    1. Resource Management with RFID Technology in Automatic Warehouse System Guidong Liu 2006.10.12

    2. Current warehouse operation environment Background Production in Enterprises has changed from the traditional mass production into the mass customization production

    3. Problems arising from customization production Pipelining failure Incessantly regulating of storage strategy Frequently examining items stored Loss of productivity

    4. Challenge for the automatic warehouse Increase of throughput rate Enhancement of productivity Reduction of the operation cost

    5. Technology requirements Quickly finding out the target stored items Quickly positioning the storage locations for load items Quickly positioning the material handling equipment Formulating optimal strategy for load items storing/retrieving

    6. Research of item identifying and equipment positioning in current warehouse Item identifying Barcode Advantages convenient , cheap Disadvantage short range reading ability

    7. Equipment positioning Active RFID system Advantage Positioning of material handling equipments Disadvantage Signals are vulnerable hampered by the metal warehouse structure Principle of positioning limits its accuracy

    8. Proposals in this paper Keypoint 1: Employment of two kinds of passive RFID tags to achieve the function of: material handling equipment positioning target load item identifying.

    9. Keypoint 2: Formulation of optimal strategies both for load item storage/retrieval and for the operation arrangement of material handling equipments with load item identity information as well as the position and operation process information of the material handling equipments.

    10. Brief introduction of RFID technology RFID is a technology concept that refers to the use of radio waves to identify objects

    11. Application cases: RFID technology in Kitchens, Inc. RFID technology in Gillette

    12. Application mode proposed Warehouse resource Storage locations Making good use of storage locations can greatly enhance throughput and reduce operation costs. Material handling equipments Mainly including of crane robots and shuttle robot. Each robot is fixed with two RFID readers on the bottom of and on the top of it.

    13. Warehouse server Collection of information of load item and material handling equipments Formulation of optimal strategies for load item storage/retrieval and operation of material handling equipments

    14. RFID system Each robot is fixed with two RFID readers on the bottom of and on the top of it. Many passive RFID tags are pasted on the aisle with respect to each rack column. The code stored in each tag is corresponding to a record in a database of a warehouse server. RFID tags on the load items record the load item’s identity information.
