Using AHP and L.P. for choosing the best alternatives based the gap analysis

Analytic Hierarchy Process is a well-known method that is only able to rank different alternatives according to their AHP weights, but it does not determine the necessary threshold for discriminate between acceptable and unacceptable alternatives. In the other words, it does not lead the DM to choose the alternatives that have higher weights than the threshold. In this paper, we introduce a new method by which we are able to accept/reject alternatives based on AHP weights. The proposed method determines the necessary threshold by comparing the anticipated status with the desired status of alternatives and using LP and AHP combination for it.
