In paper the methods of model transformations created by means of visual modeling languages is considered. The detailed analysis has allowed to reveal existing problems in this area and to formulate approaches to their elimination.
It is difficult to imagine an enterprise, company, firm, an education organizations or organizations of health which does not deal with information systems. The openness and flexibility of the information systems provide a flexible and effective management. So it is necessary to adapt information system to new conditions being changed and to team up with other systems, with simulation system, for example. So it is possible change business processes, to execute their reengineering and to anticipate the conse-quences of any event and to take into account the different risks.
The approach to information system development with domain specific languages is described. DSL-toolkit allows extending business process description languages by risks description tools.
Tools of the DSM-platform MetaLanguage for creation of domain specific languages and for multilevel modeling are described. The transformations definition facility provides lower labor consumption for languages development and for model transformations.
