handling the one or more items to be subjected to exception handling using a predefined exception handling method;

identifying a layer of the pallet in which each of the plurality of items can be loaded based on the acquired information;

determining a loading class of each of the plurality of items based on the identified pallet layer; and

classifying the plurality of items into one or more pallet-based item groups based on the determined loading class of each of the plurality of items.

3. The guide providing method of claim 2, wherein the handling the one or more items to be subjected to exception handling comprises, when a first item has a bundle attached thereto, classifying the first item and the bundle into a single sub-group, and

the classifying the plurality of items into the one or more pallet-based item groups comprises classifying the first item and the bundle into a common pallet-based item group.

4. The guide providing method of claim 2, wherein the handling the one or more items to be subjected to exception handling comprises, when a first item has dimensions that do not up to predefined critical dimensions, classifying the first item into a small-cargo item group to be excluded from pallet loading.

5. The guide providing method of claim 2, wherein the handling the one or more items to be subjected to exception handling comprises, when a cost value of a first item exceeds a predefined critical cost value, classifying the first item into a double-packing item group;

and

the determining the loading class of each of the items comprises determining a first item loading class based on item dimensions information and item constraint information of the first item in a double-packed state.

6. The guide providing method of claim 2, wherein the handling the one or more items to be subjected to exception handling comprises, when a first item of the plurality of items and a second item of the plurality of items have a common stock keeping unit (SKU), classifying the first item and the second item into a single sub-item group;

and

the classifying the items into the one or more pallet-based item groups comprises classifying the first item and the second item into a common pallet-based item group.

7. The guide providing method of claim 2, wherein the classifying the items into the one or more pallet-based item groups comprises classifying items determined to be of a first loading class such that the corresponding items can be evenly distributed between the item groups.

8. The guide providing method of claim 2, wherein the classifying the items into the one or more pallet-based item groups comprises classifying the plurality of items such that a sum of weights of items included in a first item group is equal to a sum of weights of items included in a second item group.

9. The guide providing method of claim 1, wherein the matching each of the plurality of item groups with the corresponding pallet comprises:

selecting a first pallet of the plurality of pallets having a smallest area based on the pallet dimensions information;

determining whether all items included in a first item group can be loaded together on the first pallet; and

selecting a second pallet having a larger area than the first pallet when not all the items included in the first item group can be loaded together on the first pallet.

10. The guide providing method of claim 1, wherein the performing the simulated loading of each of the plurality of items comprises dividing a first layer of the matched pallet into a plurality of blocks and performing a simulated loading of items included in the first item group in the first layer while changing a direction in which the corresponding items are arranged for every block of the first layer.

11. The guide providing method of claim 1, wherein the performing the simulated loading of each of the plurality of items comprises performing a simulated loading of items included in a first item group on the matched pallet such that a center of gravity of the corresponding pallet with items loaded thereon is lowered.

12. The guide providing method of claim 11, wherein the performing the simulated loading of the items included in the first item group comprises loading each of the plurality of items included in the first item group such that an angle between a first side of a first item included in the first item group and a first side of a pallet that contacts the first side of the first item is reduced.

13. The guide providing method of claim 1, wherein the performing the simulated loading of each of the plurality of items comprises performing a simulated loading of the items on a first pallet and a second pallet such that a height to which the items can be loaded on the first pallet is equal to a height to which the items can be loaded on the second pallet.

14. The guide providing method of claim 1, wherein the determining the loading sequence and arrangement for loading the plurality of items included in each of the item groups on the matched pallet comprises:

calculating a score of each simulated loading result performed by changing loading sequences and arrangements based on a number and area of pallets used to load the items;

selecting a simulated loading method based on the calculated score of each simulated loading result; and

determining the loading sequence and arrangement for loading the plurality of items included in each of the item groups on the matched pallet.

15. A guide providing method comprising:
