Master SAE AADL: the new international architecture notation standard for cost-effective model-based analysis and validation of mission- safety-critical software-reliant embedded systems. An indispensable resource for professionals throughout the aircraft, space, automotive, autonomous systems, and medical device industries, this book shows how to use AADL to systematically improve systems development through state-of-the-art architecture modeling, analysis, and validation. The first book on this crucial new standard, it presents all aspects of... MORE AADL notation in the context of an architecture-centric, model-based engineering approach to discovering problems earlier in the lifecycle, when they can be solved at lower cost. Co-authored by Peter Feiler, the AADL standard's author and technical lead, Model-Based Engineering with AADL is packed with real-world examples. Ideal for both self-learning and classroom instruction, and excellent reference for implementers,it compares AADL with other modeling notations and approaches, while presenting the language via a complete case study: the development and analysis of a realistic example system through repeated refinement and analysis. More than 30 leading industrial and government organizations have joined SAE to define and/or pilot the AADL standard -- including leaders like Boeing, Lockheed Martin, Rockwell Collins, DOD, FAA, NASA, ESA, JAXA, Airbus, BAE Systems, Honeywell, GE Aviation, and the US Army. This book gives you all the knowledge and insight you need to join them -- and to succeed in your own AADL initiative.

Conventional build-then-test practices are making today's embedded, software-reliant systems unaffordable to build. In response, more than thirty leading industrial organizations have joined SAE (formerly, the Society of Automobile Engineers) to define the SAE AS-2C Architecture Analysis & Design Language (AADL), a rigorous and extensible foundation for model-based engineering analysis practices that encompass system design, integration, and assurance. Using AADL, you can conduct lightweight and rigorous analyses of critical real-time factors such as performance, dependability, security, and data integrity. You can integrate additional established and custom analysis/specification techniques into your engineering environment, developing a fully unified architecture model that makes it easier to build reliable systems that meet customer expectations. Model-Based Engineering with AADLis the first guide to using this new international standard to optimize your development processes. Coauthored by Peter H. Feiler, the standard's author and technical lead, this introductory reference and tutorial is ideal for self-directed learning or classroom instruction, and is an excellent reference for practitioners, including architects, developers, integrators, validators, certifiers, first-level technical leaders, and project managers. Packed with real-world examples, it introduces all aspects of AADL notation as part of an architecture-centric, model-based engineering approach to discover embedded software systems problems earlier, when they cost less to solve. Throughout, the authors compare AADL to other modeling notations and approaches, while presenting the language via a complete case study: the development and analysis of a realistic example system through repeated refinement and analysis. This indispensable guide is comprised of the following: Part Oneintroduces both the AADL language and core Model-Based Engineering (MBE) practices, explaining basic software systems modeling and analysis in the context of an example system, and offering practical guidelines for effectively applying AADL. Part Two describes the characteristics of each AADL element, including their representations, applicability, and constraints. The Appendix includes comprehensive listings of AADL language elements, properties incorporated in the AADL standard, and a description of the book's example system.
