Çok amaçlı karar verme problemlerine etkileşimli bir yaklaşım

In this study, SEMOPS approach, which is an interactive method for solving multiobjective decision making problems, is examined. Water quality management of a river is chosen as an exemplary problem since it has several decision variables, objectives and constraints which are generally nonlinear, and solved interactively by using SEMOPS method. In order to use the known SEMOPS algorithm, a MATLAB based computer program has been developed. And a graphical user interface has also been created to evaluate the results and give the selections which are necessary for the next cycle back to the program properly. The optimum results generated through the program according to defined objectives and constraints for the problem are evaluated by the decision maker in each cycle. And for the next cycle, assignment of the aspiration levels as constraints is performed. These cycles continue until the desired aspiration levels for all objectives are achieved. Using this interactive method enables the decision maker both to revise the aspiration levels according to objectives and to reach the desired results step by step in the solution stages of the problem flexibly. With this computer program, the dialog between the decision maker and the analyst has been eliminated and the spending time until reaching the best compromise solution has considerably been short.
