Empowering Industry 4.0: Predictive AI Analytics for Component Self-Diagnostics

The relentless progress of Industry 4.0 is reshaping the manufacturing landscape, with AI-driven innovations leading the way. In the Deliverable D2.3 ‘Predictive AI analytics for component self-diagnostics’, the AI-PROFICIENT team focuses on the strides made within Work Package 2 (WP2) – Smart Components and Local AI at System Edge. In this blog post, we unveil the essence of this deliverable, which focuses on predictive AI analytics for component self-diagnostics.

In specific, the Deliverable D2.3 takes us into the heart of WP2’s endeavors, where cutting-edge technologies are harnessed to develop edge systems that diagnose the very assets they are integrated within or control. This deliverable is a testament to the project’s commitment to transforming asset management through state-of-the-art diagnostics.

In the context of Industry 4.0, diagnosis services emerge as a pivotal element. These services ‘can be used by higher level systems to optimize asset operation in coordination with other assets; or, by other edge systems that could modify their controls adapting them to the current condition of the controlled asset’.

Within this deliverable, Kerman Lopez de Calle (TEK), Alejandro Muro (TEK), and Alexandre Voisin (UL) aim to disseminate various diagnosis strategies employed for asset monitoring. In addition, the AI-PROFICIENT team presents different use cases were AI based diagnostic technologies have been validated, together with the corresponding technical dissemination of these advances.

      How does Machine Learning relate to AI?

      Answer
      Machine Learning is a subset of AI
      Machine learning is a subset of AI. The idea is that machines will “learn” and improve at tasks over time rather than having humans continually input parameters. Machine learning is a practical application of AI.

      What is Neural Networks?

      Answer
      Is a method in artificial intelligence that teaches computers to process data in a way that is inspired by the human brain​
      Neural networks are a class of machine learning algorithms. The neuron part of the neural is the computational component, and the network part is how the neurons are connected. Neural networks pass data among themselves, gathering more and more meaning as the data moves along. Because the networks are interconnected, more complex data can be processed more efficiently.​

      By how much percent AI implementation decreases raw material waste in tyres production?​

      Answer
      8%
      Combining Explainable AI algorithms with the global optimisation algorithms in the rubber extrusion allows continuous suggestion of the operator's optimal machinery parameters. This reduces the time when the rubber extrusion process is set and thus reduces the time when the suboptimal rubber outcome that cannot be used in further tire production.

      Which of the following is a polymer extrusion process:​

      Answer
      A chemico-mechanical process​
      Chemically, the process involves the melting and flow of a polymer material under heat, which can result in chemical reactions such as degradation or cross-linking of the polymer chains. The chemical properties of the polymer material and the extrusion conditions, such as temperature, pressure, and residence time, can affect the final properties of the extruded product.​

      Mechanically, the process involves the deformation of the molten polymer material under pressure as it is forced through a die orifice to form a continuous shape. The mechanical properties of the polymer material, such as its elasticity, viscosity, and melt strength, determine its ability to withstand the stresses and strains imposed during the extrusion process.​

      Which are the key elements of an optimization problem:​

      Answer
      The objective function, the decision variables and the constraints​
      The objective function defines the goal of the optimization problem, whether it is to maximize or minimize a certain value. The decision variables are the variables that can be adjusted or controlled to achieve the optimal solution to the objective function. The constraints are the limitations or restrictions that must be satisfied during the optimization process.​

      The other two options mentioned in the question are not related to the key elements of an optimization problem. Hyperparameters, validation schemes, and accuracy metrics are more related to machine learning or data science problems. The differential hypothesis is not a common term used in optimization problems. ​

      When the blade of the cutting system starts to wear out but it can keep cutting:​

      Answer
      It might work well but chances are eventually it will compromise the quality of the final product.​
      As the blade of the cutting system starts to wear out, it will gradually lose its sharpness and efficiency, which can affect the quality of the cut and increase the cutting forces. If the blade is allowed to continue cutting even after it has worn out, it can lead to several negative consequences.

      Answer
      Workpiece factor, feed factors and saw blade factors​
      In a well-controlled manufacturing environment, the cutting process should be designed to be robust and less sensitive to operator variation. Regarding to the environmental factors, they are less significant compared to other sources of variation.

      Developing the AI service which will improve tread alignment in part of the Combiline depends upon marking pictures of the tread pieces, which will then be used to train the AI. How should the developers and industrial partner approach this picture marking task for AI training?​

      Answer
      The developers should clearly specify how many pictures need to be taken, how long the process will take, and discuss with the industrial partner who will do it.​
      An ethical approach to this task involves clearly specifying how many pictures, and how much added work time it involves. On that basis the developer can discuss with the industrial partner who should do the task, e.g. whether the developers themselves are better placed to do it, or whether the industrial partner’s operators should do it. If the latter, it should be made clear to the operators whether they can refuse to do it, or it is an obligation which makes up part of their work. ​

      Answer
      XAI stands for "explainable artificial intelligence" and it can help in manufacturing by improving process control, enabling predictive maintenance, enhancing quality control, and improving safety.​
      XAI stands for explainable artificial intelligence and provides insights into decision-making processes, identifies patterns and anomalies in equipment data, and detects defects in real-time. This allows manufacturers to make better decisions, reduce downtime and maintenance costs, and address problems quickly.​

      How should the developers engage the operators when developing the AI service and related apps and HMIs, with the goal of simplifying the job of confirming correct chemical product bag placement before production? ​

      Answer
      The developers should work closely with the operators to design the services, choose the HMIs and adapt the apps, according to the actual work context. ​
      To implement an ethical by design user centered approach, the developers should work closely with the operators who will actually use the service. They should take care to understand the specific work conditions (dust, noise, time for tasks, etc.), discuss the planned solutions with the operator users, design initial mockups and discuss these with the operator users regularly in an iterative process as they develop the service. ​
