A Model Proposal for Wall Material Selection Decisions by Using Analytic Hierarchy Process (AHP)

Analytical hierarchy process, developed by Saaty, is a multi-criteria decision making method. It creates a hierarchy using the goal, decision criteria and decision alternatives, and sorts the various alternatives according to their relative importance. The aim in AHP is to choose the most suitable and important alternative, by making an arrangement from the most important to the least. In this study, a real life material selection application in a hotel building is described by using AHP method. Wall materials such as brick blocks, pumice concrete block, sand autoclaved aerated concrete blocks are decision alternatives and mechanical properties, physical properties, ease of application and costs of these materials are the decision factors. The analysis was performed based on the opinion of an expert and the most suitable alternative is selected. Also, it is concluded that the order related to the alternatives is reliable for the decision markers. Thus, a decision supporting method for a construction company using AHP applications is developed.
