This title provides a clear overview of the main methods, and has a practical focus that allows the reader to apply their knowledge to real-life situations. The following are just some of the techniques covered: UML, Z, TLA+, SAZ, B, OMT, VHDL, Estelle, SDL and LOTOS.

Objectives of this Book This book is an introduction to a set of software specification methods. Its tar­ geted audience are readers who do not wish to read pages of definitions in order to understand the basics of a method. The same case study is used to introduce each method, following a rigorously uniform presentation format. Special care has been devoted to ensure that specifications do not deviate from the case study text. As much as the method allows, what is specified is what appears in the case study text. The benefits are two-fold. First, the reader can easily switch from one method to another, using his knowledge of the case study as a leverage to understand a new method. Second, it becomes easier to compare methods, because the same behavior is specified in each case. Each method presentation follows the same pattern. The concepts are pro­ gressively introduced when they are needed. To illustrate the specification pro­ cess, questions that the specifier should raise during the analysis of the case study are stated. Answers are provided as if they were given by an imaginary client. The question/answer process guides the derivation of the specification. Interestingly, the questions raised depend on the method, which is illustrative of the differences between them.

ABZ 2010 was held in the beautiful natural setting of Orford in the Eastern Townships of Qu' ebec,during February22-25,2010,midwaythroughthe Ca- dian winter and the 21st Winter Olympics, bringing participants from all over the world to brave this rigorous climate. ABZcoversrecentadvancesinfourequallyrigorousmethodsforsoftwareand hardware development: Abstract State Machines (ASM), Alloy, B and Z. They shareacommonconceptualframework,centeredaroundthe notionsofstateand operation,andpromotemathematicalprecisioninthemodeling,veri?cation,and construction of highly dependable systems. These methods have continuously matured over the past decade, reaching a stage where they have been successfully integrated into industrial practice in various areas like trains, automobiles, aerospace, smart cards, virtual machines, and business processes. Their development is in?uenced by both research and practice, which mutually nurture each other. ABZ has both a long and a short history. With the aim of stimulating cro- fertilization between these four methods, it has merged their individual conf- ence and workshopseries which started in 1986 for Z, 1994 for ASM, 1996 for B, and 2006 for Alloy. The ?rst ABZ conference was held in London in 2008; ABZ 2010 is the second edition.The conference remains organized as four separate Program Committees.
