Use SITATION to find the trade off between the average and maximum distance for P = 5 facilities using the 2010 Counties Sorted 250.grt data set.

(a) Plot the trade off curve.

(b) How many solutions does SITATION find?

(c) What is the largest maximum distance of any solution? What is the smallest maximum distance of any solution?

 (d) What are the smallest and largest demand-weighted average distances for all solutions?

(e) Is SITATION using the weighting method or the constraint method in finding these solutions?

(f) As you progress along the trade off curve from the solution with the smallest maximum distance to the one with the largest maximum distance, are there any facility sites that remain in place for all solutions on the trade off curve? If so, where are these sites? Are there any sites whose assigned demand remains the same for all solutions on the trade off curve?
