A Comparative Study of TOPSIS Method via Different Distance Measure
Pranjal Talukdar, Palash Dutta · International Journal of Research in Advent Technology · 2019
One of the techniques used to support strong decision making in domains where selection of best alternative is highly complex is the Fuzzy TOPSIS method.In TOPSIS procedure different distance measures are used to calculate the distance of each fuzzy number from both Fuzzy Positive Ideal Solution (FPIS) and Fuzzy negative Ideal Solution (FNIS).In this paper, six well known distance measures have been taken into account which are available in literature and applied to TOPSIS procedure to perform a comparative study throughout numerical problems.The main purpose is to compare the stability and reliability of TOPSIS method in decision science through different distance measures.Fuzzy triangular number is used in our entire case study.
