Statistical Process Control

Statistical Process Control (2 days)

Statistical Process Control (SPC) is a quality management technique that uses statistical methods to monitor and control processes. It involves collecting and analyzing data to determine if a process is in control or experiencing variations. SPC helps identify trends, detect deviations from desired performance, and enables proactive interventions to maintain process stability and improve overall quality. Applying statistical process control (SPC) on big data without sampling offers several advantages:

  1. Increased Accuracy: Working with the entire dataset rather than a sample provides a more accurate representation of the process behavior, as it captures all variations and patterns within the data. This accuracy allows for more precise control limits and insights into process performance.
  2. Enhanced Sensitivity: Analyzing big data enables greater sensitivity in detecting small process variations or anomalies that may not be evident in smaller samples. This increased sensitivity can help identify potential issues or opportunities for improvement that might have been missed with traditional sampling methods.
  3. Real-time / Inline Monitoring and Assessment: Big data analysis allows for real-time monitoring and control, providing immediate feedback on process performance. This enables timely interventions, proactive decision-making, and the ability to address issues before they escalate, leading to improved process stability and product quality.
  4. Scalability and Flexibility: SPC applied on big data offers scalability and flexibility, accommodating the ever-increasing volume, velocity, and variety of data generated in modern manufacturing processes. It enables the analysis of large datasets without compromising the representativeness or generalizability of the results.

This course introduces the basic concepts and principles underlying Statistical Process Control. Furthermore you will learn how to use Python software to execute all relevant SPC methods on large unsampled data volumes.

The theoretical topics of the training will be intensified by hands-on exercises, based on real-world IIoT datasets. By default, all exercises are performed with Python.
