Quality prediction

Quality innovation through the intelligence of process data

OVERVIEW

From inspecting for defectsto predicting them away

Quality management moves from after-the-fact inspection to prediction while the process runs.

  • Illustration of after-the-fact inspection with process waste and recycling

    01Defects that surface only at the end

    Quality is judged at final inspection, so a defect shows up in parts that are already made — long after the process condition that caused it has passed.

  • Operator inspecting laser processing equipment

    02Limits of root-cause analysis

    When a problem occurs, the root cause is hard to identify, and quality management keeps relying solely on the personal experience of highly skilled operators.

  • Stacks of cash and a factory model depicting rising costs

    03Lower cost efficiency

    Quality issues increase work-in-process and rework volume, so production time grows longer and manufacturing costs rise

KEY FEATURES

Four capabilities that turn quality into prediction

From real-time detection through factor analysis and defect prediction to process optimization.

Quality Capability

01 / 04

01

Real-time anomaly detection

Data from the various sensors and equipment installed across the process is collected in real time and visualized on a dashboard. The state of the production floor can be grasped at a glance, providing the visibility to respond immediately to unexpected stoppages or errors.

Management Scope

  • Sensor data collection
  • Real-time monitoring
  • Equipment utilization analysis
  • Integrated data management
  • On-site status board integration
  • Anomaly alerts

EFFECT

Business impact

What it leaves behind — in defect rate, rework, unit cost and productivity.

  • A 3D illustration linking process equipment and sensors, databases, analytics, and inspection gear to an AI core
  • 01

    Lower defect rate

    Trend analysis corrects small deviations automatically, and machine learning finds what degrades quality so optimal conditions are set quickly.

    Defect ratequality variationset-points
  • 02

    Less rework

    The predicted defect probability is fed back into the process conditions, so less comes back for rework at all and the line no longer stalls waiting to re-run it.

  • 03

    Lower unit cost

    Scrapping a finished part is avoided, and the energy cost per unit of stable quality plus post-shipment logistics and warranty cost come down.

    Higher productivity

    Time data locates the bottleneck and immediate feedback corrects the conditions, lifting the hourly output the same equipment delivers.
