20 years have gone by since the first complex Revenue Management System DINAMO (Dynamic Allocation and Maintenance Optimizer) has been applied for an integrated price and capacity control. From then on Revenue Management has established itself as a planning- or rather as a decision-instrument for acceptance/rejection problems mainly within the service industry. Airlines, car rentals and hotels particularly use this instrument. Until today only a few authors have discussed the possibility to assign Revenue Management also to the industry [1 - 4].
