The Strategic Importance of Plant Reliability
It is often misunderstood that effective reliability management
of a manufacturing plant is merely a process of
performing maintenance better. It is much more than that.
In a manufacturing enterprise two important Key Performance
Indices are used – one for the production side, called
Overall Equipment Effectiveness (OEE), and the other on the
enterprise side, called Overall Management Effectiveness
(OME). Both of these key indices have a direct dependency on
an attribute called Plant Reliability.
For purposes of clarity, by Plant Reliability we mean the
overall reliability of the production assets in the shop floor. In
a shop floor production flow line, Plant Reliability is determined
by the measures of reliability of the individual assets.
The asset that has the maximum failure rate becomes the
weakest link. As a result of a single asset or a group of assets
not being very reliable, it is quite possible that the overall
Plant Reliability can be adversely impacted – and more
importantly, the return on the investment and profitability as
well get impacted along with it.
