Abstract

A method of assigning electronic price labels (EPLs) to groups of price look-up file items which is based upon the price change frequencies of the items in the groups. The items are divided into a plurality of groups. Price change frequencies for items within each group are determined. A minimum price change frequency for each group is determined. In a first embodiment, EPLs are assigned to items in any one of the groups only if a predetermined number of the price change frequencies in the one group exceed a predetermined minimum price change frequency for the one group. In a second embodiment, the groups are ranked starting with a first group having a highest number of items that exceed the minimum price change frequency for the first group and ending with a second group having a lowest number of items that exceed the minimum price change frequency for the second group, and EPLs are assigned to a plurality of items less than the totality of items by order of rank of the groups, beginning with the items in the first group, until the plurality of EPLs are exhausted.

Claims

1. A method of automatically assigning electronic price labels to items within a group utilizing a computer system, the method comprising the steps of:

determining price change frequencies for items within the group utilizing the computer system;

assigning electronic price labels to the items within the group utilizing the computer system only if a predetermined number of the price change frequencies exceed a predetermined minimum price change frequency for the group.

4. The method of any one of claims 1-3 wherein each of said items has a corresponding price look up file entry stored in a memory, and the method further comprises the steps of:

analyzing price change information for each of said items for a predetermined period of time utilizing the computer system; and

producing a sorted list of said items in order of price change frequency.

5. The method of any one of claims 1-3 further comprising the step of:

generating a report of the assignments of the electronic price labels to the items within the group.

6. The method of any one of claims 1-3 further comprising the step of:

identifying items which occur multiple times in a price look up file listing the items.

7. The method of any one of the claims 1-3 further comprising the step of:

printing overlays for the electronic price labels utilizing an overlay printing system after electronic price labels are assigned to the items.

8. The method of claim 1 further comprising the step of:

sorting the items into identified groups before said step of determining.

9. The method of claim 8 further comprising the step of:

accumulating the number of price changes for the items over a predetermined period of time.

11. The method of any one of claims 1-3 further comprising the step of:

producing a recommendation that an electronic price label be removed from one item where the computer system has determined that the electronic price label can be better utilized in conjunction with another item.

2. A method of automatically assigning electronic price labels to items utilizing a computer system, the method comprising the steps of:

dividing the items into a plurality of groups;

determining price change frequencies for items within each group;

determining a minimum price change frequency for each group; and

assigning electronic price labels to items in any one of the groups only if a predetermined number of the price change frequencies in the one group exceed a predetermined minimum price change frequency for the one group.

10. The method of claim 2 further comprising the step of:

ranking the plurality of groups by average price change frequency.

3. A method of automatically assigning a predetermined number of electronic price labels to a plurality of items less than a totality of items utilizing a computer system, the method comprising the steps of:

dividing the totality of items into a plurality of groups;

determining price change frequencies for items within each group;

determining a minimum price change frequency for the items in each group;

determining a number of items in each group that exceed the minimum price change frequency for the group;

ranking the groups starting with a first group having a highest number of items that exceed the minimum price change frequency for the first group and ending with a second group having a lowest number of items that exceed the minimum price change frequency for the second group; and

assigning electronic price labels to the plurality of items by order of rank of the groups, beginning with the items in the first group, until the plurality of electronic price labels are exhausted.

12. An electronic price label system for automatically assigning a plurality of electronic price labels to a plurality of items comprising:

a memory storing a price look up file including price information for said plurality of items;

a computer operably connected to the price look up file, said computer being operable to divide the plurality of items into groups, to determine price change frequencies for the plurality of items, and to assign the plurality of electronic price labels to individual ones of said plurality of items only if a predetermined number of the price change frequencies for items in a group exceed a predetermined minimum price change frequency for the group.

13. The electronic price label system of claim 12 further comprising a report generator for generating a report listing the assignments of electronic price labels to individual ones of said plurality of items.

14. The electronic price label system of claim 12 further comprising a mapping of items stored in the memory and wherein the computer system is further operable to determine the location of multiple occurrence items corresponding to the same entry in a price look up file utilizing said mapping.
