The current paper aims to fill this gap through case-based research, understanding from empirical data the application of Lean 4.0 in four UK companies. The findings showed that Lean 4.0 represents an excellent strategy to improve the manufacturingsystems' performance, mainly productivity, flexibility, real-time data accessibility, and quality control. Also, itwas possible to confirm that financial resources, adversity to change, and process complexity are the main barriers to Lean 4.0.

When AI interacts with humans in complex environments, such as aerospace manufacturing, safety of operation is of paramount importance. Trustworthiness of AI needs to be ensured through, among other things, explainability of its behaviour and rationale, which is typically a challenge for current deep neural network-based systems. We tackle the knowledge comprehensibility aspect of intrinsic explainability by suggesting a concept-level environment awareness model combining various complementary knowledge sources - statistical learning using dedicated property detectors through publicly available software, and crowd-sourced common-sense knowledge graphs. Our approach also addresses the issue of data-frugal learning, typical for environments with highly specific purpose-built artefacts. We adopt Gardenfors's Conceptual Spaces as a cognitively-motivated knowledge representation framework and apply our typicality quantification model in a use case on interpretable classification of manufacturing artefacts.

This paper describes how the application of the long short-term memory recurrent neural network (LSTM RNN) model can support the simulation-based digital twin (Sim.-based DT) of a manufacturing system in predicting the new outcome of production upon a changed parameter in the manufacturing setup. Simulation of the assembly production flow, as the only comprehensive ground-truth of the flow, represents the sequence and multi-factor dependencies of the assembly processes (associated with the spatial and environmental parameters) and renders a realistic realization of the production process. manufacturing digital twin (DT) has adopted such virtualization capability of the simulation [1] to capture, identify, and analyze the real-time abnormalities during the flow and mitigate the risk alongside the process. But simulation software systems are impotent in handling heavy detailed graphics, inflexible (by hard-coded logic) for optimization scenarios, and unresponsive to real-time changing parameters. This paper proposes a dual-layer LSTM RNN model, backed by three Dense layers, to be trained by the production simulation, so to render the generative pattern of the flow behavior and the predicted production outcome when the determinant parameters are changed in real-life. The final model will be a part of a bigger proposal for a hybrid optimization model, which is under development and not covered by the scope of this paper. However, the stand-alone proposed LSTM RNN model in this paper has capability to enhance the functionality of the Sim.-based DT in response to the real-time variations in determinant parameters. With the use of data from offshore wind turbine (OWT) generator's production line in Siemens Gamesa Renewable Energy (SGRE) Nacelle factory in Denmark and the corresponding simulation, a pilot model has managed to predict the total number of operators and their allocation to the workstations when a tact time is changed. This study denotes the logic behind the co

In order to prevent potential radioactive leaks and maintain personnel safety, fault diagnosis in nuclear power plants is crucial. knowledge-driven and data-driven approaches are two predominant directions in nuclear power plant fault diagnosis. knowledge-driven approach relies on prior professional knowledge, rules and model for state monitoring and diagnosis, offering strong logic and interpretability. However, it often yields poor results in complex systems. On the other hand, data-driven approach utilizes black-box inference to establish the mapping relationship between complex system characteristics and fault modes. However, this approach lacks interpretability in its operation mechanism, and it is deemed unacceptable for high-security industries such as nuclear power. To address these challenges, this paper introduces the concept of graph neural network and proposes an innovative idea of integrating knowledge-driven and data-driven approaches for fault diagnosis in nuclear power systems. The proposed method embeds the fault propagation path into the data-driven inference process by constructing a graph based on feature nodes and fault type nodes. Furthermore, we analyze how different methods of sampling features and aggregating data influence the diagnostic results during the process of inferring fault paths using graphs with corresponding fault labels. We implement and verify our scheme using a comprehensive simulation simulator for nuclear power devices. The results demonstrate that our method effectively carries out fault diagnosis by combining both interpretable graph-based inference with powerful nonlinear fitting capabilities offered by data-driven approaches.
