Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "This dissertation presents solutions for the application of partial order methods to the verification of timed systems, with the purpose of reducing the size of the explored state space. Timed systems, which rely on timing information to operate correctly, pose special difficulties for automatic verification. Not only does the size of their state space grow exponentially with the number of components, as in any concurrent system, but some of the history of past transitions becomes part of the timed state. This hinders the use of partial order reduction, a technique which is applicable if different transition interleavings lead to the same state. We have given a partial order reduction algorithm for systems described as networks of timed automata, which preserves formulas in a timed extension of linear temporal logic. The algorithm is based on a modified local-time semantics, which allows individual automata to execute independently except for synchronization transitions. More generally, we have investigated the application of partial order reduction in a continuous-time model whose semantics is defined in terms of timed traces. We show how to separate the causal dependence of transitions from their time ordering due to concurrency and how this leads to the application of partial order reduction. As particular instances of this framework we obtain improved algorithms for timed event/level structures and time Petri nets, as well as our algorithm for timed automata. We have evaluated the performance of our partial order reduction approach on several timed automata benchmarks. The resulting reduction in state space stems from two sources: the local-time model reduces the number of generated time regions, while the partial order techniques applied from the domain of untimed systems reduce the explored control state space."

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the papers that were presented at the 8th International Conference on Formal Modeling and Analysis of Timed Systems (FORMATS 2010), held September 8–10, 2010, at IST (Institute of Science and Technology) Austria, in Klosterneuburg, Austria. The modeling andanalysis oftiming aspects of systems is a keyproblem that has been treated independently in several di?erent communities in computer science and related areas. Researchers interested in semantics, veri?cation, re- timescheduling,andperformanceanalysisstudymodelssuchastimedautomata and timed Petri nets, the digital design community focuses on propagation and switching delays, and designers of embedded controllers need to take into - count the time requiredby controllersto compute their responses after sampling the environment. Although the timing-related questions in these separate c- munities have their own speci?c nature, there is a growing awareness that there are basic problems that are common to all of them. In particular, all of these disciplines model and analyze systems whose behavior depends on combinations of logical and timing constraints between occurrences of events. The aim of FORMATS is to promote the study of fundamental and practical aspects of timed systems, and to bring together researchers from di?erent d- ciplines that share an interest in the modeling and analysis of timed systems. Typical topics include (but are not limited to): – Foundations and Semantics: theoretical foundations of timed systems and languages; comparison between di?erent models (timed automata, timed Petri nets, hybrid automata, timed process algebra,max-plus algebra, pr- abilistic models).

This book was released on 2008-11-05 with total page 881 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the conference proceedings of ISoLA 2008, the Third International Symposium on Leveraging Applications of Formal Methods, Verification and Validation, which was held in Porto Sani (Kassandra, Chalkidiki), Greece during October 13–15, 2008, sponsored by EASST and in cooperation with the IEEE Technical Committee on Complex Systems. Following the tradition of its forerunners in 2004 and 2006 in Cyprus, and the ISoLA Workshops in Greenbelt (USA) in 2005 and in Poitiers (France) in 2007, ISoLA 2008 provided a forum for developers, users, and researchers to discuss issues related to the adoption and use of rigorous tools and methods for the specification, analysis, verification, certification, construction, test, and maintenance of systems from the point of view of their different application domains. Thus, the ISoLA series of events serves the purpose of bridging the gap between designers and developers of rigorous tools, and users in engineering and in other disciplines, and to foster and exploit synergetic relationships among scientists, engineers, software developers, decision makers, and other critical thinkers in companies and organizations. In p- ticular, by providing a venue for the discussion of common problems, requirements, algorithms, methodologies, and practices, ISoLA aims at supporting researchers in their quest to improve the utility, reliability, flexibility, and efficiency of tools for building systems, and users in their search for adequate solutions to their problems.

Book excerpt: This volume contains the proceedings of the conference on Computer Aided V- i?cation (CAV 2002), held in Copenhagen, Denmark on July 27-31, 2002. CAV 2002 was the 14th in a series of conferences dedicated to the advancement of the theory and practice of computer-assisted formal analysis methods for software and hardware systems. The conference covers the spectrum from theoretical - sults to concrete applications, with an emphasis on practical veri?cation tools, including algorithms and techniques needed for their implementation. The c- ference has traditionally drawn contributions from researchers as well as prac- tioners in both academia and industry. This year we received 94 regular paper submissions out of which 35 were selected. Each submission received an average of 4 referee reviews. In addition, the CAV program contained 11 tool presentations selected from 16 submissions. For each tool presentation, a demo was given at the conference. The large number of tool submissions and presentations testi?es to the liveliness of the ?eld and its applied ?avor.

Download or read book Formal Methods for Components and Objects written by Bernhard K. Aichernig and published by Springer Science & Business Media. This book was released on 2011-12-12 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus in development methodologies of large and complex software systems has switched in the last two decades from functional issues to structural issues; this holds for both the object-oriented and the more recent component-based software engineering paradigms. Formal methods have been applied successfully to the verification of medium-sized programs in protocol and hardware design for quite a long time. However, their application to the development of large systems requires more emphasis on specification, modeling and validation techniques supporting the concepts of reusability and modifiability, and their implementation in new extensions of existing programming languages like Java. This state-of-the-art survey presents the outcome of the 9th Symposium on Formal Methods for Components and Objects, held in Graz, Austria, in November/December 2010. The volume contains 20 revised contributions submitted after the symposium by speakers from each of the following European IST projects: the FP7-IST project AVANTSSAR on automated validation of trust and security of service-oriented architectures; the FP7-IST project DEPLOY on industrial deployment of advanced system engineering methods for high productivity and dependability; the ESF-COST Action IC0701 on formal verification of object-oriented software; the FP7-IST project HATS on highly adaptable and trustworthy software using formal models; the FP7-SST project INESS on an integrated European railway signalling system; the FP7-IST project MADES on a model-driven approach to improve the current practice in the development of embedded systems; the FP7-IST project MOGENTES on model-based generation of tests for dependable embedded systems; as well as the FP7-IST project MULTIFORM on integrated multi-formalism tool support for the design of networked embedded control systems.
