Abstract :
The paper presents the approach to modeling and simulation of information systems. The systems are being analyzed from the point of services realized by them. Therefore, the system is modeled as a network of interacting tasks and technical infrastructure required for the service realization. Paper, presents the formal model of a system, accompanied with model of a task realization. Moreover, a description of developed simulator, a case study with exemplar results and simulator performance analysis is given.
