Abstract

Operation of a supply chain having a number of workstation that process items supported by pallets is managed using a sub-central controller, a number of pallet devices, each associated with a pallet, and one or more workstation devices, each associated with a workstation. A workstation device is operable to communicate with the pallet devices to acquire pallet information and to process the pallet information based upon rules provided by the sub-central controller. The workstation device acts on the processed pallet information to modify the operation of the supply chain. A central controller may be used to coordinate activities of multiple sub-central controllers.

6. A method in accordance with claim 5, further comprising the sub-central controller modifying operation of the supply chain dependent upon information from the at least one database and dependent upon information received from at least one workstation device of the plurality of workstation devices.

7. A method in accordance with claim 1, further comprising a pallet device of the plurality of pallet devices obtaining the pallet information by communicating with a pallet sensor to acquire pallet load information, wherein the pallet sensor is at least one sensor selected from the group of sensors consisting of weight, physical location, temperature, pressure and chemical presence sensors.

8. A method in accordance with claim 1, wherein the supply chain further comprises a central controller operable to communicate with a plurality of sub-central controllers, the method further comprising:

the central controller processing information from a plurality of sub-central controllers dependent upon a set of rules to generate processed sub-central information; and

modifying the operation of the supply chain dependent upon the processed sub-central information.

9. A method in accordance with claim 1, wherein the workstation device, of the plurality of workstation devices, communicating with the pallet devices to acquire pallet information utilizes a wireless communication link.

10. A method in accordance with claim 1, wherein the workstation device acting on the processed pallet information to modify the operation of the supply chain comprises the workstation device alerting an operator of a workstation.

11. A method in accordance with claim 1, wherein the pallet comprises a transport structure select from the group of transport structures consisting of a shipping pallet, a tote, a buffer, a cart, a crate and a box.

12. A method in accordance with claim 1, further comprising:

a workstation device, of the plurality of workstation devices, communicating with a communication device of an operator stationed at the workstation to determine the number and identity of operators at the workstation;
