1) Center of Gravity Model
Table 1 Calculation Center of Gravity Model
Figure 1 the center of gravity model
According to the requirement from City Council Members, the weighted of important places (included the Population Center) had ranked in the table above. The highest weight mean the important of that location. Therefore, according to the center gravity model, the best result of the training stadium site is the red dot in the figure 1.
2) Weighted Scoring Model
Table 2 Calculation of Weight Scoring Model (Considering the Cost)
According to table, the best stadium site from all the candidate would be Site C, because the weighted score of Site C is the highest among all Sites. However, the weight ranked by the important of the issues in the future.
On the other hand, the Site C does not include the Cost of the Land, because it is a wetland and preserve area, so that it is not fair to other sites, which they have the land cost. Therefore, I come up with the new Table that not consider the cost of the land.
Table 3 Calculation of Weight Scoring Model (without Considering the Land Cost)
Therefore, it turn out to be that the Site D has the best score among all the sites.
PS: The minus sign means the value is negative because it is a cost.
3) Combine the result from Center of Gravity Model and Weight Scoring Model
Accord to the answers from Figure1 and Table3, the best result would be the Stadium Site A because it in between the “Best Point” and the weight scoring is nearly the same as site-D
4) Final Recommendation
According to these analysis and modeling, the best site would be the Site A for two reasons. First, Site A is closed to two major Shopping Malls, which this could provide the jobs in the area and generate more revenue in the area. Second, it is very close to the Interstate 75 (I-75) which means it is very easy to access the stadium from the Airport and the stadium would be the new landmark for the city,
