DigiTwin: An Approach for Production Process Optimization in a Built Environment

The focus of this book is an application of Digital Twin as a concept and an approach, based on the most accurate view on a physical production system and its digital representation of complex engineering products and systems. It describes a methodology to create and use Digital Twin in a built environment for the improvement and optimization of factory processes such as factory planning, investment planning, bottleneck analysis, and in-house material transport. The book provides a practical response based on achievements of engineering informatics in solving challenges related to the optimization of factory layout and corresponding processes.

Josip Stjepandic has had nearly a 35 year long career in research and development of complex industrial products and services. Since 1996, he has been working for PROSTEP AG, the leading consultancy for product data integration, where he is in charge of the business unit “3D product creation”. He has conducted many projects on engineering collaboration, supplier integration, CAD data exchange, knowledge-based engineering, intellectual property protection, development of design methods and systems engineering for leading global companies He has published numerous articles, and presented at several conferences.

Markus Sommer is Managing Director at isb GmbH, where he is responsible for the business development of the software company. His main focus is on new technologies (digital twin, process optimization using AI). With his degrees in electronics and technical informatics from the University of Applied Sciences Ravensburg-Weingarten, he started his professional career as a software developer for production and logistics. As a certified project manager, he successfully managed projects in electronics development with various activities in bus specification development, process management E/E and test management. Later he returned to his roots as head of the software development department. For many years he successfully led teams developing software for production and production planning.

Berend Denkena, born in 1959, is a trained machinist and studied mechanical engineering at the University of Hanover. He worked for Thyssen in Germany and the USA before joining Gildemeister Drehmaschinen in Bielefeld in 1996, where he was head of development and design. Since 2001, Denkena has headed the Insti-tute for Production Engineering and Machine Tools (IFW) at the Production Tech-nology Centre of Leibniz University Hannover. Here, around 80 research assistants work in the fields of machining processes, machine tools, production organisation and CFRP lightweight construction. Berend Denkena is the spokesperson for the Collaborative Research Centre 653 "Intelligent Components in the Life Cycle" and deputy spokesperson for the Collaborative Research Centre 871 "Regeneration of Complex Capital Goods". He also serves on various supervisory and advisory boards. He is a member of the International Academy of Production Engineering (CIRP) and the German Academy of Science and Engineering (acatech), among others.
