A digital twinning reference model to facilitate multi-stakeholder decision-making

In product development, stakeholders aim to make decisions based on the available information. This information is not always complete, coherent, unambiguous, or reliable. By contextualising the information content, stakeholders from various perspectives are supported in decision-making. Currently, the available information is often process-centred, which originates from legacy systems and interfaces. The information needs to become perspective dependent to be relevant for all stakeholders involved. Perspective dependent information usage allows for adequate filtering and selection. To ensure sufficient flexibility in the uncertain context of product development, the digital twinning approach can be instrumental. This digital twinning approach supports in facilitating contextualised and unambiguous information for multiple perspectives. To allow for a structured and transparent digital twinning approach a sound foundation is required, for which this paper introduces a reference model. It facilitates a function-oriented development of digital twinning solutions, ensuring the integration of multiple perspectives. A use case scenario is used to verify and validate the reference model.
