This book constitutes the refereed proceedings of the 1997 Ada-Europe International Conference on Reliable Software Technologies, held in London, UK, in June 1997. The 25 revised full papers presented were carefully selected for inclusion by the program committee. All current issues explored in the Ada community are addressed; beyond the Ada language aspects, software engineering technologies for reliable and for reactive systems are discussed in a more general context.

The Fourth International Conference on Reliable Software Technologies, Ada- Europe’99, took place in Santander, Spain, from June 7 to 11, 1999. It was sponsored by Ada Europe, the European federation of national Ada societies, in cooperation with ACM SIGAda and Ada Spain, and it was organized by members of the University of Cantabria and the Technical University of Madrid, in Spain. This was the 19th consecutive year of Ada Europe conferences, which have always been the main Ada events in Europe, with their counterparts being the ACM SIGAda conferences in the USA (formerly Tri Ada). The conference is not just devoted to the Ada language, but rather to the more general area of reliable software technologies. In this sense, there are papers on formal methods, testing, software architectures and design, software engineering tools, etc. We believe that the role of reliable software technologies is becoming increasingly important, as computer applications control more and more of our everyday systems. The goal of our conference is to contribute to advancing the state of the art of all the technologies that help us in achieving better and more reliable software at a lower overall cost.

The Sixth International Conference on Reliable Software Technologies, Ada- Europe 2001, took place in Leuven, Belgium, May 14-18, 2001. It was sponsored by Ada-Europe, the European federation of national Ada societies, in cooperation with ACM SIGAda, and it was organized by members of the K.U. Leuven and Ada- Belgium. This was the 21st consecutive year of Ada-Europe conferences and the sixth year of the conference focusing on the area of reliable software technologies. The use of software components in embedded systems is almost ubiquitous: planes fly by wire, train signalling systems are now computer based, mobile phones are digital devices, and biological, chemical, and manufacturing plants are controlled by software, to name only a few examples. Also other, non-embedded, mission-critical systems depend more and more upon software. For these products and processes, reliability is a key success factor, and often a safety-critical hard requirement. It is well known and has often been experienced that quality cannot be added to software as a mere afterthought. This also holds for reliability. Moreover, the reliability of a system is not due to and cannot be built upon a single technology. A wide range of approaches is needed, the most difficult issue being their purposeful integration. Goals of reliability must be precisely defined and included in the requirements, the development process must be controlled to achieve these goals, and sound development methods must be used to fulfill these non-functional requirements.

The refereed proceedings of the 8th International Conference on Reliable Software Technologies, Ada-Europe 2003, held in Toulouse, France in June 2003. The 29 revised full papers presented together with 3 invited papers were carefully reviewed and selected from numerous submissions. The papers are organized in topical sections on Ravenscar, language issues, static analysis, distributed information systems, software metrics, software components, formal specification, real-time kernel, software testing, and real-time systems design.

This book presents the refereed proceedings of the 1998 Ada-Europe International Conference on Reliable Software Technologies, Ada-Europe'98, held in Uppsala, Sweden, in June 1998. The 23 revised full papers presented together with two invited contributions were carefully selected by the program committee. The papers address all current aspects of the Ada programming language; they are organized in sections on Ada 95 and Java, Ada 95 language and tools, distributed systems, real-time systems, case studies and experiments, software quality, software development, software architectures, and high integrity systems.

This book constitutes the proceedings of the 23rd Ada-Europe International Conference on Reliable Software Technologies, Ada-Europe 2018, held in Lisbon, Portugal, in June 2018. The 10 papers presented in this volume were carefully reviewed and selected from 27 submissions. They were organized in topical sections named: safety and security; Ada 202X; handling implicit overhead; real-time scheduling; and new application domains.

The Ninth International Conference on Reliable Software Technologies, Ada- Europe 2004, took place in Palma, Spain, June 14–18, 2004. It was sponsored by Ada-Europe, the European federation of national Ada societies, and Ada- Spain, in cooperation with ACM SIGAda. It was organized by members of the University of the Balearic Islands (UIB). As in past years, the conference comprised a three-day technical program, during which the papers contained in these proceedings were presented, along with vendor presentations. The technical program was bracketed by two tutorial days, when the attendees had the opportunity to catch up on a variety of topics related to the ?eld, at both introductory and advanced levels. Furthermore, the conference was accompanied by an exhibition where vendors presented their products for supporting reliable-software development.
