Book excerpt: Recently, contract-based design has been proposed as an "orthogonal" approach that complements system design methodologies proposed so far to cope with the complexity of system design. Contract-based design provides a rigorous scaffolding for verification, analysis, abstraction/refinement, and even synthesis. A number of results have been obtained in this domain but a unified treatment of the topic that can help put contract-based design in perspective was missing. This monograph intends to provide such a treatment where contracts are precisely defined and characterized so that they can be used in design methodologies with no ambiguity. In particular, this monograph identifies the essence of complex system design using contracts through a mathematical "meta-theory", where all the properties of the methodology are derived from a very abstract and generic notion of contract. We show that the meta-theory provides deep and illuminating links with existing contract and interface theories, as well as guidelines for designing new theories. Our study encompasses contracts for both software and systems, with emphasis on the latter. We illustrate the use of contracts with two examples: requirement engineering for a parking garage management, and the development of contracts for timing and scheduling in the context of the AUTOSAR methodology in use in the automotive sector.

Available in PDF, EPUB and Kindle. Book excerpt: "This book introduces the fundamentals of software contracts and illustrates how Design by Contract contributes to the optimal use of design patterns in a quality-oriented software engineering process. The Design by Contract approach to software construction provides a methodological guideline for building systems that are robust, modular, and simple." "Readers will find value in the book's overview of the Object Constraint Language, a precise modeling language that allows Design by Contract to be used with the industry standard Unified Modeling Language (UML). Although written in Eiffel, this book makes an excellent companion for developers who are using languages such as Java and UML. Throughout the book the authors discuss specific implementation issues and provide complete, ready-to-be-compiled examples of the use of each pattern." "They introduce design patterns and Design by Contract in the context of software engineering, and show how these tools are used to guide and document system design."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Download or read book Embedded System Design written by Peter Marwedel and published by Springer Science & Business Media. This book was released on 2010-11-16 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until the late 1980s, information processing was associated with large mainframe computers and huge tape drives. During the 1990s, this trend shifted toward information processing with personal computers, or PCs. The trend toward miniaturization continues and in the future the majority of information processing systems will be small mobile computers, many of which will be embedded into larger products and interfaced to the physical environment. Hence, these kinds of systems are called embedded systems. Embedded systems together with their physical environment are called cyber-physical systems. Examples include systems such as transportation and fabrication equipment. It is expected that the total market volume of embedded systems will be significantly larger than that of traditional information processing systems such as PCs and mainframes. Embedded systems share a number of common characteristics. For example, they must be dependable, efficient, meet real-time constraints and require customized user interfaces (instead of generic keyboard and mouse interfaces). Therefore, it makes sense to consider common principles of embedded system design. Embedded System Design starts with an introduction into the area and a survey of specification models and languages for embedded and cyber-physical systems. It provides a brief overview of hardware devices used for such systems and presents the essentials of system software for embedded systems, like real-time operating systems. The book also discusses evaluation and validation techniques for embedded systems. Furthermore, the book presents an overview of techniques for mapping applications to execution platforms. Due to the importance of resource efficiency, the book also contains a selected set of optimization techniques for embedded systems, including special compilation techniques. The book closes with a brief survey on testing. Embedded System Design can be used as a text book for courses on embedded systems and as a source which provides pointers to relevant material in the area for PhD students and teachers. It assumes a basic knowledge of information processing hardware and software. Courseware related to this book is available at http://ls12-www.cs.tu-dortmund.de/~marwedel.
Download or read book Tradeoff Decisions in System Design written by A. Terry Bahill and published by Springer. This book was released on 2016-12-14 with total page 716 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook is about three key aspects of system design: decision making under uncertainty, trade-off studies and formal risk analyses. Recognizing that the mathematical treatment of these topics is similar, the authors generalize existing mathematical techniques to cover all three areas. Common to these topics are importance weights, combining functions, scoring functions, quantitative metrics, prioritization and sensitivity analyses. Furthermore, human decision-making activities and problems use these same tools. Therefore, these problems are also treated uniformly and modeled using prospect theory. Aimed at both engineering and business practitioners and students interested in systems engineering, risk analysis, operational management, and business process modeling, Tradeoff Decisions in System Design explains how humans can overcome cognitive biases and avoid mental errors when conducting trade-off studies and risk analyses in a wide range of domains. With generous use of examples as a common thread across chapters this book. “This book provides an excellent road map for designing and producing competitive products.”

