OEE a Deeper Understanding
In the perfect factory, equipment would operate 100 percent of the time at 100 percent of the designed capacity with an output that is 100 percent good. In real life, however, there are many planned and unplanned obstacles that prevent the equipment from operating continuously. The inability of equipment to reach full productive es from the time losses generated by downtime, speed and defect causes.
These three major category of losses are the foundation for understanding the effectiveness of the use of our equipment. OEE (Overall Equipment Effectiveness) is a metric used for monitoring and improving the efficiency of our manufacturing processes by measuring lost time and lost production.
The aim of OEE is to help in the identification, classification and systematic elimination mon sources for productivity losses. OEE measures the losses from line downtime that affect equipment "Availability", speed losses which affect "Performance" against designed speed, and defect losses which are the result of quality problems. Fully productive time is obtained after subtracting the time consumed by these losses from the original scheduled production time.
Calculating the overall equipment effectiveness (OEE) rate is a crucial element of any mitment to reduce equipment- and process-related wastes which increase cost but add no value.
OEE = Availability x Performance x Quality
By definition, OEE is the product of Availability, Performance and Quality percentages. During a regular workday, we plan for some periods where no production activity may take place such as lunches, breaks, meetings, maintenance or other event
