Screening and Controlling Manufacturing Processes


See how to:

  • Use  Process Stability, Process Screening and Predictive Screening to help control  complicated manufacturing processes
  • Screen processes for many (1000+) process variables over time to determine process stability
    • Import multiple files and format for process analysis
    • Screen for outliers by quartile range and handle outliers as appropriate
    • Save outlier cleanup script for future use
    • Screen for missing values
    • Use Process Screening Control Chart to examine quality trends
    • Interpret Stability Index to locate less stable subgroups
    • Identify questionable areas and run Indivdual Moving Range Charts to examine and identify possible cause of variation
  • Determine process capability
    • Interpret 4-quadrant Process Performance Plot to compare and assess capability and stability combinations
    • Drill into Control Charts for variable of interest
  • Screen historical data to find variables most likely to impact your process
  • Use Model-Drivien Multivarate Control Charts to monitor parameters for multiple processes
    • Interactively explore and understand the underlying components that lead to out-of-control signals
