Metrics
Measures the percentage of scheduled time a line is producing saleable product.
OEE
Planned Maintenance, Changeovers, CILs, Start-up/shutdown, planned utility outages, are all examples of.
Planned DT Loss
Are two types of loss trees
Throughput loss trees and Productivity loss trees
1-planned DT % - Unplanned DT % - Quality loss % - Rate loss %
Tactical OEE
Four buckets of break down losses.
Planned DT, Unplanned DT, Rate Loss, Quality Loss
Used for Reporting based on actual volume produced vs potential volume.
Strategic OEE
This is a way to organize data from Line Event Data Systems (LEDS)
Loss Trees
Helps teams understand the losses on their lines and prioritizes which top losses to address.
Loss analysis tool
Downtime / # of stops
MTTR
UPDT
Unplanned Downtime
Used in loss trees; highlights major areas of losses; drives decision-making and prioritization of loss elimination efforts.
Tactical OEE
Not at target speed; ramp-up/down are types of
Target rate losses
Tree used by the line structure team in DDS
Throughput loss tree
Net production / scheduled Time x Target Rate
Strategic OEE
True/False: You can normalize data down, but never up
True
The average time to repair a stop
MTTR (Mean Time To Repair)
Minor stops, breakdowns, process failures, lack of materials, blocked / starved conditions are examples of
Unplanned DT Losses
True/False; Pulling data for a loss tree beginning mid-week is acceptable after normalized?
False
Uptime / # of stops
MTBF
To create capability in each person and team to see and eliminate losses by systematically finding the root causes and by defining standards to eliminate those root causes and therefore, drive stability by creating standard work
Loss Elimination
The average time between stops
MTBF (Mean Time Between Failure)
Scrap and rework/recycle are types of
Quality losses
Tree used to target loss elimination or AM
Productivity Loss Tree
Risk + Action + Luck= Incident
Risk + Action = (no) Incident
OEE
Overall Equipment Effectiveness
