This study aims to investigate the relationship between the use of digital twin (DT) and the overall equipment effectiveness (OEE) metric from the perspective of Lean 4.0.
A systematic literature review was conducted, and the resulting articles were subjected to a content analysis based on Bardin (2011). Using spreadsheets and graphical software, the data were organised to facilitate the presentation of the results.
The results characterise the DT into two groups, which address the level of integration of this system: “Partial interaction” and “Full interaction”. With this distinction made, we gathered the inhibitors related to the development of full DT integration, to detail opportunities and insights from the application of Lean 4.0, enabling the migration from one system to another and allowing operational excellence through the OEE indicator.
This study is limited by its theoretical approach, relying on a systematic literature review rather than empirical validation. It also highlights insights into how Lean 4.0 can be used by professionals to facilitate the transition from Partial Interaction to Full Interaction models for the integration of OEE measurements.
The novelty of this study lies in the application of Lean 4.0 to enable DT integration across production systems, filling a gap in the literature regarding the use of DT for tracking OEE as a tool to enable operational excellence.
