Sensitivity Analysis Technique for Fuzzy TOPSIS using Improvised Sensitive-Simple Additive Weighting Method
ASM Science Journal · 2020
In the study of performance of decision-making methods, sensitivity analysis (SA) has been an important tool to check their stability and robustness.It is a tool to see the effect of the changes of certain parameters to the output.The investigation is usually focused on the alteration of the weight of the criteria in the problem and the changes to the output is analysed.This paper presents an SA technique using the Improvised Sensitive-Simple Additive Weighting (S-SAW) method to explore the stability of the fuzzy TOPSIS method, a well-known method in the field of decision making.The introduced SA offers a simpler and a systematic approach to performing SA and the effect of the changes are illustrated numerically and graphically.A numerical example on fuzzy TOPSIS is offered to demonstrate its effectiveness where to certain variation of inputs, the output values will be different from its original when the weights of criteria are altered.
