An offshore platform selection approach for the black sea region

This paper identifies and evaluates various offshore platforms which could be feasible for the deep sea operations in the Turkish Black Sea. The aim of this study is to propose a fuzzy based decision making model for selecting an optimum production system by using effective and major criteria at the same time. The model incorporates fuzzy linguistic variables in place of numbers. The conventional methods for production system selection are inadequate for dealing with the imprecise or vague nature of linguistic assessment. To overcome this difficulty, a fuzzy based multi-criteria decision-making method is proposed. Proposed approach is based on the combination of fuzzy analytic hierarchy process (FAHP) and the fuzzy TOPSIS methods. The application could be interpreted as demonstrating the effectiveness and feasibility of the proposed model.
