Abstract:

A modelagem de sistemas que apresentam subsistemas idênticos, por intermédio de Redes de Petri, conduz à geração de grafos de grandes dimensões com diversos componentes indênticos. As extensões às Redes de Petri que permitem diferenciar estes diversos subsistemas, por intermédio da distinção das fichas nelas contidas, receberam o nome de Redes de Petri Coloridas. Neste trabalho, são apresentados algumas propostas existentes na literatura sobre Redes de Petri Coloridas, bem como é desenvolvido um programa de análise baseado em uma dessas propostas - a de kurt Jensen.

Abstract:

With the increased scale of distributed computations the complexity of liveness proofs have increased. In this paper we endeavor to simplify the process of verifying a concurrent system using well know modeling techniques. The choice of modeling tool as well as the proof is based on future scalability and automation. We translate the formal proof to a petri-net representation and use this to verify basic algorithms. We show that the formal proof of liveness stated by Owiki and Lamport can be adapted to petri-nets. We also show a modification to petri-nets for increased granularity in loop mode

Abstract:

Context. Name-bounded analysis is a type of static analysis that allows us to take a concurrent program, abstract away from it, and check for some interesting properties, such as deadlock-freedom, or watching the propagation of variables across different components or layers of the system. Objectives. In this study we investigate the difficulties of giving a representation of computer programs in a name-bounded variation of π-calculus. Methods. A preliminary literature review is conducted to assess the presence (or lack thereof) of other successful translations from real-world programming lang

Abstract:

This thesis provides a powerful general-purpose proof technique for the verification of systems, whether finite or infinite. It extends the idea of finite local model-checking, which was introduced by Stirling and Walker: rather than traversing the entire state space of a model, as is done for model-checking in the sense of Emerson, Clarke et al. (checking whether a (finite) model satisfies a formula), local model-checking asks whether a particular state satisfies a formula, and only explores the nearby states far enough to answer that question. The technique used was a tableau method, constru

Abstract:

This work is focusing on automatic verification of systems with parallel running processes. We discuss the existing methods and certain possibilities of optimizing them. Existing techniques are essentially based on finding an inductive invariant (for instance using a variant of counterexample-guided abstract refinement (CEGAR)). The effectiveness of these methods depends on the size of the invariant. In this thesis, we explored the possibility of improving the methods by focusing on finding invariants of minimal size. We implemented a tool that facilitates exploring the space of invariants of

Abstract:

In the formal verification of software systems, model-checking is one of the most studied and applied techniques. Systems represented by mathematical models are checked against properties expressed as logical formulae. When the subjects of the verification are concurrent and distributed systems, models and specification logics capable of faithfully capturing the concurrent features of computations, like causal dependency and independence between actions of the systems, can sometimes be convenient or even essential. In this thesis we study the foundations of the model-checking problem in a log
