Anand, R., "Monitor and Optimize Machine Efficiency with OEE Dashboards," SAE Technical Paper 2010-01-0398, 2010, doi:10.4271/2010-01-0398.
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.
