The Technique for Order Preference by Similarity to
an Ideal Solution (TOPSIS) method is presented in
Chen and Hwang (1992), with reference to Hwang and
Yoon (1981). The basic principle is that the chosen
alternative should have the shortest distance from the
ideal solution and the farthest distance from the
negative-ideal solution.
The TOPSIS procedure consists of the following
steps:
(1) Calculate the normalized decision matrix. Th
