Preface

It is the objective of this book to investigate what are the characteristics of simple versus complex systems and to find out what are the design principles that make a Cyber-Physical System understandable, simple to use, and easy to maintain. The adherence to these principles in the design of a Cyber-Physical System should lead to a significant reduction of the system complexity. The targeted audiences of this book are engineers, managers, and advanced students who are involved in the design and evolution of Cyber-Physical Systems and are willing to spend some time outside the silo of their daily work in order to widen their background and learn more about the pervasive problems of system complexity. My interest in the topic of complexity started when I was a manager of a process control department industry more than 40 years ago. This topic kept me hostage up to today. Forty years ago, the design of a process control system (today these systems are called Cyber-Physical Systems) was more of an art than an engineering endeavor. The software technology at that time was concerned primarily with functional correctness and did not pay much attention to the temporal dimension of program execution that is as important as functional correctness when a physical p
