Digitalization seems to be the main drive towards sustainability in manufacturing, with one aspect of it being the digital twins for manufacturing processes. At the same time, sustainability, through its threefold character, namely addressing people, planet and profit aspects, introduces many different KPIs that need to be taken into account. Thus, adopting such a digitalized workflow, through a single manufacturing process digital twin network addressing sustainability, leads to also changing the workflow of a business, in order to harmonize materials and information exchange. The current work introduces a meta-modelling framework towards achieving heuristic modelling of a workflow and assessing the impact of the digital twins on the business workflows with respect to the complexity and potentially the profit of technology integration.
