Discount service device and method

Abstract

A discount service method carried out by a discount service device. The method includes: obtaining discount rate information based on changes in variable values of respective discount elements of an object being sold; on the basis of the discount rate information, identifying, for a plurality of sales records of the object being sold, a consumer distribution corresponding to changes in the discount rates of the respective discount elements of the object being sold; and determining a final discount rate for a predetermined consumer of the object being sold, by applying weights to the respective discount elements, calculated on the basis of the identified consumer distribution. When the consumer distribution changes, the weights of the respective discount elements change, and thus the final discount rate is determined differently, even when the variable values of the respective discount elements for the predetermined consumer are the same.
