Abstract: In the present invention a sorting machine in a distribution order is made to process a substantially higher number of distribution order points, within a sorting process, than necessary for sorting in one or several real distribution orders based on the available pigeon holes. Real distribution order points with large quantities of mailing pieces are distributed between several virtual distribution order points with a minimum quantity of mailing pieces. The quantity of mailing pieces statistically determined for each real distribution order point of a defined distribution order are distributed between the virtual distribution order points, as regularly as possible, for the sorting passes preceding the final sorting pass. Then, the sorting passes preceding the final sorting pass are executed. The final sorting pass is thus executed, such that the mailing pieces of a distribution order are sorted into adjacent pigeon holes.

Abstract: The present invention relies on the fact that a sorting machine in distribution order can process a substantially higher number of distribution order points within a sorting process, than necessary for sorting in one or several real distribution orders, based on the available pigeon holes. Real distribution order points with large quantities of mailing pieces are distributed between several virtual distribution order points with as small as possible quantities of mailing pieces. The quantities of mailing pieces statistically determined for each real distribution order point of a defined distribution order are distributed between the virtual distribution order points, as regularly as possible, for the sorting passes preceding the final sorting pass. Then, the sorting passes preceding the final sorting pass are executed. The final sorting pass is thus executed, such that the mailing pieces of a distribution order are sorted into adjacent pigeon holes.

Abstract: The invention relates to a process for sorting distribution sequences on a despatch sorting machine, in which each despatch is arranged in a distribution sequence according to its read and recognized address code, where sorting takes place in several cycles in accordance with the number and size of the available sorting compartments and the sequence requirements. According to the invention, in order to avoid being faced with full compartments, after the recognition of all the despatches' address codes, with one or more full compartments, one or more compartment combinations for one distribution stop are found by iterative search steps taking account of all the compartments available for sorting and all possible distribution stops, while retaining the predetermined despatch sequence, where said combinations are formed by characteristic numbers of the compartments during the passages and which are capable of accepting despatches for distribution at the distribution stop concerned.
