on neighborhood affluence, traffic patterns, etc. The distributor will
be concerned with speedy and reliable delivery, the supermarket

Both will need access to similar labor forces; both will need similar
measures of workforce education, etc. Many other comparisons can
be drawn.

1. What is the total weighted distance from the current old and
inadequate warehouse in Pittsburgh?
318,692
2. If they relocate their warehouse to the center of gravity, by
how much will this reduce the total weighted shipping distance?
By 18,663—from 318,692 to 300,029.
3. Observe the graph. If the number of shipments from New
York doubles, how does this affect the center of gravity?
The center of gravity moves north and east.
4. The center of gravity does not necessarily find the site with
the minimum total weighted distance. Use the scrollbars to move
the trial location and see if you can improve (lower) the distance.
