Second, the conversion to a single-objective optimization problem involves additional constraints. Third, since most real-world goal programming problems involve nonlinear criterion functions, the ...

The following sections discuss the basic ideas of problem formulation using multi-objective optimization paradigm. 5 A Multi-Objective Genetic Algorithm In order to deal with the multi-objective ...

Three distinct multi-item lot-sizing instances are then presented to demonstrate the approach, and comparative computational results are presented. Finally, we also use the classification to point out ...
