4. VIKOR Method

The VIKOR method was introduced by Opricovic in 1998 (Alinezhad and Esfandiari in J Optim Ind Eng 5:29–34, 2012 [16]; Amini and Alinezhad in Iran J Optim 8:111–122, 2016 [17]; Opricovic and Tzeng in Eur J Oper Res 178:514–529, 2007 [18]; Opricovic and Tzeng in Comput Aided Civ Infrastruct Eng 17:211–220, 2002 [19]. This technique is one of the compromising methods in compensatory models, as the closest alternative to the ideal solution is preferred in this subgroup. Generally, the technique focuses on the alternatives ranking and selecting an alternative with a set of contradictory attributes, and ultimately, provide a compromise solution, contributing the decision maker to reach the final solution. The VIKOR has been abundantly applied in decision making to select the ideal alternative since its introduction and has been used in analyzing the logistic outsourcing (Kumar et al. in J Manuf Technol Manage 23:885–898, 2012 [20]), selection of suppliers (Guo and Zhang in Selection of suppliers based on rough set theory and VIKOR algorithm. Shanghai, China, pp. 49–52, 2008 [21]), and airport location selection (Sennaroglu and Celebi in Transp Res Part D: Transp Environ 59:160–173, 2018 [22].
