In large organizations the administration of access privileges (such as the assignment of an access right to a user in a particular role) is handled cooperatively through distribu...
When designing a complex system, Object-Z is a powerful logic-based language for modeling the system state aspects, and Timed Automata is an excellent graph-based notation for cap...
The Behavior Tree notation has been developed as a method for systematically and traceably capturing user requirements. In this paper we extend the notation with probabilistic beha...
— This paper extends the notion of residuals for fault detection, well known in the continuous system to the timed discrete events systems. The aim is to design the fault indicat...
We present a model, task automata, for real time systems with non-uniformly recurring computation tasks. It is an extended version of timed automata with asynchronous processes th...
