Formal specification and verification of real-time systems using Graph Grammars

Specification of Real-Time Systems with Graph Grammars

This paper presents a formal approach to specify and analyze realtime systems. We extend Object-Based Graph Grammars, a description technique suitable for the specification of asynchronous distributed systems, to be able to explicitly model time constraints. The semantics of the systems is defined in terms of Timed Automata, allowing the automatic verification of properties. Resumo. Este artigo...

Web Service Choreography Verification Using Z Formal Specification

Web Service Choreography Description Language (WS-CDL) describes and orchestrates the services interactions among multiple participants. WS-CDL verification is essential since the interactions would lead to mismatches. Existing works verify the messages ordering, the flow of messages, and the expected results from collaborations. In this paper, we present a Z specification of WS-CDL. Besides ve...

Real-time systems - formal specification and automatic verification

Specification and verification of real-time systems using ACSR-VP

The reliability of the design of a real-time system is important. For example, when there are errors in avionics control systems or nuclear reactor control systems, the loss of finance, time or even the loss of human lives could be enormous. Therefore when one designs a real-time system, methods to guarantee the correctness of the system are needed before the implementation of the system. We sp...

Real-time systems - specification, verification and analysis

Bargaining with reading habit is no need. Reading is not kind of something sold that you can take or not. It is a thing that will change your life to life better. It is the thing that will give you many things around the world and this universe, in the real world and here after. As what will be given by this real time systems specification verification and analysis, how can you bargain with the...
