The literature on discrete facility location often assumes all costs to be linear. In practice, however, it is likely that parts of the cost are non-linear. Convex throughput cost arise, e.g., in facility location models with congestion if customer waiting times are penalized in the objective function. Moreover, economies of scale

often occur in transportation and give raise to concave transportation cost functions. For both types of non-linearities, this paper investigates a Lagrangean

relaxation approach to a multi-type capacitated facility location problem that yields a non-linear knapsack problem as a part of the Lagrangean subproblem.
