> I cannot see how adding `fixed_cost` will help to solve your problem, because `existing_capacity * fixed_costs` will always be the same and therefore won't affect the solution. This won't...

> I have that fetish and feel that the objective value should have alls costs in. +1, and it makes the model comparisons easier... Otherwise you have to remove fix-costs...
