A fabrication cell at Spradley’s Sprockets uses the pull method to supply gears to an assembly line. George Jitson is in charge of the assembly line, which requires 500 gears per day. Containers typically wait 020 day in the fabrication cell. Each container holds 20 gears, and one container requires 1.8 days in machine time. Setup times are negligible. If the police variable for unforeseen contingencies is set at 5 percent, how many containers should Jitson authorize for the gear replenishment system?
