Produktbeschreibung
This book fills a serious gap by providing a conceptual framework for understanding the digital world. This world contains large, heterogeneous systems that have to manage dynamic behavior as well as static items and data. Obviously, new, digital methods are needed to deal with the challenges of the digital world.

This book introduces such a method with Heraklit, an intuitively simple, albeit powerful framework for modeling, communicating, and analyzing computer-integrated systems. It integrates proven methods for composing modules, describing behavior with local cause and effect, and digitally representing real- and imagined-world items, resulting in a comprehensive, expressive, concerted, technically simple, digital modeling method.

This book is structured according to three Heraklit pillars, starting in Part I with the central Heraklit concept of modules, in particular their composition and refinement. Part II covers the second pillar of Heraklit, dynamics, focusing on modules that describe aspects of behavior. Part III focuses on static aspects. In particular, real- and imagined-world items and their symbolic representation are carefully distinguished and related. Together, these three pillars are consolidated in Part IV, integrating all concepts into a powerful formal framework. The book concludes in Part V with a more comprehensive case study of a typical retail business, recommendations on how to start modeling with Heraklit, and useful graphical conventions for the graphical representation of Heraklit models.

Heraklit covers the range from the first informal structuring ideas for a computer-integrated system, through the specification of (business) processes, the contributions of people, organizations, and mechanical devices, up to the construction of software. The book is therefore written for students in areas related to system modeling, system design, and system engineering, as well as for professionals in these fields.
Autorenporträt
Peter Fettke is a professor of Business Informatics at Saarland University and principal researcher, research fellow and group leader at the German Research Center for Artificial Intelligence (DFKI). He is interested in concepts, methods, and techniques at the intersection of business informatics and artificial intelligence, in particular the modeling of computer-integrated systems, robotic process automation, and systems mining. Peter is the author of more than 250 peer-reviewed publications and his work is among the most cited articles in leading international business informatics journals. Wolfgang Reisig is a professor emeritus for Software Engineering and Theory of Programing at the Computer Science Institute of Humboldt-Universität in Berlin, Germany. He was a professor at TU Munich in the 1990s. During his career he held visitor positions at ICSI in Berkeley, Technion in Haifa, TU Eindhoven, RMIT in Melbourne, University of Melbourne, and TU Vienna. Wolfgang is a member of the European Academy of Sciences, Academia Europaea. He has published and edited numerous books and articles on Petri net theory and applications.
