Development of a ‘Digital Triplet’ Type Learning Factory

Abstract

We are proposing the concept of ‘Digital Triplet’ (D3) to support manufacturing system engineers in executing engineering processes, including Kaizen, by utilizing Digital Twin. The goal of our research is to verify the feasibility and advantage of D3 by embodying D3. For this purpose, we develop a learning factory based on the D3 concept. First, this paper describes the requirements of the learning factory. Next, we illustrate how to implement the learning factory and the results of the implementation. The developed learning factory consists of the three parts that correspond to the three worlds on D3, i.e., the physical, cyber, and intelligent activity worlds. Finally, this paper describes the difficulty we faced in the development and the insight gained from the difficulty.
