In the future, we will work on improving RFID readability on metal
products to make the proposed system more reliable. Besides, the sys-
tem will be extended to suppliers so that it can cover the mechanical
contractor's supply chain. Finally, we will add analysis tools to make
predictions for better inventory management and supplier performance
evaluation and to support collaborative production planning and con-
trol methods (e.g. Last Planner System) based on the tracking data col-
lected and deposited in the cloud. The long-term goal is to enable firms
to build supply market intelligence databases that will guide supply
chain decisions in the construction industry.
