Page 383 2. Factor Rating Factor Rating General approach to evaluating locations that includes quantitative and qualitative inputs Procedure: 1. Determine which factors are relevant 2. Assign a weight to each factor that indicates its relative importance compared with all other factors. • Weights typically sum to 1.00 1. Decide on a common scale for all factors, and set a minimum acceptable score if necessary 2. Score each location alternative 3. Multiply the factor weight by the score for each factor, and sum the results for each location alternative 4. Choose the alternative that has the highest composite score, unless it fails to meet the minimum acceptable score

Page 384 3. Center of Gravity Method Center of Gravity Method Method for locating a distribution center that minimizes distribution costs Treats distribution costs as a linear function of the distance and the quantity shipped The quantity to be shipped to each destination is assumed to be fixed The method includes the use of a map that shows the locations of destinations The map must be accurate and drawn to scale A coordinate system is overlaid on the map to determine relative locations
