A single facility is to be located to meet the demand at coordinates (1, 2), (2, 3), (3, 5) and (4, 1). The demand at these points is 700, 100, 300 and 500 respectively. Using the rectilinear distance measure and weighted distance minimization criterion, the facility should be located
1
anywhere on the line joining points (2, 2) and (3, 2)
2
at the point (2, 3)
3
anywhere on the line joining (2, 3) and (3, 3)
4
at the point (3, 3)
