Abstract: Systems, methods, and computer program products for managing an auction. A pool comprised of a first plurality of inventory items that are auction eligible is determined from an inventory item network based on inventory controls. A reference index is determined and assigned to each of the first plurality of inventory items in the pool. The first plurality of inventory items are filtered based on at least one inventory item characteristic to define a second plurality of inventory items. The second plurality of inventory items are filtered based on at least one constraint and the reference index associated with each of the second plurality of inventory items to determine an order in which at least some of the second plurality of inventory items are made available for bidding in the auction.

Abstract: Methods, systems, and computer program products for dynamically computing availability for travel inventory items managed by an inventory system. An inventory request is received for a type of travel inventory item managed by the inventory system. One or more types of geographical location data corresponding to the inventory request are determined. At least one of the types of geographical location data is selected to use to compute the availability. At least one geographical inventory control associated with each type of travel inventory item for each geographical location indicated by the selected types of geographical location data is determined. The availability for the inventory request is determined based at least in part on the at least one geographical inventory control determined for each indicated geographical location.
