With a focus on software-intensive systems, this volume provides a comprehensive review of recent developments in intelligent systems, soft computing techniques, and their applications in manufacturing. To illustrate key ideas associated with requirements engineering, the text presents three example systems: an airline baggage handling system, a point-of-sale system for one location of a large pet store chain, and a system for a smart home in which one or more PCs control various aspects of the home’s functions. The selected systems encompass a wide range of applications.
