Overall Equipment Effectiveness (OEE)

DefinitionOEE
OEE is a world-wide standard to measure the success of total productive maintenance (TPM) activities and other initiatives from Bosch Production System which are oriented at reducing losses / non value added activities for an equipment. OEE is defined as a measure of utilisation for an equipment for the time it is planned to be used. It excludes all planned downtimes (e.g breaks, plannedmaintenance, training etc), but includes setups or change over losses. By doing that OEE shows how effectively planned time was used for producing good parts. OEE accounts for the following losses: Availability losses (duration > 5 min e.g: lack of material and personal, changeovers/Setups, breakdowns, unplanned maintenance). Performance losses. Quality losses.

OEE Calculation
Our line is operating at 85%! I wonder how you calculated this figure?

Methods to calculate machine utilisation rate vary considerablydepending on site and thus make comparisons extremely difficult. Overall Equipment Effectiveness (OEE) is a standardised methodology to calculate machine utilisation.

Overall Equipment Effectiveness (OEE)

Terms
Total availability : 24 hrs / day. Planned downtime [ hrs or minutes ]: Duration for which equipment is not used, rest periods, breaks or pause for operators, training. All suchduration are excluded. Planned maintenance [hrs or minutes ]: Duration TPM activities or planned maintenance activities are excluded. Planned operating time: = Total availability - Planned downtime – Planned Maintenance Cycle time: In a line with a number of stations, cycle time taken for OEE calculation is cycle time from the slowest station. For machines cycle time used is as indicated in...
