Question Set 3. This question set uses the metropolitan model for facility location decisions. Each demand source has a weight indicating the volume of sales it is expected to generate. Using the demand data and five potential locations below: 1. Find the sum of weighted metropolitan model distances for each of the five locations: A1, A2, A3, A4 and A5. Be sure the calculations are shown for each location's sum of distances. (Spts) 2. As evidenced by having the smallest weighted sum of distances, which location is best?