Book excerpt: A methodologically sophisticated, comprehensive approach to applying the Agile fixed-price contract to IT projects while maximizing customer and supplier relationships "Interesting and necessary for IT managers and IT lawyers." —Walter J. Jaburek, Dipl.-Ing., Dr. iur., Dr. techn. Approximately 50 percent of software developers use Scrum, an iterative and incremental development method for managing software projects and product or application development, in their work. The benefit of Scrum and other Agile methods is that they can address shifts in a large project that traditional managerial methods cannot. Written by pioneers and leaders in the field of Agile and Scrum, Agile Contracts is the only book dedicated exclusively to the legal, procurement, and project management considerations of Agile contracts. Providing templates, a toolbox, and examples of Agile fixed-price contracts, the book presents an alternative option to fixed-price, time-based, and supply-based contracts—reducing the risk for both the supplier and the customer with a contract that offers the possibility of flux and flexible scenarios as a project progresses. Agile Contracts features in-depth chapter coverage of: The Agile Manifesto of 2001 Agility from the perspective of procurement and the software provider The problems with traditional fixed-price contracts and time material contracts What the Agile fixed-price contract is and how it is set up Tendering based on the Agile fixed-price contract How to negotiate an Agile fixed-price contract Special guidelines for the legal framework of an Agile fixed-price contract Adaptable Scope System The Black Swan scenario Contracts and procedures for the featured methodologies Especially applicable within highly structured business organizations, Agile Contracts is a must-read for project managers, agile practitioners, procurement representatives, and IT lawyers.
Download or read book Design Pattern Contracts written by Jason Olof Hallstrom and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A design pattern describes a commonly recurring problem in the design of object-oriented software, a solution to that problem, and the context in which the solution can be applied. The benefits of design patterns are two-fold. First, patterns serve as guidance to the novice designer. Second, they provide an extended vocabulary for documenting software design. In the mid 1990s, the publication of several pattern catalogs -- compendiums of design patterns -- popularized patterns as a tool for designing object-oriented software. Unfortunately, the descriptive format popularized by these catalogs is inherently imprecise. As a consequence, it is unclear when a pattern has been applied correctly, or what can be concluded about a system implemented using a particular pattern. This ambiguity threatens to undermine the two principal benefits associated with the use of design patterns. First, novice designers are more prone to error without a precise description of how each pattern must be applied. Second, documentation describing the patterns applied in designing a system may be misleading, as different designers can interpret pattern descriptions in subtly different ways. To address the ambiguity issues associated with design pattern descriptions, we introduce the concept of a design pattern contract as a formalism for precisely specifying design patterns. Like all contracts, a design pattern contract consists of two primary components: a responsibilities component and a rewards component. The responsibilities component of a pattern contract precisely characterizes the requirements that must be satisfied by the designer when applying a particular pattern. The rewards component specifies the system properties that are guaranteed to be exhibited if the contract responsibilities are indeed satisfied. The contract formalism alone, however, is insufficient to guarantee that design patterns will be applied correctly. Even when guided by a precise set of requirements, designers can --- and do --- make mistakes. To detect such contract violations, we introduce the notion of a contract monitor --- an executable unit of deployment used to detect runtime contract violations. We present two approaches to implementing these monitors. The choice of which to use depends on the requirements of the system, and the skill-set of the designer.

