$7\mathrm{.}22$ Consider three items with the following profiles:

Item Annual Demand Annual Requests Unit Cube

A $100$ units $25$ requests $1$ ft$3$

B $50$ units $5$ requests $0\mathrm{.}5$ ft$3$

C $200$ units $16$ requests $2$ ft$3$

a$.$ What is the total demand in cube for items A$,$ B$,$ and C$?$

b$.$ If $20$ ft$3$

of space is allocated for item C$,$ how many times will the item be replen$-$

ished in one year?

c$.$ If each item is to receive a location in the forward area and an equal$-$time$-$supply al$-$

location policy is used, how much space will be allocated for each item assuring a

one$-$week time supply $($assume $50$ weeks$)?$

d$.$ If the items are to be assigned locations in the forward area on the basis of popular$-$

ity storage, and they are allocated space as in part c$,$ rank the items so as to maxi$-$

mize the number of picks in the most accessible storage space.
