In a production facility there is an area $(40$ m x $25$ m$,$ max height $=8$ m$)$ where you have to design

a warehouse and a material handling system based on trucks. The unit loads are euro pallets

$($height $=1,2$ m$).$ Design the warehouse $($I$/$O point, number of aisles, overall storage capacity etc.$)$

and calculate the number of trucks needed for getting a MH capacity not less than $200$ UL$/$h

$($single command cycles$),$ assuming for the trucks the following data:

$$ Horizontal speed $($for carrying$)$: $2,5$ m$/$s

$$ Vertical speed $($for loading$/$unloading$)$: $0,5$ m$/$s

$$ Time for each turn: $1,5$ s

$$ Other fixed times $($per each
