The paper concerns the pairwise comparison method used to rank a finite, usually small number of alternatives, in the Analytic Hierarchy Process (AHP), which belongs to a certain class of multiple attribute decision making methods. Ranking of alternatives is calculated based on expert judgments expressing relative importance for each pair of alternatives. From mathematical point of view calcula...

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...

The Analytic Hierarchy Process (AHP) method was introduced to help the decision maker to express judgments on alternatives over a number of criteria. In this paper, our proposal extends the AHP method to an uncertain environment, where the uncertainty is represented through the Transferable Belief Model (TBM), one interpretation of the belief function theory. In fact, we suggest a novel framewo...

Here, we propose a fuzzy analytic hierarchy process (FAHP) method to evaluate the alternatives of enterprise resource planning (ERP) system. The fuzzy AHP approach allows the users get values more accurately to model the vagueness which changes according subjective ideas in the decision-making environment for ERP system selection problem. Therefore, fuzzy AHP method is used to obtain firm decis...

Using case studies, this paper describes how clinical engineers and healthcare CIOs, CTOs, and IT/IS specialists can use the Analytic Hierarchy Process (AHP) to improve the quality of diverse and important decisions that hospitals face today. AHP is a versatile and proven decision support tool that allows the user to design a hierarchical structure for decision-making and weighs the trade-offs ...

The selection of a project among a set of possible alternatives is a difficult task decision makers have to face. Difficulties in selecting a project arise because of the different goals involved and because of the large number of attributes to consider. Our approach is based upon a fuzzy extension of the Analytic Hierarchy Process (AHP). This paper focuses on the constraints that have to be co...

Analytic Hierarchy Process (AHP and ANP) has provided an efficient ways for people to rank the priority of criteria and alternatives in terms of numerical ordering. More importantly, it has been greatly accepted by exponentially increasing number of scholars and practitioners. This phenomenon has not occurred in traditional utility theory. Utilizing the concepts of habitual domains, we will try...

The Analytic Hierarchy Process AHP is a theory of measurement. Reference to this paper should be made as follows: Saaty, T.L. Decision.The Analytic Hierarchy Process AHP is due to Saaty 1980 and is often referred to, eponymously, as the Saaty method. It is popular and widely used.The Saatys method dealt with consistency of the pairwise comparison matrix. A consistent matrix mean e.g. if the dec...
