Table 9.4 Table 7.4 A company has determined the "demand points" and their relative locations as follows: Coordinates Demand Point Demand 10 10 100 10 20 200 15 10 150 20 10 200 -Using the information in Table 9.4.If a company desires to locate a manufacturing facility at the center of gravity,what would be the x- and y-coordinates of the facility?

A company desires to locate a new facility.Based on preliminary analysis,the choice has been reduced to four locations: A,B,C,and D.These four locations were rated on a scale from 1 (worst)to 10 (best)on each of four criteria.Each criterion was also weighted to indicate its importance (i.e.,the higher the weight,the more important).The list of ratings and weights follows. Location Factor Weight A B C D Wages 0.40 7 5 3 5 Labor Climate 0.35 6 5 9 5 Local Regulation 0.15 3 4 3 2 Weather 0.10 2 8 6 9 Based on weighted scores,where should the company locate its new facilities?
