1. Convert the load distance values to be used as scores in the factor rating method. (20 marks)

LD= [L;* Di] Where, LD = load-distance value L = load (weight) shipped from proposed facility to location i Di = distance between the proposed facility and location i (straight line distance) The distance (D) in this formula can be the distance travelled (if the values are known) or it can be determined from a map. It can also be computed by using the formula for the straight line or minimum distance between two points, which is also the hypotenuse of a right angle triangle: D; = SQRT [(x; x)2 + (y;- y)1 Where, x, y = co-ordinates of proposed facility location Xi, yi = co-ordinates of existing facility i LD= [L;* Di] Where, LD = load-distance value L = load (weight) shipped from proposed facility to location i Di = distance between the proposed facility and location i (straight line distance) The distance (D) in this formula can be the distance travelled (if the values are known) or it can be determined from a map.
