The use of digital concepts, such as the digital twin, increases the competitiveness of industrial companies. Various possible applications of a digital twin are described in the literature. However, in order to drive their implementation, it is necessary to quantify the resulting benefits for companies. Therefore, an approach is presented in this publication that allows the estimation of the economic and ecological benefits of using a digital twin for a company. First, possible applications are identified based on the product life cycle and then their use potentials for the company are analyzed. The use potentials are categorized according to direct, indirect, and strategic benefits. After the categorization, models are set up to quantify the direct and indirect benefits. Thus, the presented approach enables an evaluation of the benefit of using a digital twin for a company. Through a use case in additive manufacturing the function of the method was validated.
Additive Fertigungsverfahren ermöglichen die Herstellung von sowohl gleichen als auch unterschiedlichen Komponenten in einem Bauvorgang. Um insbesondere für die additive Serienfertigung eine gleichbleibende Bauteilqualität zu gewährleisten, kann der Einsatz eines digitalen Zwillings sinnvoll sein. Dieser stellt hohe Anforderungen an die Datenbasis in Bezug auf Strukturierung, Rechenleistung und Datensicherheit und muss auf die relevanten Funktionen des Einsatzbereichs zugeschnitten sein.
Additive manufacturing enables the production of both several identical and different components in a single printing process. To ensure consistent component quality, especially for additive series production, the application of a digital twin can be useful. This places high demands on the data basis in terms of structuring, computing power and data security and must be tailored to the relevant functions of the respective application.
