Multi-criteria optimization
The MCDM methods VIKOR and TOPSIS are based
on an aggregating function representing closeness to the
reference point(s). For the details of these two methods,
please refer to Tzeng and Opricovic (2003), which are
summarized in Appendices A and B. These two methods
introduce different forms of aggregating function (Lpmetric) for ranking. The VIKOR method introduces Qj
as a function of L1 and L
N; whereas the TOPSIS
