Ranking of fuzzy numbers is not an easy task as fuzzy
numbers are represented by possibility distributions and they can
overlap with each other. Since it was introduced, various
approaches on ranking fuzzy numbers have been proposed. The
recent ranking fuzzy numbers proposed by Wang and Li is
claimed to be the improved version in ranking. However, the
method was never been simplified and tested in real life
application. This paper presents a four-step computation of
ranking fuzzy numbers and its application in ranking indicators
of health related quality of life. The four steps algorithm was
proposed as to establish ranking and followed by a testimony in
health related symptoms among elderly. Data in form of
linguistic terms were collected from three experts at State of
Terengganu Malaysia. Decisions were made based on the
centroid-point ( x, y ), where the degree of representative
location ( x ) is higher than average height ( y ). These points
permit to characterize the evaluation behaviour of each indicator.
The ranking reflects the problematic level of elderly people. The
results show the feasibility of the proposed stepwise computation
in real application.
