Erratum to "A hybrid MCDM model for strategic vendor selection" [Math. Comput. Modelling 44 (2006) 749-761]

In a recent paper in this journal Shyur and Shih [1] propose a hybrid MCDM model for strategic vendor selection. In subsection 3.3 (Activity 2), the authors calculate the normalized decision matrix R(=[rij]). They calculate the normalized value rij as follows: rij = fij √ n ∑ j=1 f 2 ij , (1) where j = 1, . . . , n; i = 1, . . . ,m.By virtue of its TOPSIS feature, Eq. (1) is not correct. In fact the corrected formula is as follows:rij =fij√m∑i=1f 2ij.
