Simple Additive Weighting Methods of Multi criteria Decision Making and Applications: A Decade Review

Various multi-criteria decision making (MCDM) methods have been proposed to solve diverse applications of decision problems. One of the MCDM methods is additive weighting-based method. However, this method is not explicitly disseminated and its applications are not-well received by many MCDM enthusiasts. This paper presents a review of the applications of simple additive weighting (SAW) and fuzzy simple additive weighting (FSAW) from 2003 to 2013. Two classifications of individual approaches and integrated approaches were made in this paper. Related articles appearing in international journals from 2003 to 2013 are gathered and analyzed. From the observation, it was noticed that ten out of nineteen articles or fifty two percent applied SAW or FSAW in the management selection process. This review provides the most prevalent application of the methods and also aids researchers in choosing the appropriate applications of SAW based methods. This paper would offer useful information for other researchers since it provides the latest evidence about SAW and FSAW.
