Abstract: Inherent complexity and uncertainty in a business environment necessitates the consideration of conflicting multi criteria in the supplier evaluation process. In multi criteria supplier evaluation process, there are many decision situations in which the information cannot be assessed precisely in a quantitative form but may be in a qualitative one. This research aims to develop a computing tool which can evaluate the supplier by taking the opinion of expert as a linguistic value in a fuzzy form and incorporating the uncertainty measure. The use of linguistic labels makes expert judgement more reliable and informative for decision making. To address the uncertainty during decision making, Alpha-cut which is a fuzzy algebra, shall be used to get a crisp range from a fuzzy range. To enlighten the effects of uncertainty, objective of this research is to perform a sensitivity analysis using the range of truth-value using alpha-cut and see how the decision is affected.

Keywords: MCDM; fuzzy logic; alpha-cut; uncertainty; supplier evaluation; multicriteria decision making; sensitivity analysis.
