Question

Comparing shorter vs. longer process cycles

I have identified multiple cooking cycles and noticed that some take significantly longer than others.

Possible contributing factors may include:

  • Steam pressure

  • Steam valve position

  • Product level

  • Initial product temperature

  • Cooling duration

What would be the recommended TrendMiner workflow to compare shorter versus longer cooking cycles and determine which process variables are most strongly associated with increased cooking duration?

Are there specific TrendMiner features that simplify this type of root cause analysis?

Hi ​@TIM  

This is a classic Event Analytics use case, start from your cycle search (the "Cooking Cycle" events), open Event Analytics, and add one calculation per suspect: avg steam pressure, avg steam-valve position, max product level, initial product temperature (start-of-cycle value), and cooling-stage duration.

Then use the three views in sequence — it's the community-recommended refinement triple:

  • Histogram of cycle duration to see whether long cycles are a distinct population.
  • Parallel coordinates brush the long-duration cycles and watch which factor axes separate with them. That visually nominates the culprits.
  • Scatter duration vs. the top suspect, with a regression line, to quantify the relationship.

Color-code by recipe/product if you run more than one, and filter startup/shutdown noise at the VBS level so the distributions stay clean.

Two resources that walk this through end-to-end: the Getting to the bottom of bad batches write-up, and the Event Analytics in Action VILT recording, which covers comparing performance across runs and turning the patterns into actionable insight.

Kind regards
