This book breaks new ground by presenting an interdisciplinary approach to a crucial problem – system dependability. Computer-based systems include hardware, software and people. Achieving dependability for such systems requires an interdisciplinary approach. In Structure for Dependability: Computer-Based Systems from an Interdisciplinary Perspective, computer scientists, sociologists, statisticians and psychologists bring together their latest research on the structure of dependable computer-based systems. The result is a highly readable overview of ways to achieve dependability in large computer-based systems with practical advice on designing dependable systems.Work on structure for dependability has usually come from a single discipline and has been concerned only with the computer systems. Stakeholders and system designers now agree that human and social issues cannot be separated from technical matters. The approach taken in this book demonstrates that interdisciplinarity delivers real benefits in the design and deployment of complex computer-based systems. This book is one of the outcomes of a six year Interdisciplinary Research Collaboration. Topics covered include fault tolerance, system evolution, determining software specifications, HCI, architecture, certification, dependability arguments, organisations, diagrams, time and procedures.System developers, stakeholders, decision makers, policymakers and researchers will find this book a unique resource which highlights the core issues for all those involved in improving dependability in complex computer-based environments.

Free Download Open Systems Dependability: Dependability Engineering for Ever-Changing Systems By Mario Tokoro
2012 | 192 Pages | ISBN: 1466577517 | PDF | 4 MB
This book describes how to achieve dependability in information systems. The author first proposes viewing systems as open systems instead of closed systems and presents Open Systems Dependability as a property for a system that has the ability to provide optimal services, minimize damage when stoppages occur, resume services quickly, and achieve accountability. He then outlines the DEOS process, an integrative process for achieving the desired dependability in information systems.

Over the last two decades, a major challenge for researchers working on modeling and evaluation of computer-based systems has been the assessment of system Non Functional Properties (NFP) such as performance, scalability, dependability and security.In this book, the authors present cutting-edge model-driven techniques for modeling and analysis of software dependability. Most of them are based on the use of UML as software specification language. From the software system specification point of view, such techniques exploit the standard extension mechanisms of UML (i.e., UML profiling). UML profiles enable software engineers to add non-functional properties to the software model, in addition to the functional ones. The authors detail the state of the art on UML profile proposals for dependability specification and rigorously describe the trade-off they accomplish. The focus is mainly on RAMS (reliability, availability, maintainability and safety) properties. Among the existing profiles, they emphasize the DAM (Dependability Analysis and Modeling) profile, which attempts to unify, under a common umbrella, the previous UML profiles from literature, providing capabilities for dependability specification and analysis. In addition, they describe two prominent model-to-model transformation techniques, which support the generation of the analysis model and allow for further assessment of different RAMS properties. Case studies from different domains are also presented, in order to provide practitioners with examples of how to apply the aforementioned techniques.Researchers and students will learn basic dependability concepts and how to model them using UML and its extensions. They will also gain insights into dependability analysis techniques through the use of appropriate modeling formalisms as well as of model-to-model transformation techniques for deriving dependability analysis models from UML specifications. Moreover, software practitioners will find a unified framework for the specification of dependability requirements and properties of UML, and will benefit from the detailed case studies.
