When taking a new order, a Northway employee inputs data about that order, scans a new
RF Identics EPC Gen 2 tag and affixes it to a folder—or, in the case of a smaller order, to a paper document. The process links the tag's unique
Electronic Product Code (EPC) number with data about the order. From that point onward, the tagged folder or document is placed at a workstation unit (a wooden cabinet with a white board on which paperwork can be placed to be more readily viewable by production employees).
Thus far, two
RFID-enabled workstations units are in operation, though the company plans to have 11 workstation readers in use in January, each representing one stage of production. When an employee at one workstation finishes the assigned tasks for a particular work-in-progress, that person moves the folder to the next RFID-enabled workstation, where a motion
sensor detects the worker's presence and triggers the RFID reader to wake up. Materials involved in the building process are then moved to the next workstation as well.
The
reader captures ID numbers from up to 50 folders placed within 2 to 3 feet of its location. Managers can refresh the system from their PCs, alerting the interrogators to capture and send
RFID tag IDs at any given time. In either case, those ID numbers are transmitted to a back-end system via a cabled connection with Atlas RFID Solutions software, which translates that data for use in Northway's
manufacturing execution system (MES). The system is designed to send an alert to the managers' PCs if a folder spends too many days at a specific station, or if it is removed from one station without being returned to another within a predetermined acceptable amount of time.
According to Brown, the RFID-enabled workstations should help streamline operations for Northway. Eventually, he says, the company intends to direct the RFID-acquired data to its Web site, where customers can go online, input their order ID numbers and view for themselves the location of the specific order.
"We will also work to implement advanced information gathering, such as personnel through-put analysis," says O'Hora, who describes the system as the result of teamwork between Northway and Atlas RFID Solutions. "Atlas listened to our needs and concerns, and they were willing to think innovatively."
