Actionable information 1

  1. 1. Improving Packaging Line Performance – Using the correct Data and Drill Down Analysis Actionable Information I www.optimumfx.com
  2. 2. Data…Data…Data == Good Information Excessive data – Lack of information The right data – with drill down analysis X Actionable Information
  3. 3. Actionable Information 1. What’s the right data to focus on the right areas? 2. How can this be categorised in a useful way? And Why? 3.How can we focus our efforts ? ?
  4. 4. The right data – Overall? • Production lines are designed around a CRITICAL MACHINE which is the slowest & typically most expensive item on the line - normally a filler / blow-fill • Line performance is measured based on the performance of this machine i.e. if it is running, the line is running, if it is slow, the line is slow • All other equipment should have the ability to run faster – than its neighbour (towards the Critical Machine) • Plotting these speed values creates what is known as a V-curve (normally more like a tick ) • Lines have in-built accumulation to prevent machine stoppages immediately impacting the upstream machines
  5. 5. Actionable Information 1. What’s the right data to focus on the right areas? Causal (loss to critical machine ?
  6. 6. Right data - Faults vs Machine stops vs Causal loss Line Stoppage Machine Stoppage Fault Detail
  7. 7. Right Stoppage Data? Line Stoppage = Critical Machine Stoppage WHY Stopped? Due to another machine Due to its own fault
  8. 8. Right data - Changeover/Set-up? 60,000 30,000 0 08:00 09:00 10:00 11:00 12:00 Time (hh:mm) Speedunitsperhour 07:00 Time 08:00 09:00 10:00 11:00 12:00 OEE 80% 0% 30% 60% 80% Changeover Metric Description Value Planned / Budget / Allowed Time Changeover time allocated in the production plan 90 mins Target Time Best time possible 75 mins Actual Time Time taken for last product in to first product out 85 mins 1st Hour OEE Measure of effectiveness of the changeover 50% Changeover/ set-up time NB – All values are example data to illustrate the metrics and the diagram is not to scale
  9. 9. Right data - MTTR & MTBF Identify MTTR (Mean Time To Repair) and MTBF (Mean Time Between Failure) Targets based on the Accumulation space between the Machines MTTR of M2 < Accumulation Space Where, Accumulation Space = Dynamic conveyor capacity (containers) Speed of feeding machine (M1) MTBF of M2 > Recovery time to nominal state Where, Recovery time = Accumulation Space Speed differential (M2-M1) M2M1 M1 M2Nominal State Accumulation Full
  10. 10. Actionable Information 1. What’s the right data to focus on the right areas? Causal (loss to critical machine Actual time Machine stoppages PDT/NOP 2. How can this be categorised in a useful way? And Why? ?
