Assume the following layout. Each numbar represents the emaunt of weekyy loads going to each department. If it costs iS per load for moving between adjacent departments and 3$ per load between nonadjacent departments, what would be the weekly cost of moving through the current layout? Is there a way to rearrange such that costs would decrease? If so, how? What would you be your decreased cost after rearranging the layout? (no need to redraw. Just show the math)
