Many approaches of multiple criteria decision making has to selection of suppliers that Data Envelopment of Analysis (DEA) is one the useful methods. On the other hand, with considering the uncertainty in the real word, evaluation and suppliers selection problem becomes a complex decision problem. Grey theory is one of the theories that used for uncertainty condition. In this study to access real results in evaluation and selection of efficient suppliers, a developed grey data envelopment analysis model is presented that achieve with considering decision makers (DM) preferences about the inputs and outputs.
