A2.4 Endurance ranged from 0 to 5, the increase in utility from swinging from the worst
to the best level would be smaller, probably resulting in a small weight for this
attribute. 113 Therefore, the DM was reminded that his judgment should always consider
the ranges of each attribute being assessed.
To assess the weights of the fundamental objectives, a similar procedure was
used, but the ranges were always between 0 and 1, since they are measured by their
respective utility functions.
When the multiplicative utility function was applicable, it was needed to define
the parameter k, which represents the interaction among all attributes that are part of that
particular utility function.
This step was accomplished using the software LDW, which provides a tool to
calculate the value of k. This feature consists of a comparison between lotteries 114 called
probability method (see fig. 32).
