79. A suggestion has been made to switch Hardware and Automotive. What would the total weighted-distance (wd) score for the entire store if these two departments were switched?

a. less than or equal to 1,000

b. greater than 1,000 but less than or equal to 1,500

c. greater than 1,500 but less than or equal to 2,000

d. greater than 2,000

80. Based on your calculations, would you recommend that Hardware and Toys be switched?

a. Yes, and this is an improvement of 200 – 300 in the weighted-distance (wd) score.

b. No, the travel distances are the same.

c. Yes, and this is a difference of over 300 feet in the weighted-distance (wd) score.

d. We don’t have enough information to determine this.

Figure 3.1

The information systems and operations management department of a small college is now designing its layout for newly built office space. An overhead view of the available office space reveals the following (note: assume all locations are measured from center point to center point):

	C
	D
	E
	F
A	B

Each block in the graph is 10 feet by 10 feet. Therefore, point

locations are:
A: 10, 10	D: 20, 40
B: 50, 10	E: 60, 30
C: 40, 50	F: 30, 20
