DOW'S LIST
The Dow Chemical Co.'s RFID/GPD to-do list is diverse. Dow is looking into use of global positioning system (GPS) services for emergency response monitoring of employees who work remotely on a 4,000-mile Dow Gulf Coast pipeline.
The company also has plans to use radio frequency identification (RFID) for "smart shelf" technology for both raw materials and finished goods inventory tracking. RFID readers mounted on plant and warehouse shelves will sense when RFID-tagged items have been added or removed, and automatically debit or add to inventory lists.
Yet another project will be targeted at construction lay-down yards. These are typically large areas the size of football fields where large parts are stored during new chemical production unit construction or maintenance turnaround projects, notes Craig Casto, a member of Dow's RFID/GPS Steering Team. These parts can often be difficult for workers to find. "So we're looking at tagging these large parts with RFID tags, and then using a mesh sensor network to establish a grid over that football field," Casto explains. "That grid would then be constantly monitoring the inventory that's out there, so we could see where the stuff is."
