For this problem, consider that distance between adjacent machines is

$10$ meters and between non$-$adjacent $($transverse $=$ diagonal$)$ is $20$

meters.

a$.$ Develop a From$-$to Chart considering only the flows.

b$.$ Develop the total cost of the layout considering the four layouts given above.Three products are produced on four machines $($A$,$B$,$C$,$D$)$ where each machine requires a $3\mathrm{.}5$ meters area. The routing for each product is given in the following table. Which block layuot minimizes the overall flow x distance $($assume centroid$-$to$-$centroid distances$)/?$
