The statistical samples in criteria-selecting stage were 92 people who were selected spontaneously, and also there were 8 people of the senior managers from each part in the ranking stage. In the first step it was specified by Cronbach and in the second step by the inconsistency coefficient of reliability of the questionnaires. In the next step the criteria was specified by biniminal test calculations, and finally we paid to classify them by FAHP which according to the obtained results, the quality criterion with 0.135 weights has the most important. The green production criterion with 0.131 weights is in the second priority. The geographical location criterion with minimum weight (0.075) is in the last priority. For testing this model, five suppliers were ranked; so we have: the first ranking is for the fourth supplier with 0.332 weights. The fifth ranking is for the sixth supplier with 0.133 weights.
