A Collaborative Design Methodology For The Design Of Embedded Control Systems

Collaborative Design for Embedded Systems

One of the most significant challenges in the development of embedded and cyber-physical systems is the gap between the disciplines of software and control engineering. In a marketplace, where rapid innovation is essential, engineers from both disciplines need to be able to explore system designs collaboratively, allocating responsibilities to software and physical elements, and analyzing trade-offs between them. To this end, this book presents a framework that allows the very different kinds of design models – discrete-event (DE) models of software and continuous time (CT) models of the physical environment – to be analyzed and simulated jointly, based on common scenarios. The individual chapters provide introductions to both sides of this co-simulation technology, and give a step-by-step guide to the methodology for designing and analyzing co-models. They are grouped into three parts: Part I introduces the technical basis for collaborative modeling and simulation with the Crescendo technology. Part II continues with different methodological guidelines for creating co-models and analyzing them in different ways using case studies. Part III then delves into more advanced topics and looks into the potential future of this technology in the area of cyber-physical systems. Finally various appendices provide summaries of the VDM and 20-sim technologies, a number of valuable design patterns applicable for co-models, and an acronym list along with indices and references to other literature. By combining descriptions of the underlying theory with records of real engineers’ experience in using the framework on a series of case studies the book appeals to scientists and practitioners alike. It is complemented by tools, examples, videos, and other material on www.crescendotool.org. Scientists/researchers and graduate students working in embedded and cyber-physical systems will learn the semantic foundations for collaborative modeling and simulation, as well as the current capabilities and limitations of methods and tools in this field. Practitioners will be able to develop an appreciation of the capabilities of the co-modeling techniques, to assess the benefits of more collaborative approaches to modeling and simulation, and will benefit from the included guidelines and modeling patterns.

Collaborative Design

Design occurs in a rich social context where the effectiveness and efficiency of social interaction and collective performance are key to successful outcomes. Increasingly, design is being explored and developed as a collective, collaborative, participatory, and even community process. The heightened recognition of designing as a social process has stimulated interest in collaborative design. This book contains the proceedings of the international conference "CoDesigning 2000" held in Coventry, England, September 2000. During this meeting exponents from a wide range of design domains came together to present and discuss perspectives on and new knowledge and understanding of collaborative design, and the evidence for enhanced design performance through collaboration. Within this volume different motivations for, conceptions of, and findings about collaborative design are addressed in 50 contributions by different research groups. Structured into 6 sections according to the main fields of interest, it provides a survey of the state of scientifically based knowledge and trends emerging from collaborative design research and their implications for a wide range of domains.
