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.

USE THE FOLLOWING TO
ANSWER QUESTIONS 76 – 80.

A department store chain is designing a layout for a
new store. The store manager wants to provide as much convenience as possible
for her customers. Based on historical data, the number of trips between
departments per hour is given in the following closeness matrix. A block plan
showing a preliminary layout is also shown.
