We present ManuKnowVis, a design study that contextualizes data from multiple knowledge repositories to enhance data-driven analyses in the manufacturing process of battery modules for electric vehicles. Our study reveals a discrepancy between knowledge providers, who have domain knowledge but struggle with data-driven analyses, and knowledge consumers, who lack domain knowledge but excel in data analyses. ManuKnowVis bridges this gap by enabling collaboration between providers and consumers and facilitating the creation and completion of manufacturing knowledge. The tool incorporates multiple linked views, allowing providers to describe and connect individual entities based on their domain knowledge, and consumers to leverage this enhanced data for more efficient data analyses.
We present ManuKnowVis, the result of a design study, in which we contextualize data from multiple knowledge repositories of a manufacturing process for battery modules used in electric vehicles. In data-driven analyses of manufacturing data, we observed a discrepancy between two stakeholder groups involved in serial manufacturing processes: Knowledge providers (e.g., engineers) have domain knowledge about the manufacturing process but have difficulties in implementing data-driven analyses. Knowledge consumers (e.g., data scientists) have no first-hand domain knowledge but are highly skilled in performing data-driven analyses. ManuKnowVis bridges the gap between providers and consumers and enables the creation and completion of manufacturing knowledge. We contribute a multi-stakeholder design study, where we developed ManuKnowVis in three main iterations with consumers and providers from an automotive company. The iterative development led us to a multiple linked view tool, in which, on the one hand, providers can describe and connect individual entities (e.g., stations or produced parts) of the manufacturing process based on their domain knowledge. On the other hand, consumers can leverage this enhanced data to better understand complex domain problems, thus, performing data analyses more efficiently. As such, our approach directly impacts the success of data-driven analyses from manufacturing data. To demonstrate the usefulness of our approach, we carried out a case study with seven domain experts, which demonstrates how providers can externalize their knowledge and consumers can implement data-driven analyses more efficiently.
