This Springer essential is a translation of the original German 1st edition essentials, Von der Industrie 4.0 zum Geschäftsmodell 4.0 by Reinhard Ematinger, published by Springer Fachmedien Wiesbaden GmbH, part of Springer Nature in 2018.The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation.
