Asset Utilisation
Measure and report productive vs non-productive time for each station.
Beyond just tracking the number of production cycles completed, it can be particularly valuable to understand when the machine is directly engaged in the manufacturing process and what proportion of time the machine spends engaged vs idle. In Lean Six Sigma, this is related to the concept of 'Value Added Activity.
For example, in CNC machining, it may be useful to understand the amount of time spent running a program vs the machine being loaded or unloaded (even though loading and unloading is included in the cycle time).
Benefit
Identify and rectify unnecessary equipment stoppages.
Setup
For each station to be monitored, set a utilisation downtime threshold. This is the minimum number of minutes that should be considered as excessive downtime of the station.
Daily Workflow
Ensure a Non Production Schedule is entered for any stations that aren't planned to run to prevent downtime being wrongly recorded.
Busroot will automatically detect downtime based on the utilisation threshold settings.
Production manager will receive a notification that the station is stopped.
Operator or production manager will attribute a cause for the stoppage.
During team meetings, the previous days downtime reasons are reviewed and discussed.
