OEE facts

OEE Controversy
An informal survey of Automation World readers revealed a sizeable minority of the respondents—43 percent—have used OEE to compare the performance of equipment, production lines and even the manufacturers of equipment. But some argue that OEE neglects issues like loading factor, making it unsuited to such comparisons. TEEP calculations are more effective, they say.

TEEP = OEE x Loading Factor
Total effective equipment performance (TEEP) is the product of OEE and a loading factor computed by dividing planned uptime by calendar time. If you’re planning on running a line only one shift, rather than 24/7, then you have effectively a 30 percent loading factor on that line.
