- Abstract
The real-world economic conditions have inevitably forced many companies to pursue outsourcing as a suitable long term planning tool to reduce operating costs and improve their competitiveness in different marketplaces. One of the critical activities for outsourcing success is the outsourcing provider selection, which may be regarded as a type of multi-criteria decision making (MCDM) problem. In this study, we propose a multiple-criteria group decision making model under interval-valued intuitionistic fuzzy environment to select the best outsourcing provider. First, an IVIF-weighted geometric averaging (IVIFWGA) operator is employed to aggregate all individual IVIF-decision matrices provided by a group of experts into a collective IVIF-decision matrix. Then, a new version of ELECTRE method in an IVIF environment by novel indexes is proposed for the evaluation process in terms of insufficient and inaccurate information. Finally, to demonstrate its usefulness, an application example for evaluating of outsourcing providers is given from the recent literature.
