It also contains contributions by the three invited speakers at this event: Jos´e Meseguer, John Rushby, and Ketil Stølen. FACS 2011 was the eighth event in a series founded by the International InstituteforSoftwareTechnologyoftheUnitedNationsUniversity(UNU-IIST). The objective of FACS is to bring researchers and practitioners of component softwareandformalmethods togetherin orderto foster a deeper understanding of reliable component-based systems development and their applications, us- ing formal methods. The component-based software development approach has emerged as a promising paradigm to cope with the complexity of present-day softwaresystemsbybringingsoundengineeringprinciplesintosoftwareengineer- ing. However,many challenging conceptual and technologicalissues still remain inthetheoryandpracticeofcomponent-basedsoftwaredevelopment.Moreover, the advent of service-oriented computing has brought to the fore new dimen- sions, such as quality of service and robustness to withstand inevitable faults, that require revisiting established component-based concepts in order to meet the new requirements of the service-orientedparadigm. We received 46 submissions from 26 countries, out of which the Program Committee accepted 16 as regular papers, and, furthermore, conditionally ac- cepted 4 additional papers. The revised versions of 18 of these papers appear in this volume. Each submission to FACS 2011 was reviewed by at least three referees. Many colleagues and friends contributed to FACS 2011. First, we thank the authors who submitted their work to FACS 2011 and who, by their contribu- tions and participation, made this symposium a high-quality event. We thank the Program Committee members and their sub-reviewers for their timely and insightful reviews as well as for their involvement in the post-reviewing discus- sions. We are also grateful to the FACS Steering Committee for its guidance, to the invited speakers, and to Lucian Bentea for all his assistance in organiz- ing this event. Finally, we thank Andrei Voronkov for the excellent EasyChair conference system, and the ResearchCouncil of Norwayand the Department of Informatics at the University of Oslo for financially supporting the symposium.

Theirdistributedfeatures,theiradaptationneeds,andtheirreal-timeandprob- abilisticaspectsmakesuchsystemsquite complexandhardtodesign,buildand verify, yet their safety-critical nature makes their verificationessential. One im- portantsourceofcomplexity,causingmanyunforeseendesignerrors,arisesfrom ill-understood and hard-to-test interactions between their different distributed components. Methods to tame and greatly reduce system complexity are badly needed. System complexity has many aspects, including the complexity and associated cost of: – designing – verifying – developing – maintaining and – evolving such systems. The main goal of this talk is to propose the use of formal patterns as a way of drastically reducing all the above system complexity aspects. By a ”formal pattern” I mean a solution to a commonly occurring problem that is: – asgenericas possible, withprecisesemantic requirementsforits parameters – formally specified – executable, and – comes with strong formal guarantees. (cid:2) PartiallysupportedbyNSFGrantCCF09-05584,AFOSRGrantFA8750-11-2-0084, and Boeing Grant C8088. F.ArbabandP.C.O¨lveczky(Eds.):FACS2011,LNCS7253,pp.1–2,2012. (cid:2)c Springer-VerlagBerlinHeidelberg2012 2 J. Meseguer This means that a formal pattern can be applied to a potentially infinite set of concrete instances, where each such instance is correct by construction and enjoys the formal guarantees ensured by meeting the semantic requirements of the pattern’s parameters. The overall vision is that distributed systems should be designed, verified, andbuiltbycomposingformalpatternsthatarehighlygenericandreusableand comewithstrongformalguarantees.Alargepartoftheverificationeffortisspent in an up-front, fully generic manner, and is then amortized across a potentially infinite number of instances. As I show through concrete examples, this can achieveverydrasticreductionsinallaspectsofsystemcomplexity,includingthe formalverificationaspect. Itcanleadto high-quality,highly reliabledistributed systems at a fraction of the cost required when not using such patterns. Todevelopformalpatternsfordistributedsystemswithfeaturessuchasthose mentionedaboveanappropriatesemantic frameworkis needed, one supporting: – concurrency – logical reflection – distributed reflection and adaptation – real time and probabilities – executability, and – formal verification methods. I use rewriting logic as such a semantic framework, and illustrate with several examples its adequacy to specify and verify formal patterns of this nature.
