Suppose that the S$/$R machine travels at a constant speed of $400$fpm and $150$fpm in the horizontal and vertical directions, respectively. Consider a storage rack that is $550$ft long and $95$ft tall. Further suppose that $15$stops are made during each order picking trip.

a$)$ Compute the E$($P$,$ n$,$ D$)$ to complete a trip with $15$ picks

b$)$ Compute the maximum throughput if it takes the picker on average $12$ seconds to pick one or more items from each container and if$,$ between successive picks, the picker spends $2$ minutes at the P$/$D station to discharge the parts picked and to prepare for the next trip
