*Location of a semiobnoxious
facility: a biobjective approach*

**
E. Carrizosa, E. Conde, ****D. Romero Morales**

In the location of a semiobnoxious facility one has to consider both transportation and environmental (or social) costs to be optimized. Such objectives are modeled as functions of the distances to a set of demand points, leading to a biobjective optimization problem. Since the usual solution set is in general infinite and so of dubious interest to Decision Makers, we propose as solution a finite feasible set representing the best compromise solutions. Such a finite set is obtained, using the concept of a-dominance, by a standard Global Optimization technique.
