By definition, OEE is based around total material output from a given machine. While OEE calculations can be set up to be unique per machine, anything which is not set to the standard for OEE calculations can cause trouble – ei3 does not recommend doing so. Doing so can create rare occurrences where the good […]
How are downtimes detected and extrapolated?
Machine downtimes are evaluated by the ei3 servers once every five (5) minutes. During each evaluation, the state of the machine is determined for each of the preceding data collection intervals. A machine is determined to be down whenever its speed falls below Minimum Production Speed. A machine is determined to be running whenever its […]
What is the maximum duration of a single downtime event?
The maximum duration of a continuous downtime event is 30 days. ei3 will automatically end a downtime event when its duration reaches 30 days, and then begin a new downtime event. © 2023 ei3 Corporation. Content of this web page is proprietary to ei3 Corporation.
How do changes in downtimes impact OEE calculations?
Whenever the machine is in a down state, a downtime event is automatically created in the system. Further, if a downtime code is assigned to the period, whether manually or automatically, the “type” of downtime code that is assigned can influence the calculation of OEE for that period of time. If the resulting downtime period is not […]
Why is my machine performance value above 100%?
A Performance value above 100% occurs when the calculated average speed of the machine is above the maximum speed entered in the machine data page. If the maximum speed is correct, check to make sure that the average speed being calculated by the system is correct. The average speed is computed by dividing the total units […]
