Abstract

Multiple Criteria Decision Making Methods are used to find optimal solutions to decision problems. These methods allow decision makers to classify the alternatives and sorting them according to the criteria and determine the most suitable alternative. Analytical Hierarchy Process (AHP) is the most important method that enables problems to be modeled in a hierarchical structure. So much so that this method ensures that problems are solved by establishing a hierarchy of purpose, criteria, sub-criteria and alternatives. The logic of the AHP Method is to determine the alternatives to choose from in order to realize the purpose set out and to evaluate the criteria whose weights are determined as a benchmark. However, AHP includes both objective and subjective opinions in the decision process. The difference of AHP Method from other methods is that it decomposes the problem and organizes these components hierarchically. Unlike other methods, AHP includes qualitative factors as well as quantitative factors in to the process. Today, AHP Method is frequently applied especially in the areas of planning, resource allocation, cost/benefit analysis and optimization. It is used in many areas, from performance assesment in the banking sector to selecting the most suitable supplier. In this study, the structure of the Analytical Hierarchy Process Method developed by Professor Thomas L. SAATY have been examined and its advantages compared to other methods have been explained, information about Expert Choice Software Program has been given.
