Formal Methods For Embedded Distributed Systems

The development of any Software (Industrial) Intensive System, e.g. critical embedded software, requires both different notations, and a strong devel- ment process. Different notations are mandatory because different aspects of the Software System have to be tackled. A strong development process is mandatory as well because without a strong organization we cannot warrantee the system will meet its requirements. Unfortunately, much more is needed! The different notations that can be used must all possess at least one property: formality. The development process must also have important properties: a exha- tive coverage of the development phases, and a set of well integrated support tools. In Computer Science it is now widely accepted that only formal notations can guarantee a perfect de?ned meaning. This becomes a more and more important issue since software systems tend to be distributed in large systems (for instance in safe public transportation systems), and in small ones (for instance numerous processors in luxury cars). Distribution increases the complexity of embedded software while safety criteria get harder to be met. On the other hand, during the past decade Software Engineering techniques have been improved a lot, and are now currently used to conduct systematic and rigorous development of large software systems. UML has become the de facto standard notation for documenting Software Engineering projects. UML is supported by many CASE tools that offer graphical means for the UML notation.

Object-based Distributed Computing is being established as the most pertinent basis for the support of large, heterogeneous computing and telecommunications systems. The advent of Open Object-based Distributed Systems (OODS) brings new challenges and opportunities for the use and development of formal methods. Formal Methods for Open Object-based Distributed Systems presents the latest research in several related fields, and the exchange of ideas and experiences in a number of topics including: formal models for object-based distributed computing; semantics of object-based distributed systems and programming languages; formal techniques in object-based and object oriented specification, analysis and design; refinement and transformation of specifications; multiple viewpoint modeling and consistency between different models; formal techniques in distributed systems verification and testing; types, service types and subtyping; specification, verification and testing of quality of service constraints and formal methods and the object life cycle. It contains the selected proceedings of the International Workshop on Formal Methods for Open Object-based Distributed Systems, sponsored by the International Federation for Information Processing, and based in Paris, France, in March 1996.

This book constitutes the refereed proceedings of the 15th IFIP WG 6.1 International Conference on Formal Methods for Open Object-Based Distributed Systems, FMOODS 2013, and the 33rd IFIP WG 6.1 International Conference on Formal Techniques for Networked and Distributed Systems, FORTE 2013, held in Florence, Italy, in June 2013, as part of the 8th International Federated Conference on Distributed Computing Techniques, DisCoTec 2013. The 20 revised full papers presented were carefully reviewed and selected from 39 submissions. The papers present a wide range of topics combining theory and practice. They cover distributed computing models and formal specification, testing, and verification methods as well as application domains such as application-level distributed systems, telecommunication services, Internet, embedded and real-time systems, and networking and communication security and reliability.

The three-volume set LNCS 12476 - 12478 constitutes the refereed proceedings of the 9th International Symposium on Leveraging Applications of Formal Methods, ISoLA 2020, which was planned to take place during October 20–30, 2020, on Rhodes, Greece. The event itself was postponed to 2021 due to the COVID-19 pandemic. The papers presented were carefully reviewed and selected for inclusion in the proceedings. Each volume focusses on an individual topic with topical section headings within the volume: Part I, Verification Principles: Modularity and (De-)Composition in Verification; X-by-Construction: Correctness meets Probability; 30 Years of Statistical Model Checking; Verification and Validation of Concurrent and Distributed Systems. Part II, Engineering Principles: Automating Software Re-Engineering; Rigorous Engineering of Collective Adaptive Systems. Part III, Applications: Reliable Smart Contracts: State-of-the-art, Applications, Challenges and Future Directions; Automated Verification of Embedded Control Software; Formal methods for DIStributed COmputing in future RAILway systems.

Formal methods have been applied successfully to the verification of medium-sized programs in protocol and hardware design. However, their application to the development of large systems requires more emphasis on specification, modelling and validation techniques supporting the concepts of reusability and modifiability, and their implementation in new extensions of existing programming languages like Java. The 6th International Symposium on Formal Methods for Components and Objects, FMCO 2007, was held in Amsterdam, The Netherlands, in October 2007. This book presents 12 revised papers submitted after the symposium by the speakers of each of the following European IST projects: the IST-FP6 project Mobius, developing the technology for establishing trust and security for the next generation of global computers; the IST-FP6 project SelfMan on self management for large-scale distributed systems based on structured overlay networks and components; the IST-FP6 project GridComp and the FP6 CoreGRID Network of Excellence on grid programming with components; the Real-time component cluster of the Network of Excellence on Embedded System Design ARTIST, focussing on design processes, and architectures for real-time embedded systems; and the IST-FP6 project CREDO on modeling and analysis of evolutionary structures for distributed services.

This book constitutes the refereed proceedings of the 10th IFIP WG 6.1 International Conference on Formal Methods for Open Object-Based Distributed Systems, FMOODS 2008, held in Oslo, Norway, in June 2008. The 14 revised full papers presented together with 1 invited lecture were carefully reviewed and selected from 35 submissions. The papers cover topcics such as semantics of object-oriented programming; formal techniques for specification, analysis, and refinement; model checking; theorem proving and deductive verification; type systems and behavioral typing; formal methods for service-oriented computing; integration of quality of service requirements into formal models; formal approaches to component-based design; and applications of formal methods.

This book constitutes the refereed proceedings of the 8th IFIP WG 6.1 International Conference on Formal Methods for Open Object-Based Distributed Systems, FMOODS 2006, held in Bologna, Italy, June 2006. The book presents 16 revised full papers together with an invited paper and abstracts of 2 invited talks. Coverage includes component- and model-based design, service-oriented computing, software quality, modeling languages implementation, formal specification, verification, validation, testing, and service-oriented systems.

This book constitutes the refereed proceedings of the 7th IFIP WG 6.1 International Conference on Formal Methods for Open Object-Based Distributed Systems, FMOODS 2005, held in Athens, Greece on June 15-17, 2005. The FMOODS conference was held as a joint event in federation with the 5th IFIP WG 6.1 International Conference on Distributed Applications and Interoperable Systems (DAIS 2005). The 19 revised full papers presented together with an invited paper were carefully reviewed and selected from 91 submissions. The papers are organized in topical sections on models and calculi, UML, security, composition and verification, analysis of java programs, Web services, specification and verification.
