Acme Machine is a job shop that makes specialty parts for the airline industry. Figure #1 below shows the block plan for key manufacturing operations in its current facility. Acme believes there may be a way to reduce the total distance traveled between departments. Consider the two revisions that have been suggested, based on the closeness matrix shown below the block plans. The aisles are shown by the dotted lines in Figure 1.
