Abstract: Service-oriented business models become a key factor for business success and pave the way from the internet of things to the internet of services. The technological basis for these concepts are the digital model, the digital thread and the digital twin. From the digital model, often called the '150% model', an individual product is generated by customer- or order-specific instantiation. This is the core of the digital twin, which is enriched over the entire product life cycle, i.e., in development, production and later during operation via behavioural analyses, simulations and operating data. This paper presents definition of the digital twins developed over several research projects, as well as its derivation and management in a product lifecycle management (PLM) environment.

Keywords: digital twin; digital shadow; product lifecycle management; PLM; digital thread.
