$1.$ Use a third$-$party cross$-$docking facility in Arizona that charges $$0\mathrm{.}10$ per unit for this cross$-$docking service. This would allow all suppliers to ship product $($destined for all $32$ Arizona stores$)$ using a large truck to the cross$-$dock facility, where it would be cross$-$docked and sent to stores in smaller trucks $($each smaller truck would now contain products from all eight suppliers destined for a single store$).$ Large trucks $($capacity of $40,000$ units$)$ charge $$4,150$ from each supplier to the cross$-$dock facility. Small trucks $($capacity of $10,000$ units$)$ charge $$250$ from the cross$-$dock facility to each retail store in Arizona.
