Baker Machine (see Problem 3) is considering two alternative layouts. Compare the wd scores using rectilinear distance of the following two block plans to determine which alternative layout is better.

Problem 3, Baker Machine Company is a job shop that specializes in precision parts for firms in the aerospace industry. Figure shows the current block plan for the key manufacturing centers of the 75,000-square-foot facility.

Refer to the following closeness matrix and use rectilinear distance (the current distance from inspection to shipping and receiving is three units).
Alternative Layout 1

Alternative Layout 2

To calculate the change in the weighted distance, wd, score if Baker exchanges the locations of the tool crib andinspection.