Download or read book Design Science Methodology for Information Systems and Software Engineering written by Roel J. Wieringa and published by Springer. This book was released on 2014-11-19 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides guidelines for practicing design science in the fields of information systems and software engineering research. A design process usually iterates over two activities: first designing an artifact that improves something for stakeholders and subsequently empirically investigating the performance of that artifact in its context. This “validation in context” is a key feature of the book - since an artifact is designed for a context, it should also be validated in this context. The book is divided into five parts. Part I discusses the fundamental nature of design science and its artifacts, as well as related design research questions and goals. Part II deals with the design cycle, i.e. the creation, design and validation of artifacts based on requirements and stakeholder goals. To elaborate this further, Part III presents the role of conceptual frameworks and theories in design science. Part IV continues with the empirical cycle to investigate artifacts in context, and presents the different elements of research problem analysis, research setup and data analysis. Finally, Part V deals with the practical application of the empirical cycle by presenting in detail various research methods, including observational case studies, case-based and sample-based experiments and technical action research. These main sections are complemented by two generic checklists, one for the design cycle and one for the empirical cycle. The book is written for students as well as academic and industrial researchers in software engineering or information systems. It provides guidelines on how to effectively structure research goals, how to analyze research problems concerning design goals and knowledge questions, how to validate artifact designs and how to empirically investigate artifacts in context – and finally how to present the results of the design cycle as a whole.
Download or read book Social Systems and Design written by Gary S. Metcalf and published by Springer. This book was released on 2014-07-08 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: We live in the worlds that we help to create every day. Every activity either supports an existing system or effects some change, however small. But is it possible to consciously create the worlds in which we want to live? This volume brings together systems theorists and practitioners who have worked on that question for decades. It explores connections between design and systems ideas to explain why some efforts have been more successful than others, and what is needed if we are to move forward. It offers reflections on early and large-scale attempts at impacting societal systems, as well as proposals for taking those ideas into the future. Examples date back to the Club of Rome in the 1960s and look forward to the creation of ecologically sustainable systems in the future. They address the need for collaboration and inclusion in settings from communities to corporations. And while theories are presented as support for the examples, they are explained in practical ways meant to be accessible both to students and to general readers.

Available in PDF, EPUB and Kindle. Book excerpt: I am honored and delighted to write the foreword to this very first book about SystemC. It is now an excellent time to summarize what SystemC really is and what it can be used for. The main message in the area of design in the 2001 International Te- nologyRoadmapfor Semiconductors (ITRS) isthat“cost ofdesign is the greatest threat to the continuation ofthe semiconductor roadmap. ” This recent revision of the ITRS describes the major productivity improvements of the last few years as “small block reuse,” “large block reuse ,” and “IC implementation tools. ” In order to continue to reduce design cost, the - quired future solutions will be “intelligent test benches” and “embedded system-level methodology. ” As the new system-level specification and design language, SystemC - rectly contributes to these two solutions. These will have the biggest - pact on future design technology and will reduce system implementation cost. Ittook SystemC less than two years to emerge as the leader among the many new and well-discussed system-level designlanguages. Inmy op- ion, this is due to the fact that SystemC adopted object-oriented syst- level design—the most promising method already applied by the majority of firms during the last couple of years. Even before the introduction of SystemC, many system designers have attempted to develop executable specifications in C++. These executable functional specifications are then refined to the well-known transaction level, to model the communication of system-level processes.

Available in PDF, EPUB and Kindle. Book excerpt: Engineers encounter different types of contracts at nearly every turn in their careers. Contracts for Engineers: Intellectual Property, Standards, and Ethics is a tool to enhance their ability to communicate contractual issues to lawyers—and then better understand the legal advice they receive. Building on its exploration of contracts, this book expands discussion to: Patents, copyrights, trademarks, trade secrets, and other intellectual property issues Development of standards and the bodies that govern them, as well as conformity assessment and accreditation Ethics at both the micro and macro levels—a concept under major scrutiny after several major disasters, including the Gulf of Mexico oil spill, the collapse of Boston’s Big Dig, and a coal-mining accident that resulted in many deaths With a brief introduction to common law contracts and their underlying principles, including basic examples, the book presents a sample of the Uniform Commercial Code (UCC) regarding the sale of goods. It evaluates elements of the different contracts that engineers commonly encounter, such as employee and associated consulting agreements and contracts involved in construction and government. Approaching intellectual property from a contract perspective, this reference focuses on the many different types of patents and their role in commerce. It touches on the application of trademarks and recent developments in the use of copyright as a form of contract and explains the process of obtaining patents, including the rationale for investing in them. Ethical standards receive special attention, which includes a review of several prominent professional codes of ethics and conduct for both organizations and individual engineers, particularly officers and higher-level managers.
