Tom Saaty developed the analytic hierarchy process (AHP) more than 25 years ago. Since then, AHP has been used by decision makers all over the world to model problems in diverse areas such as conflict analysis, marketing, R&D management, strategic planning, and public policy. Thousands of AHP papers have been published, documenting the wide applicability of the approach in ranking, selecting, e...

The Analytic Hierarchy Process (AHP) has been considerably criticized for its possible rank reversal phenomenon. Many variants of the original AHP have been proposed to preserve rank orders. The validity of the original AHP and its variants have been a subject of long-lasting debate. In this paper we propose four criteria to evaluate the validity of AHP aggregation rules and examine three typic...

A comparison is made between the most commonly used decision-making method (AHP), and two methods developed by the authors (APM and CSM). It is shown that the newly developed methods do not change the correlations and types of inequalities between the global priorities of the alternatives when the number of alternatives changes. This differentiates them from the AHP, which does change them. Als...

Any decision is closely linked to the quality and availability of information. Innovative methodologies are proposed to help decisions based on imperfect information provided by more or less reliable and conflicting sources in uncertain context. These methods combine new uncertainty theories and multicriteria decision making. The ER-MCDA methodology associates the Analytic Hierarchy Process (AH...

This paper considers Interval Analytic Hierarchy Process (Interval AHP) in group decision making for encouraging communication. Interval AHP is suitable method to handle subjective judgments since the induced results are intervals which can include uncertainty of given information. The decision makers’ opinions can be aggregated at some stages of decision making process to reach consensus. One ...

The article presents a method for stock selection from the view of investors who contemplate stocks of a new investment. The AHP (Analytic Hierarchy Process) and Grey Relational Analysis are used as two integral parts of the method. By distilling information from the Judgment matrix, the AHP-GRA method provides a framework to assist investors in analyzing various investment factors, evaluating ...

Trains of action potentials in hippocampal pyramidal neurons are followed by a prolonged afterhyperpolarization (AHP) lasting several seconds, which is attributable to the activation of a slow calcium-activated potassium current ((sI)AHP). Here we examine the location of (sI)AHP on CA1 pyramidal neurons by comparing it with two GABAergic inhibitory postsynaptic currents (IPSCs) with known somat...

In the analytic hierarchy process (AHP), a decision maker first gives linguistic pairwise comparisons, then obtains numerical pairwise comparisons by selecting certain numerical scale to quantify them, and finally derives a priority vector from the numerical pairwise comparisons. In particular, the validity of this decision-making tool relies on the choice of numerical scale and the design of p...

The ELECTRE I is one of the most extensively used methods to solve multiple criteria decision making (MCDM) problems. In this paper, we propose a novel AHPbased ELECTRE I method of reliability design scheme decision for computer numerical control (CNC) machine. Based on the AHP method combined with ELECTRE I, the decision model is built to select the optimal design scheme. The AHP method is app...
