Abstract: According to one aspect of an embodiment a calculation device includes a determination unit that determines whether each of the pieces of the attribute information matches each of the conditions. The calculation device includes a decision unit that decides, on the basis of whether the continuous values included in the index information that is associated with the condition determined to be matched with the attribute information continue up to the predetermined value, whether the predetermined information is specified as the distribution target. The calculation device includes a calculation unit that calculates by using the coefficient that is included in the index information and that is associated with the condition that is determined to be matched with the attribute information, a priority at the time of distribution of the predetermined information.
