Abstract
Decision-making (DM) holds a pivotal role in different spheres such as industry, healthcare, personal management etc. The multi-criteria decision making (MCDM) approaches includes choosing a prospective alternative from the set of available alternatives. Various DM techniques are utilized for choosing the optimal alternative and one such prominent technique is “Technique for order preference by similarity to ideal solution” (TOPSIS). This paper unfolds a review on TOPSIS technique of ordering of alternatives transitioning from real numbers to fuzzy set and further to the intuitionistic fuzzy set information.
Keywords: TOPSIS, MCDM, real numbers, fuzzy sets, intuitionistic fuzzy sets
