The warehouse from the previous problem has decided to change its functional flow network in order to possibly decrease the amount of workers needed.

Consider the following parameters to determine the number of workers needed:

-Each shift is 7.5 hours

-No personnel sharing between departments

-1500 cases are received per day and palletized to be stored in the Reserve Area

-In addition, 250 pallets (10 cases per pallet) are received per day and palletized to be stored in the Reserve Area

-Top 20% of SKUs (accounts for 80% of all cases) assigned to bottom level of racks

-Remaining 80% of SKUs (accounts for 20% of all cases) stay in the rest of the Reserve Area (upper levels of racks)

-Pallet put away rate (from receiving to reserve) = 15 per hour

-Case picking rate from the bottom level of racks = 1000 per hour

-Pallet picking rate from the reserve area (for either replenishing the bottom level or shipping) = 5 per hour
