Introduction to the book

Abstract

The system concept has existed for several decades now, but is still a viable concept to be used to denote a problem area and to adopt a holistic view. The essence of a system is that it consists of elements and relationships between these elements, and that it exerts a function in its environment, provided it is an open system. A system can be defined at different layers of abstraction consisting of subsystems, which themselves may consist of subsystems again. Themost complex level includes human beings. The system concept is adopted in Systems Engineering (SE) in which not only the engineering system under development is modeled, but also the development process itself in which many different disciplines need to be involved depending on the (lifecycle) requirements in focus. In this introductory chapter we draw the way we have paved to provide this book from the first idea on. The system concept, the origins, the goals and the expected audience of this book are roughly described. Finally, we give the first insight in the structure of this book and themutual interdependence of the chapters. This book contains many different contributions in the area of SE, categorized into 4 parts: an introduction to the concept, methods and tools, applications, and challenges.
