This Month's Tip : Using Performance Supervision Software

Some examples...

Before a planned shutdown, prioritized lists (based on economic weight) are extracted

  • Transmitters with problems
  • Sticky valves
  • Loops to be tuned

Weekly reports

Management
  • Area performance
  • Trends

Production
  • Sector performance
  • Percentage of loops that are not working in normal mode
  • 3 loops needing tuning
  • 3 loops where set point changes are frequent

Engineering
  • Prioritized lists of undersized valves
  • Prioritized lists of loops that are not in control

Maintenance
  • Prioritized lists of loops needing attention
  • Non performing areas

Actual situation

  • Treemap showing hot spots. For example, the following graphic illustrates a 1 000 loop system where:
    • Rectangle size represents the economic weight
    • Color represents the oscillation index of loops where oscillation comes from the valve
    • Hence, we are looking for large red rectangles!

We can help your team build and structure these reports…
