DEAHP based on ANP weight determination and its application to selection of reverse logistics service providers

In practical system evaluation problems, input and output indices are not independent and there are various complex relationships among them. Traditional DEAHP models directly use AHP to construct the restraint cone which may cause the deviation of weights errors. In this paper ANP is employed to determine the weights and reversely constructs the AHP restraint cone. Combined with DEA model, the DEAHP model is established and applied to the selection of reverse logistics service providers. The results show that DEAHP based on ANP weight determination can solve the problem of disable to distinguish several effective DMUs.
