12. The center-of-gravity method assumes that cost is directly
proportional to both distance and volume shipped. For service
facilities, revenue is assumed to be directly proportional to prox-
imity to markets.
LO 8.5: Use the center-of-gravity method
13. Locational break-even analysis has three steps:
◼ Step 1: Determine fixed and variable cost for each location.
LO 8.2: Compute labor productivity
16. Service location techniques: regression models to determine
importance of various factors, factor rating method, traffic counts,
demographic analysis of drawing area, purchasing power analysis of
area, center–of–gravity method, and geographic information system.
LO 8.6: Understand the differences between service- and indus-
trial-sector location analysis
17. The distributor is more concerned with transportation and
ETHICAL DILEMMA
Location is a major issue in the U.S. today. Almost every
community is seeking new jobs, especially from foreign firms like
Mercedes. As Mercedes was definitely coming to the U.S. any–
way, the bidding wars are nonproductive from a central economy
perspective. There are many implications to the local citizenry,
especially because they pay the bills if the financial successes
predicted are not accurate. Votes are usually not taken as these
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.
64, 97 (with a total weighted distance of 299,237).
5. If you have Solver set up in Excel, from Excel’s main menu,
