Amazon pilots FFLB to reshuffle warehouse workers every three minutes and target $193 million in annual labor savings

Amazon is piloting a “Full Facility Load Balancing” (FFLB) system in robot-enabled warehouses that dynamically reassigns workers about every three minutes. Internal estimates put the potential impact at nearly 7 million fewer labor hours a year and about $193 million in annual labor-cost savings. The approach concentrates on the Container Build function and has been deployed at dozens of North American automated sites, with plans to expand to all ARS facilities within the year. Amazon said the savings figures are based on hypothetical modeling rather than measured productivity outcomes.
