چکیده

In recent years, the problem of selecting and evaluating the suppliers in supply chain management has aroused considerable interest in business firms. Owing to the development of information systems, reaching an appropriate decision for adopting discrete methods is a need. The researchers intend to present a new model in this paper as a contributing factor in the grey environment in which the risk factor is evaluated high. The model decreases uncertainty in terms of two phases: A phase in parameter in terms of three -parameter interval grey numbers (the numbers are elicited from grey theory) instead of linguistic variables; in the other phase, we use a combination of AHP method and Bulls-eye method. A new method is used to rank suppliers that are due to generalization of ELECTRE I for three- parameter interval grey numbers named Grey-ELECTRE. Finally, a case study is brought to show application of the model in practical situation.
