OR-Library is a collection of test data sets for a variety of OR problems.
A full list of the test data sets available in OR-Library can be found here.
There are currently 10 data files. These data files are the first 10 test problems from J.E.Beasley "Fixed routes" Journal of the Operational Research Society 35 (1984) 49-55. Test problems 1, 2, ..., 10 from that paper are available in files fixed1, fixed2, ..., fixed10 respectively. The format of these data files is: number of customers (n), number of days for each customer i (i=1,...,n): demand of that customer on each day in turn See the file vrpinfo for details of how to access the data needed to calculate inter-customer distances. The entire set of files is of size 15Kb (approximately).
