Designing Smart Services for a Component Manufacturer Based on a Digital Twin

Abstract

In the context of ongoing digitalization, manufacturing companies face new challenges and need to expand their portfolios to include new digital services. This paper describes how new digital services are designed for a component manufacturer in the context of a research project. The central enabler for the new digital services is the digital twin based on the asset administration shell (AAS) that makes the necessary data available. Existing approaches start from a standardized modeling form in order to design AAS submodels based on it. This paper is about the specification of functionalities for services as a basis for further modeling and, thus, also for AAS submodels. This paper results in a logically arranged set of methods that displays this approach. The essential steps are definition of the services’ basic functionalities, identification of the user groups for specific services, specification of user stories, and subsequent detailing and prioritization with the QFD method. The paper ends with an outlook on the ongoing research activities to define the application-specific AAS submodels.
