ABSTRACT

In this study, the multi - criteria decision making methods of fuzzy logic, fuzzy AHP and fuzzy TOPSIS were utilized to determine the ideal class of ships that a specific shipyard can build during the decision making stages of shipyards for them to be successful in the competitive environment of the world market. For this purpose, a general information and related literature are reported in the first chapter. Decision making, decision-making methods, fuzzy logic, fuzzy decision methods and the data obtained by implementation are presented consecutively in the chapters that follow. In the last section, general results and evaluations obtained from the study are given.

With the ever-evolving customer demands and differentiated ship types due to the development of technology and the importance given to the project management by shipbuilding companies, which are in an effort to maintain their place in the world shipbuilding market, is increasing. It is suggested that the companies, which would like to take the lead in project management within the shipbuilding sector, should adopt the decision-making and multi-criteria decision making methods examined in this study and use these methods in every decision stage. The appropriate method will be integrated into every decision-making process and contributes to the improvement of processes and decisions.
