How to Use RFID to Manage yard Workflow?


At manufacturing facility in , the company is deploying a system provided  to track the locations of trailers filled with material, and to expedite the unloading of their contents.


installing a passive RFID and GPS system to track the locations and movements of trailers in the yard of manufacturing facility. 


manage freight movement around the facility yard, thus ensuring that the average 100 trailers arriving daily, filled with materials for the products the firm makes, can be located and unloaded at the appropriate time.


The challenge related to manual tracking of trailers is time. After trailers arrive and are manually checked in by a gate guard, they are often parked somewhere in the yard—which includes 250 trailer parking spaces and 30 dock doors. As such, the warehouse managers often do not know when or if a particular trailer has arrived until several hours or a day later, and employees may need to drive around the site in order to locate it. Valuable time can be lost if the material needed can not be accessed immediately. In addition, a trailer's owner may charge the manufacturer a retention fee for the time that trailer sits in the yard. Manufacturers—or their third-party-logistics providers—typically track the locations of trailers and the freight they contain with spreadsheets alone. 



Once the system is in place, a fixed  reader installed at the gate will capture the UHF Gen 2 RFID tag ID number on a tag attached to the trailer. In the case of dedicated trailers, which continually come from the same supplier and carry the same supplies, a tag will be permanently attached to the trailer. For other suppliers delivering for the first time, or that deliver in a multitude of trailers, a tag will be supplied to the driver when he enters, and the gate guard will input data about the shipment into the software system management database
