| Summary: | This paper proposed a new sensitivity analysis
approach using the linguistic hedges in fuzzy environment. At the
first place, the linguistic hedge was briefly described with
emphasis on the two types, namely concentration and dilation.
Afterwards the power of concentration or dilation was employed
to represent the strength of the hedges. A fully linguistic variable
was used to assess the entire investigation attribute in a case
study. Lastly, the power of both hedge will changed into one level
up or down from the basis power for testing purposes. The results
show that, changing one level up or down power of the hedge
cause only small variations of the performance values and the
final ranking remains unchanged. Thus, it shows that our
proposed approach can be utilised to derive the robust model for
decision-making purposes. |
