Case questions.

The North Carolina Domes Professional Baseball Stadium Case

The governor and mayors of the largest cities in North Carolina agree that the state needs a
domed Major League Baseball stadium. They also agree that the citizens of North Carolina
and its tourists can only afford one. But where should it be put? Naturally, the political
leaders cannot agree on where to build it. Unbiased consultants from your company were
called in to study the problem. They suggested that the 10 most populated counties in
North Carolina be treated as “supply points” and that the optimal site be determined by
using an unbiased, mathematical facility location model. The consultants justified their
suggestions by noting that: (1) a mathematical model would be politically unbiased, (2) the
location based on a mathematical model would probably be economically and logistically
logical, and (3) regardless of where you put the domed stadium, not everyone will be
satisfied anyway.

A. Using the map of North Carolina provided develop a grid system showing clearly the
X and Y coordinates used to locate the 10 counties most populated counties. Since
the domed stadium cannot be completed before 2025 use the North Carolina county
population data for 2025 listed in the table provided. Note: A downloadable version
of the data can be found on the following webpage:
https://files.nc.gov/ncosbm/demog/countytotals_populationoverview.html

B. Using the Center of Gravity technique determine the optimal mathematical location

for the domed stadium.

C. While mathematical location models are “blind” to the realities of highways, lakes,
rivers, mountains, etc., does the location determined by the math model makes any
sense? Justify your answer. Could the mathematical location be used as a starting
point and slightly “moved” to a different location that makes greater geographical,
logistical, and economic sense? If so, to where would suggest the location be moved
and why?

D. Would the mathematical location be any different if you used the population
estimates for 2030?
