For the 88-node data set (CITY1990.GRT) and the first demand set in the file, use SITATION to find all points on the tradeoff curve of uncovered demand versus average distance (as was done in Section 8.2). Use a coverage distance of 300 and 7 facilities. Plot the results carefully using a spreadsheet. Also include a table of the following form:

You can either do this by hand (identifying the appropriate weights yourself) or you can use the automated Trade off Curves from the MAIN MENU of SITATION to find the trade off curve. If you solve this yourself, you can enter the weight to be used for uncovered demand on the Lagrangian Options Menu for the P-median model. We suggest you solve this on your own and then check your solution using the automated procedure.
