This paper provides an integrated model of radio-frequency identification (RFID) and four-dimensional Computer-Aided Design (4D CAD) in construction management. RFID involves the use of tags that collect data and transmit data. RFID can collect data by radio waves instead of light waves. RFID technology is surpassing barcode technology where light waves are easily blocked and barcode labels are easy to fall off or become unreadable due to dust, dirt, or other contaminants. 4D CAD which involves 3D construction models and construction schedules presents visualized construction process. Integration of RFID and 4D CAD in this paper built a dynamic construction management and control system which would reduce the time of capturing data on site and control quality of construction materials efficiently. Pilot test result shows that a construction manager can easily understand how and what a complicated construction project will be accomplished. Although further analysis is necessary, RFID and 4D CAD show promises of being a beneficial technology in construction management.

The system consists of ability to apply multiple machines to perform the same operation on a part, as well as system ability to absorb large scale changes, such as capacity and volume. In order to improve the structure of the Flexible Manufacturing System ,Programmable Logical Controller(PLC) is used at control processing center, a card reader with recognition RFID is used for Detection device, an Automatic Guided vehicle (AGV) is used for Transportation purpose ,and computer network system is applied in Information management and control device. The application of an AGV in Automation Industries has broadened during the late 20th century; this is due to competitive in the worldwide economy, manufacturing operations has to react quickly for meeting clients demand while increasing competitiveness with regard to their own production costs. AGV is a mobile robot that ...
