Currently, Business Process Modeling (BPM) is used to create current analytical model (As-Is model) of the work processes, upon which an optimized model (the To-Be model) can be based, including the optimization of system configuration. Also, there is strong interest in the eXecutableUML (xUML), which makes it possible to validate system viability before it is implemented. This paper proposes a methodology for configuring information systems that links BPM and xUML techniques, and evaluates its applicability. In the proposed method, bottlenecks are analyzed and evaluated using simulation of the work process flow in BPM and, after translating this model into UML model elements, and after the UML model has been created, expands it to xUML. Then, in xUML modeling, dynamic system evaluation is carried out with automatic generation of the code for actual implementation. The proposed method was applied to the development of an actual prototype information system and evaluated.
