The technology has a wide range of application in not only the monitoring of logistics transportation, but also in integration of manufacturing processes.
This study focuses on the possibility and benefits of applying the RFID technology to process reengineering for dental laboratories, where dental impressions and artificial teeth are manufactured according to order from dentists.
This study first reviews the operational processes from user’s perspectives and analyzes the mutual effects between order management, production of dental impressions and artificial teeth, and distribution of the manufactured objects, i.e. the dental impression and the artificial teeth shipped to the dentist clinic. . The Rational Unified Process (RUP) is the formal methodology conducted in this stage. Next, Unified Modeling Language (UML) , a common approach to information systems analysis and design, is adopted to devise reengineered processes using RFID tags and equipment. The result of this UML step provides a basis for prototyping an information system with the capability of object identification automation using RFID.
This study further accumulates data on manufacturing and distribution times for some selected steps after the new system was implemented. The time used in recording a dental impression manufactured according to an order was reduced 97 %, while the time used in preparation for shipping to the dentist clinic is reduced 87 %. In the aspect of order receiving and recording, the improvement on time efficiency is less significant.
In summary, this study describes an example that demonstrates the use of RFID in object identification automation for dental laboratories; as a result, the burdens on workforce and human-induced errors are also substantially reduced.
