Oris is a tool for qualitative verification and quantitative evaluation of reactive timed systems,
which supports modeling and analysis of various classes of timed extensions of Petri Nets …

In this paper, we define Time Petri Nets with Inhibitor Hyperarcs (IHTPN) as an extension of
T-time Petri nets where time is associated with transitions. In this model, we consider …

A Web Service is a self-describing, self-contained modular application that can be
published, located, and invoked over a network, eg the Internet. Web Services composition …

Hierarchical Scheduling (HS) techniques achieve resource partitioning among a set of real-
time applications, providing reduction of complexity, confinement of failure modes, and …

Safety-critical systems are often designed as real-time distributed systems. Despite the need
for strong guarantees of safety and reliability in these systems, applying formal verification …

In this paper, we propose a method for the verification of timed properties for real-time
systems featuring a preemptive scheduling policy: the system, modeled as a scheduling time …

Time Petri nets describe the state of a timed system through a marking and a set of clocks. If
clocks take values in a dense domain, state space analysis must rely on equivalence …

Abstract The Clock Constraint Specification Language (ccsl) is a formalism for specifying
logical-time constraints on events for the design of real-time embedded systems. A central …

The Clock Constraint Specification Language (CCSL) is a formal polychronous language
based on the notion of logical clock. It defines a set of kernel constraints that can represent …

This paper presents an approach for schedulability analysis of Distributed Integrated
Modular Avionics (DIMA) systems that consist of spatially distributed ARINC-653 multicore …
