Abstract

An operational process for product distribution includes grouping product into groups when the product is in a first sort level and sorting the groups of product, in a first pass operation, to a second level sort. The method further includes sequencing the second level sort product including late arriving product, in a second pass operation, into a sequence of product. A machine readable code can also be used to implement the functionality of the operational process.

Claims

1. A system for processing mail pieces simultaneously on at least two machines, each of the machines having bin partitions allocated for operations, comprising:

in a first machine,

processing simultaneously, in a first time period, in respective allocated partitions;

(i) incoming group and outgoing primary sorting operations;

(ii) outgoing primary sorting operations; and

(iii) outgoing carrier group holdout mail pieces;

processing simultaneously, in a second time period, a delivery point sequencing operation; and

processing simultaneously, in a third time period, a residual sorting operation for late arriving mail items which were not processed in the first or second time period; and

in a second machine, processing simultaneously, in the first time period, outgoing Group Sort operations; and

processing simultaneously, in the second time period and the third time period, a delivery point sequencing operation.

2. The system of claim 1, wherein the first and second machine each have 360 bins, represented by four equally divided partitions 1 through 4, each having 90 bins.

3. The system of claim 1, wherein:

approximately eight bins are reserved for the incoming Group Sort operations;

approximately 148 to 262 bins are reserved for outgoing primary sorting operations;

any of the bins are reserved for the residual sorting operation for late arriving mail items; and

approximately 352 to 360 bins are reserved for the delivery point sequencing operation.

4. The system of claim 1, wherein the first and second machine each have N bins, represented by four equally divided partitions.

5. The system of claim 1, wherein:

approximately N bins are reserved for the incoming Group Sort operations;

approximately N₁ bins are reserved for outgoing primary sorting operations;

any of the bins are reserved for the residual sorting operation for late arriving mail items; and

approximately N₂ bins are reserved for the delivery point sequencing operation.

6. A machine readable medium containing code for processing mail pieces simultaneously on at least two machines, each of the machines having bin partitions allocated for operations, comprising at least one module to provide function to:

in a first machine,

processing simultaneously, in a first time period, in respective allocated partitions;

(iv) incoming group and outgoing primary sorting operations;

(v) outgoing primary sorting operations; and

(vi) outgoing carrier group holdout mail pieces;

processing simultaneously, in a second time period, a delivery point sequencing operation; and

processing simultaneously, in a third time period, a residual sorting operation for late arriving mail items which were not processed in the first or second time period; and

in a second machine, processing simultaneously, in the first time period, outgoing Group Sort operations; and

processing simultaneously, in the second time period and the third time period, a delivery point sequencing operation.
