This study aims to experimentally confirm whether knowledge that has been challenging to transfer through traditional on-the-job training (OJT) can be effectively transferred by introducing a formalized OJT approach that describes the improvement process knowledge of skilled production systems consultants, facilitating imitation by unskilled consultants. We adopted the Digital Triplet (D3) concept, an extension of the authors’ digital twin framework to intelligent activities, aligning with our study objectives. Recognizing the difficulty and inadequacy of knowledge transfer in production systems consulting OJT, we propose an OJT support method integrating a decision-making modeling approach for skilled consultants’ processes based on the Generalized Production Systems Consulting Process Model (GCPM) from prior literature into traditional OJT methods involving self-learning and direct instruction. This method enables the construction of a domain-specific GCPM, formalizing the improvement process flow implemented by skilled consultants and linking it to production improvement expertise and tools. In a case study focused on energy-saving improvement, we constructed and tested a domain-specific GCPM’s efficacy in facilitating the transfer of difficult-to-transfer knowledge. The results indicate that domain-specific GCPM facilitates such knowledge transfer, including specialized improvement, knowledge utilization, rationale, and adaptation to specific cases.

“…Simultaneously, skilled engineers can gain insight into the significance of their own cognitive processes by studying the aforementioned more general and rational EPs. In the D3 concept, the modeling of skilled engineers' EPs is achieved using the Process Modeling Language for Digital Triplet (PD3, Version 2) [28], which describes the implementation process flow, knowledge, and tools employed by skilled engineers throughout the process with the expectation that they will be reused. The objective of D3 is to support the intelligent activities of production system engineers, assuming that a Cyber-physical Production System (CPPS) exists.…”

This study aims to analyze the process flow of skilled consultants who utilize production improvement know-how and digital technology to enhance production systems in external companies. The concept of a Digital Triplet (D3), which expands the authors’ Digital Twin framework to include the intelligent activity world, is adopted as it aligns with this study’s objective. Given the complexity of the problems faced by production system consulting and the resulting inadequacy of reusing decision-making processes of skilled engineers based on the Generalized Process Model (GPM) using D3, a production system consulting modeling method is proposed. This method incorporates the Generalized Production System Consulting Process Model (GCPM) to generalize the production system consulting process. Using the proposed method, a case study focusing on energy-saving improvements was conducted to describe and analyze the consulting process of skilled consultants. The results show that the proposed method effectively captures the process flow of skilled consultants while considering the iterative structure of the GCPM. Additionally, utilizing the GCPM enables a comprehensive view of the entire process, facilitating an understanding of how knowledge and tools are utilized in various contexts.

Digital Triplet" is a concept proposed to support manufacturing system engineers by combining the knowledge and knowhow of expert engineers with digital technology. This study proposes a method to represent engineering processes executed by engineers in a reusable manner based on Digital Triplet. Specifically, we develop a procedure to create a "log-level description" that records an engineering process as it is and a "generalized process model" that generalizes multiple log-level descriptions, using a process modeling language named "PD3" (Process Modeling Language for Digital Triplet). In a case study, expert engineers first executed engineering processes to improve production speed on a simplified production line. Next, log-level descriptions and a generalized process model were created for the engineering processes by the proposed procedure.Furthermore, an experiment was conducted on novice engineers using the generalized process model, and the results suggested that the model is effective for education. Currently, creating log-level descriptions or generalized process models is a laborintensive task as it is done manually based on the subjective judgment of the person representing the processes. However, we showed the application of "process mining" techniques has the potential to partially automate the task of creating the models.
