Abstract
Systems and methods for the removal of expiring items from inventory are disclosed. In some embodiments, a method includes determining a breakeven holding time for an inventory item and calculating, based at least in part on a demand forecast for the inventory item and on the breakeven holding time, a first quantity of the inventory item to be removed from the inventory. The method also includes identifying an expiration time corresponding to the given inventory item and, in response to the expiration time being shorter than the breakeven holding time, calculating a second quantity of the inventory item, where a difference between the second and first quantities represents an additional quantity of the inventory item to be removed from the inventory. The method further includes causing at least one portion of the additional quantity of the inventory item to be removed from the inventory according to an inventory removal function.
