If
some of the input data are
uncertain, Spemann
PG-ROI offers
extensive sensitivity and
risk analysis.
Instead of assuming fixed
values, Spemann
PG-ROI accepts
ranges of input data. When
performing a multiple calculation
with changing input parameters,
the results are also within
ranges and can be displayed
in a graphic. |

In
this example, the positive
results of the modernization
are not certain,
for whatever reasons there
might be no additional power
output or the efficiency
might not increase from
41 to 43%. Then the benefits
of the modernization project
would be smaller and the
Pay-Off Time longer than
assumed initially.
The graphic displays the
whole range of Pay-Off Time,
which might be as long as
5 years instead 2.1 years
with an investment of 10
mEUR. |

| Even
though the price was reduced to
8 mEUR, the Pay-Off Time still
would be considerably higher,
so that simple reduction of price
would not make the project highly
beneficial, if the technical performance
does not improve. |
