An approach to formal modeling and analyzing of organization decision information systems

An approach to modeling and analyzing of the behavior of information systems by means of Petri nets is presented. The method provides a formal model which can, simply and explicitly, represent the concurrent, cyclic, asynchronously coordinated, alternative activities taking place within a complex organizational information system. It is also able to represent quantitative (temporal) information and to give the results of the system performance in terms of time. A simple ticket reservation procedure is examined to demonstrate the suitability and ease use of the method
