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 323 gears per day. Containers typically wait day in the fabrication cell. Each container holds ​gears, and one container requires day in machine time. Setup times are negligible. If the policy variable for unforeseen contingencies is set at ​, how many containers should Jitson authorize for the gear replenishment​ system?
