Fuzzy analytical hierarchy process

Especially for business life, it?s very hard and important to make right and good decisions andbe succesfull, because there are a lot of difficulties of life and choices. Human moves with hissense at decision period but sometimes there can be very complex situations that we can?tknow how to compare which of these criteria and candidates with others. At that time we haveto reduce the problem into little parts to see it easly. Then now, after these reduction we cancompare all these little parts, (criteria, candidates) one by one with others under our maingoal. It is convenient to use Saaty?s Analytical Hierarchy Process approach in thesecomparement. Since decision makers need to express uncertainty with fuzzy numbers insteadof real numbers, this approach extended to fuzzy environment. Thus we can analyse thisimportant decision more detailed.In this project under Fuzzy Analytical Hierarchy Process subject, there are six methodsstudied. Fuzziness, fuzzy operators, fuzzy sets and properties, detailed desciriptions of studiedmethods are subjects of this project. Also the advantages and disadvantages of these methodsare judged. Finally there is a program written in Java for Enea and Piazza?s I. method.Keywords: Decision making, analytical hierarchy process, fuzzy analytical hierarchy process,multi-criteria decision making, multi-objective decision making.vii
