Question $5$:

A warehouse uses automated guided vehicles with the following details: Loading time at the load station $=0\mathrm{.}80$min, unloading time at the unload station $=0\mathrm{.}45$min, vehicle speed $=55\frac{m}{m}in,$ the traffic factor $=0\mathrm{.}65$ and availability $=0\mathrm{.}89.$

$2\mathrm{.}1.$ Determine the travel distances loaded and empty, based on the layout in Figure $1.$

$2\mathrm{.}2.$ Compute the ideal cycle time.

$2\mathrm{.}3.$ Determine the number of vehicles required to make $40$ deliveries$/hr$ considering that the operator efficiency does not apply, $E_w=1\mathrm{.}0.$
