The main reference for VIKOR topic is work of Opricovic:
Opricovic, S., & Tzeng, G. H. (2004). Compromise solution by MCDM methods: A comparative analysis of VIKOR and TOPSIS. European journal of operational research, 156(2), 445-455.
But here you can find my work with application of TOPSIS and VIKOR and comparison which is downloadable in RG:
Yazdani, M., & Payam, A. F. (2015). A comparative study on material selection of microelectromechanical systems electrostatic actuators using Ashby, VIKOR and TOPSIS. Materials & Design (1980-2015), 65, 328-334.
