Hello

i was wonder if it is possible to make a multiple objectives in the ILOG OPL?

i mean something like that :

minimize sum(capa in Components) (Capacitycapa);
minimize Capacity13;

thanks?

Hi

Unfortunately, there is no multi objective in OPL. To deal with multiple objective, e.g. hierarchical objective, the best way is iterating model solving by upgrading the models and objective for each term as well as reusing previous solution as starting point.
