Abstract:
The hesitation involved during the decision-making process lead to
uncertainty and difficulty in understanding the situation of the problems
occurs. However, there are lots of mathematical tools that described the
multiplicity, complexity and sensitivity of the human thoughts in the decision
process todays. One of the well-known methods frequently used by various
authors to handle this situation is Analytic Hierarchy Process (AHP). The
concept of AHP is commonly known as pair-wise comparison of decision
makers' assessment by applying the standard 9-points of preference scale
introduced by Saaty. The assessment made by decision makers however will
lead to failure due to the effect of vagueness. Thus instead of using the crisp
value as preference scale, fuzzy set theory is used to tackle the weaknesses.
