OEE or Overall Equipment Effectiveness is the metric that ties
machine availability, performance and part quality together. OEE is
calculated using the formula, OEE = Machine Availability x Machine
Performance x Quality of parts produced by the machine. The ideal
value for plant OEE is 100% which means all machines have zero
downtime, full availability and are not making any non conforming
parts.
Studies show that average OEE in the manufacturing industry is
about 60% whereas world class OEE is 85%. Most manufacturers have
room for improving their OEE. In order to improve OEE, this metric
needs to be monitored for all machines or equipment in the plant.
And there is nothing simpler than a dashboard to monitor OEE for
plant equipment. OEE dashboards can be used to - Monitor and
measure machine performance in real time, - Automatic data
collection guarantees accurate and timely machine information, -
Simple, easy to follow color coded dashboards make information easy
to consume, - From a single screen of the OEE dashboard, plant
Managers can find out performance of all machines in the plant, -
Improve machine efficiency, - Reduce machine and plant downtime, -
Operate plants at maximum efficiency, - Important investment
decisions can be made for buying new machines or upgrading to
better machines can be based off of the information presented in
the dashboard.
This white paper discusses the importance of monitoring OEE in
manufacturing plants and explains how OEE dashboards can help
reduce plant downtime, improve the bottom line.
