The customer pulls the car into the proper lane, where an awaiting service technician determines what repairs need to be made and what they will cost, and discusses his findings with the customer. The customer then accepts or rejects the recommendations, and the technician enters all this information into the system under the job number, so that it can be analyzed later by the service center's managers to better understand the types of repair recommendations that are accepted and declined and resolve any customer complaints regarding that technician.
After a plan of action has been made, the customer leaves behind his car, and an employee drives the car to the center's rooftop parking lot, which can hold roughly 300 cars.
RFID readers installed in the parking lot receive the signals transmitted by car's
RFID tag, and based on that data, the system determines where the car is parked, within an accuracy of 3 meters.
When a service technician is ready to begin work on the vehicle, he goes to a computer terminal and opens the job order for the vehicle. The location information for the vehicle is combined with the service center's existing dealership management software, called ADP Autoline. This allows him to retrieve the car quickly, saving valuable time that could otherwise be lost searching for the vehicle. The technician brings the car to the work bay, where a combination of readers and exciters identify the car and the zone in which it is located. After the repairs are finished, a worker moves the car to the carwash station and then back to the parking lot, where it is parked until the customer comes to retrieve it.
"Zones are the virtual areas that the service center is split into. A zone can contain as few as zero or as many bays as practical," said Shibli. "At Al Ghanim, we use WherePorts to create wireless gates into and out of virtual zones. On the rooftop, we use
RTLS to accurately determine the vehicle's location."
When a customer is ready to pick up his vehicle, he must first pay his bill, and then a service center employee locates and retrieves the car based on the information collected via RFID. The employee drives the car to the exit gate. If the invoice is not paid, the arm will not raise, thus preventing the car from passing through the gate. If the system indicates that the invoice was paid, and the arm at the gate raises so the car can leave the service center and be handed over to the customer. Before the customer gets the car, however, the RFID
tag is deregistered from the system and returned to be reused
Shibli said the main benefits of the system are higher customer satisfaction and increased productivity through less wasted time looking for cars. In addition, the service center benefits from greater visibility about the time needed for various processes, such as specific repairs or car washing.
Al Ghanim has been using the system for about one year. Another large facility, the Emirates Motor Company Mercedes Service Center in Abu Dhabi, recently implemented a similar car-tracking system, with the help of TagStone. In addition, TagStone and Zebra recently announced a partnership agreement to provide similar vehicle management systems to other automotive dealerships in the region.
