Abstract: A system and method configured for determining optimal mail sorting of a mailing is disclosed. The method may comprise determining a number of mail pieces to be sent in the mailing, selecting an initial scheme for sorting the mailing based on the number of mail pieces, and simulating a mail sorting based on the initial scheme and obtaining efficiency statistics of the simulated mail sorting. After the selected initial scheme is simulated, the method may further comprise generating an updated scheme, in response to the efficiency statistics being less than optimal, by revising the initial scheme. The method includes simulating a mail sorting based on the updated scheme, revising and simulating schemes until efficiency statistics are optimal. The initial scheme may be based on historical schemes for mailings of similar number of mail pieces, selected by an operator from historical schemes for mailings, or a customized scheme for the mailing.
