model has to give a clear picture of business management and has to be a good base for implementation of needed business support for service provisioning. In this paper usage of UML (Unified Modelling Language) are chosen like example of business management modelling of the public telecommunication network. Using more diagrams UML is the tool which enables different views of system or business process which is modelled. UML activity diagram gives dynamic behaviour and could be used for modelling of business management. Finally, to enable simulation of business management formalization of UML activity diagram was used.
