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

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)

Editor's Notes

  • #2 Overall introduction: Check in on time frame – 3 hrs ish – short break at some point I’m where a different cap for next few hours – not Mr LineView – although there are some references here Some / quite a bit you may already know – apologies, such eggs, etc Empty your cup Be here fully Be interactive – up for challenge, ask questions as we go, you’ll get out what you put in Secondary outcome: Agree how to go allocate to fault level (for now)
  • #4 40% loss - what kind of problems, where, when, what exactly happened. Getting better or worse. Top level - Answer series of questions as glue Add new slide as top level overview – include vision Get prepared with some real data on faults, loss, etc Start with a mini session on LineView What’s the right data ensure we focus on the right areas? How can this be categorised in a useful way? How should the data be logged to make it most useful? How can we drill down to focus our efforts? How is machine data useful (over and above loss data)? What tools apply to what kind of problems?
