ON THE SELECTION OF SHIP WASTEWATER TREATMENT PLANT INCORPORATING ANALYTICAL HIERARCHY PROCESS WITH 0-1 GOAL PROGRAMMING

As a result of the continuous pollution of the air, seas and soil, the deterioration of the natural equilibrium can be felt severely. Therefore, the prevailing vision of sustainable environment is frequently mentioned in the international arena. There are many industrial sources of pollution. Each of them significantly affects the environment. In the seas, the biggest source of pollution is the ships. Pollutants originating from ships are solid pollutants, bilge water, ballast water, anti-fouling system, etc. Another important source of pollution is wastewater. Untreated wastewater discharged to the sea will cause the natural balance to deteriorate. Therefore, wastewater treatment equipment is needed. The integration of equipment in ship design is a challenging process and many criteria must be considered together. In this study, it is stated that the criteria of the ship wastewater system will be evaluated and a set of alternatives is determined by Analytical Hierarchy Process (AHP). In addition, in accordance with a scenario created by considering the integration constraints of these systems into the ship, a hybrid model in which the 0-1 Goal Programming and AHP weights are applied, and the optimum solution (equipment) is selected which satisfies the determined constraints
