OEE Software
Manufacturing efficiency leaders are using OEE as a true plant efficiency metric
that when measured and improved, improves cash flow, increases manufacturing capacity,
avoids capital equipment purchases and improves Capability to Promise (CTP) that
is worth hundreds of thousands of dollars per year.
Overall Equipment Effectiveness can be used to help focus on improving the performance
of machinery and associated processes by identifying those performance opportunities
that will have the greatest impact to the bottom line. Improvements in changeovers,
quality, machine reliability, working through breaks and more, can be measured and
improved utilizing the OEE metric.
OEE = Availability x Performance x Quality
There are many issues that can affect OEE, as shown in this pie chart:
Availability: available time - downtime / available time
Downtime losses can be calculated by adding together the amounts of time lost due
to equipment failures, setup adjustments, and changeovers.
Performance Rate: available time x processed amount / ideal cycle time
Speed losses are calculated by combining time lost due to minor stops, hesitations,
reduced speed and operator fatigue.
Quality Rate: processed amount - defect amount / processed amount
Defect amount is calculated by combining defects in process start up and reduced
yield.
The Informance solution allows manufacturers to rapidly deploy and automatically
track OEE–from the SKU/asset level, all of the way to the plant level. Major
and minor downtime is captured automatically, eliminating the need for inaccurate
manual systems.
Additionally, Informance allows OEE monitoring on the enterprise level by displaying every plant's OEE in one easy to access location. This makes it easy for executives to quickly recognize the best performing plants and the laggards. Once the laggards have been identified, the best practices from the top performing plants can be implemented there until all plants are performing at peak levels.
