A modified VIKOR method for multiple criteria analysis.

The VIKOR method was developed to solve multiple criteria decision making (MCDM) problems with conflicting or non-commensurable criteria. This method assumes that compromising is acceptable for conflicting resolution. Although the VIKOR method is a popular method applied in multi-criteria analysis (MCA), it has some problems when solving MCDM problems. This study discussed existing problems in the traditional VIKOR method. The objective of this study was to develop a modified VIKOR method to avoid numerical difficulties in solving problems by the traditional VIKOR method. Several synthetic experiments were designed and assessed to verify the improvement of solution efficiency of the modified VIKOR method in MCA.
