Model by hand and OPL

4. Given the following distance matrix. Assume that row 1 represents the home base of a vehicle routing problem. Each customer needs to be visited exactly one time and you want to minimize the total distance traveled Model this problem as an IP, solve it in OPL and report the solution (use a script file) A. Do this if you have 6 vehicles and each vehicle must visit exactly two customers B. Try to do this for 3 vehicles where each vehicle must visit at least two customers [[0,2457,712,1433,66,2141,1616,635,2407,1104,644,1167,1057], 2457,0,1752,1374,2409,365,851,1853,958,2339,1817,1688,1775], [712,1752,0,954,672,1452,906,275,1737,1195,167,838,778], 1433,1374,954,0.1368,1010,871,829,1891,967,878,336,445], 66,2409,672,1368,0,2090,1572,577,2383,1047,593,1101,991], 2141,365,1452,1010,2090,0,593,1522,1,1974,1498,1324,1412], 1616,851,906,871,1572,593,0,1039,1033,1710,987,1078,1124], 635,1853,275,829,577,1522,1039,0,1956,920,108,633,550], 2407,958,1737,1891,2383,1111,1033,1956,0,2732,1874,2110,2151], 1104,2339,1195,967,1047,1974,1710,920,2732,0,1028,654,587], [644,1817,167,878,593,1498,987,108,1874,1028,0,713,640], 1167,1688,838,336,101,1324,1078,633,2110,654,713,0,117, 1057,1775,778,445,991,1412,1124,550 2151 587 640,117,0] 4.
