Driving OEE Improvements
Leaders in manufacturing efficiency use OEE as metric of plant efficiency to improve performance, cash flow, and manufacturing capacity,
and avoid capital equipment purchases and improve Capability to Promise (CTP). This approach can save or contribute hundreds of thousands or millions of dollars each year.
Overall Equipment Effectiveness helps in the effort to improve machinery performance
and associated processes by identifying performance opportunities
and evaluating which strategies 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 using the OEE metric.
OEE = Availability x Performance x Quality
There are many issues that can affect OEE.
Availability: available time - downtime / available time
Downtime losses can be calculated by adding time lost due
to equipment failures, setup adjustments, and changeovers.
Performance Rate: available time x processed amount / ideal cycle time
Speed loss is calculated by examining 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
Solarsoft helps manufacturers rapidly deploy and automatically
track OEE& #150; 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
Solarsoft also measures and monitors OEE at the enterprise level, displaying every plant's OEE in an easy-access format to help executives quickly recognize top performing plants and laggards. Using insight from top performers, executives can help laggards implement best practices so that all plants perform at peak levels.
