MIMOSA is
more than an organization developing open exchange
conventions. It is the enabling factor permitting
integrated maintenance management, a connection to
enterprise resource programs, and practical
profitability-related operations and maintenance.
Require your software vendors and program
administrators to use TDC guidelines, and MIMOSA
standards. This will reduce implementation cost,
enhance benchmarking tools, and insure your success.
Overall Equipment
Effectiveness
The overall performance
of a single piece of equipment, or even an entire
factory, will always be governed by the cumulative
impact of the three OEE factors: Availability ,
Performance Rate, and Quality Reject Rate. When I was
a speaker at an AFE convention in Las Vegas, to my
amazement the group did not know what OEE was. I was
in a major online chat session the other day where the
guest speaker was Robert Hansen, the author of the
book “Overall Equipment Effectiveness – A powerful
Production / Maintenance Tool for Increased
Profits”. What was the question being asked of him?
“What is OEE?”
Overall Equipment
Efficiency
Availability X
Performance X Quality= OEE
Availability -
Measures the percent of time that the equipment can be
used (usually total hours of 24-7-365 for equipment
utilization, or scheduled production time to result in
a reliability only measurement), divided by the
equipment uptime (actual production).
Performance -
The percentage of available time that the equipment is
producing product at its theoretical speed for
individual products. It measures speed losses. (e.g.,
inefficient batching, machines jams) If you can not
obtain equipment specifications from OEM, use best
recorded rate of pph/quality.
Quality -
Determining the percent of the total output (i.e. all
products including production, engineering, rework and
scrap ) that is good.
