Some Interactive and Hybrid Methods and Applications of
Multiobjective Optimization
Many methods have been developed for multiobjective optimization.
Typically, they aim at supporting a decision maker in finding the
best compromise solution where several conflicting criteria are
optimized at the same time. Because the compromise solutions,
so-called Pareto optima, cannot be ordered without additional
information, the solution process requires preference information
from a decision maker in some for or another. In this talk, some
new interactive and hybrid methods are introduced. In interactive
methods, a solution patterns is formed and repeated several times,
and in each iteration further information about the decision
maker's preferences is inquired. In this way, the decision maker
can learn about the nature of the problem and about the
interdependencies among the criteria involved. (S)he can also
adjust one's preferences while learning and concentrate on such
solutions that seem most promising. On the other hand, hybrid
methods combine elements of different methods in order to benefit
from their strengths and overcome their weaknesses. An example of
new interactive methods is NAUTILUS which starts from the worst
possible objective values and proceeds towards the most preferred
Pareto optimal solution without the need of trading off between
the objectives. Other methods to be introduced include Pareto
Navigator and NIMBUS. Finally, some applications are summarized
and some experiences with them are discussed.
