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.

The 14th International Conference on Reliable Software Technologies - Ada- Europe 2009 - was part of a series of annual international conferences devoted tothepromotionandadvancementofallaspectsofreliablesoftwaretechnologies. The objective of this series of conferences, which is run and sponsored by Ada- Europe, the Europeanfederation of national Ada societies, is to providea forum to promote the development of reliable software both as an industrial technique and an academic discipline. This edition marked a return to France by selecting the splendid venue of Brittany, a region marked by its history with a strong Celtic tradition and a remotesituationatthewesterntipofthecontinentthatwastheinitiatorofmany explorers of new worlds... and information and communication technologies.

th The 13 edition of the International Conference on Reliable Software Technologies (Ada-Europe 2008) marked its arrival in Italy by selecting the splendid venue of Venice. It did so after having been hosted twice in Switzerland, Spain and the UK (Montreux for its inauguration in 1996 and Geneva in 2007; Santander in 1999 and Palma de Mallorca in 2004; London in 1997 and York in 2005), and having visited Sweden (Uppsala, 1998), Germany (Potsdam, 2000), Belgium (Leuven, 2001), Austria (Vienna, 2002), France (Toulouse, 2003) and Portugal (Porto, 2006). It was certainly high time that the conference came to Italy! The conference series, which is run and sponsored by Ada-Europe, chooses its yearly venue following two driving criteria: to celebrate the activity of one of its national member societies in a particular country, and/or to facilitate the formation, or the growth, of a national community around all aspects of reliable software technologies. The success of this year's conference, beside the richness of its technical and social program, will thus be measured by its lasting effects. We can only hope that the latter will be as good and vast as the former! Owing to the absence of a national society associated with Ada-Europe in Italy, the organization of the conference was technically sustained by selected members of the Board of Ada-Europe, its governing body, with some invaluable local support.

This book constitutes the thoroughly refereed post-proceedings of the 13th International Monterey Workshop on Composition of Embedded Systems: Scientific and Industrial Issues, held in Paris, France, in October 2006.

The 12 revised full papers presented were carefully selected during two rounds of reviewing and improvement from numerous submissions for inclusion in the book. The workshop discussed a range of challenges in embedded systems design that require further major advances in software and systems composition technology. The papers are organized in topical sections on model driven development and embedded systems, software engineering for embedded systems, and composition technologies.

Reliable Software Technologies is an annual series of international conferences devoted to the promotion and advancement of all aspects of reliable software technologies. The objective of this series of conferences, initiated and sponsored by Ada-Europe, the European federation of national Ada societies, is to provide a forum to promote the development of reliable softwares both as an industrial technique and an academic discipline. Previous editions of the Reliable Software Technologies conference were held in: Porto (Portugal) in 2006, York (UK) in 2005, Palma de Mallorca (Spain) in 2004, Toulouse (France) in 2003, Vienna (Austria) in 2002, Leuven (Belgium) in 2001, Potsdam(Germany)in2000, Santander(Spain)in1999, Uppsala(Sweden) in 1998, London (UK) in 1997 and Montreux (Switzerland) in 1996. The 12th International Conference on Reliable Software Technologies took place in Geneva, Switzerland, June 25-29, 2007, under the continued sponsoring ofAda-Europe, incooperationwithACMSIGAda.Itwasorganizedbymembers of the University of Applied Sciences, Western Switzerland (Engineering School of Geneva), in collaboration with colleagues from various places in Europe. The 13th conference, in 2008, will take place in Venice,

This book constitutes the thoroughly refereed post-proceedings of the 12th International Monterey Workshop on Networked Systems with special focus on realization of reliable systems on top of unreliable networked platforms, held in Laguna Beach, CA, USA, in September 2005.

The 6 revised full papers presented together with 10 papers contributed by the invited speakers were carefully selected during two rounds of reviewing and improvement from numerous submissions. Major issues covered by the workshop contributions are model-based software development of network-centric system-of-systems, foundations of future design and programming abstractions, active fault management in network-centric systems, intelligent and robust middleware, as well as model-based development of certifiable systems.

This book presents the thoroughly refereed and revised post-workshop proceedings of the 19th Monterey Workshop, held in Beijing, China, in Ocotber 2016. The workshop explored the challenges associated with the Development, Operation and Management of Large-Scale complex IT Systems. The 18 revised full papers presented were significantly extended and improved by the insights gained from the productive and lively discussions at the workshop, and the feedback from the post-workshop peer reviews. 2016 marks the 23rd anniversary for the Monterey Workshop series which started in 1993. For nearly a quarter of century, the Monterey Workshops have established themselves as an important international forum to foster, among academia, industry, and government agencies, discussion and exchange of ideas, research results and experience in developing software intensive systems, and have significantly advanced the field. The community of the workshop participants has grown to become an influential source of ideas and innovations and its impact on the knowledge economy has been felt worldwide.
