Overall Equipment efficiency

  1. 1. KANZEN INSTITUTE ASIA PACIFIC 1 What is OEE ? OEE Overall Equipment Effectiveness Why is a high OEE important for the department ? OEE Calculation How can i influence the OEE ? Making OEE part of Visual Management OEE Definition
  2. 2. KANZEN INSTITUTE ASIA PACIFIC 2 Overall Equipment Effectiveness Total time e.g. 480 min. (1 shift) Available time Running time Productive time Effective time OEE is the way to measure how effectively machine / equipment hours are used (Value Adding) Planned Downtime Downtime Performance Losses Quality Losses OEE is loss due to: Depending on definition TPM® knows 6-16 different losses - breakdowns, repairs - changeover - adjustment - start up - machine speed - short stoppages - lower yield - scrap - reject - rework - breaks, planned maintenance, training
  3. 3. KANZEN INSTITUTE ASIA PACIFIC 3 Calculation of LOSSES Total time e.g. 480 min. (1 shift) Running time 340 min. Productive time 270 min. Effective time 250 min. Planned Downtime Downtime Performance Losses Quality Losses - breakdowns, repairs - changeover - adjustment - start up - long cycle time - minor stoppages - reduced yield - scrap - rework - rejects - breaks, planned maintenance, training Total losses = 170 min / shift Available time 420 min.
  4. 4. KANZEN INSTITUTE ASIA PACIFIC 4 Calculation of OEE Productive Performance= Running time - Performance loss Running time = 340 min – 70 min 340 min Quality = Productive time - Quality loss time Productive time = 270 min - 20 min 270 min Running Efficiency = Available time - Downtime Availability = 420 min - 80 min 420 min factor 81% factor 79.4% factor 92.6% X X = 59.6% OEE (in %) = Overall Equipment EffectivenessOverall Equipment Effectiveness
  5. 5. KANZEN INSTITUTE ASIA PACIFIC 5 How to increase OEE ? Data collection is the very important basis to increase OEE Collect data for all downtime and losses on the machine Data analysis and visible measure Make improvements visible and implement J F M A M J J A S O N D OEE Trend Target 2003 Analysis 5 10 15 20 25 30 35 Repair ChangeoverTool change Scrap Minor Stopp. 33 26 16 7 3 Repairs Change over, Adjustm.
