Assume the following layout. Each number represents the amount of weekly loads going to each department. D 115 5 B 10 10 5 50 00 5 C 15 5 E 15 If it costs 1$ per load for moving between adjacent departments and 2$ per load between non- adjacent 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)
