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 ?
?
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
Actionable Information
1. What’s the right data to focus on the right areas?
Causal (loss to critical machine
?
Right data - Faults vs Machine stops vs Causal loss
Line Stoppage
Machine Stoppage
Fault Detail
Right Stoppage Data?
Line Stoppage = Critical Machine Stoppage
WHY Stopped?
Due to another machine
True Causal Loss
Due to its own fault

Right data - MTTR & MTBFIdentify MTTR (Mean Time To Repair) and MTBF (Mean Time Between Failure) Targets based on the Accumulation space between the Machines
MTTR of M2 < Accumulation SpaceWhere, Accumulation Space = Dynamic conveyor capacity (containers)
Speed of feeding machine (M1)
MTBF of M2 > Recovery time to nominal stateWhere, Recovery time = Accumulation Space
Speed differential (M2-M1)
