Problem 4-4

Durham Toy, Inc. has five distribution centers at the location coordinates given as follows. The monthly demand at each center is also given.

DC	Coordinates	Demand
A	(10, 12)	40
B	(25, 30)	25
C	(8, 15)	30
D	(11, 20)	10
E	(25, 6)	20

A) x > 14, y > 15

B) x < 14, y > 15

C) x < 14, y < 15

D) x > 14, y < 15

2) Use the information in Table 13.3. If the plant is located at the center of gravity, what is the load-distance score, assuming rectilinear distance?

A) less than or equal to 1500

B) more than 1500 but less than or equal to 1600

C) more than 1600 but less than or equal to 1700

D) more than 1700
