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 ...

This approach, which combines between two chronologically successive problems, leads to the use of multi-objective optimization. In fact, we study the multi-objective integrated problem of location ...

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 ...
