AB  - Web services today are among the most widely used groups for Service Oriented 
      Architecture (SOA). Service selection is one of the most significant current 
      discussions in SOA, which evaluates discovered services and chooses the best 
      candidate from them. Although a majority of service selection techniques apply 
      Quality of Service (QoS), the behaviour of QoS-based service selection leads to 
      service selection problems in Multi-Criteria Decision Making (MCDM). In the 
      existing works, the confidence level of decision makers is neglected and does not 
      consider their expertise in assessing Web services. In this paper, we employ the 
      VIKOR (VIsekriterijumskoKOmpromisnoRangiranje) method, which is absent in the 
      literature for service selection, but is well-known in other research. We propose 
      a QoS-based approach that deals with service selection by applying VIKOR with 
      improvement of features. This research determines the weights of criteria based 
      on user preference and accounts for the confidence level of decision makers. The 
      proposed approach is illustrated by an example in order to demonstrate and 
      validate the model. The results of this research may facilitate service consumers 
      to attain a more efficient decision when selecting the appropriate service.
