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 13 data files. These data files are the test problems used in the papers "Scheduling aircraft landings - the static case" by J.E. Beasley, M. Krishnamoorthy, Y.M. Sharaiha and D. Abramson, Transportation Science, vol.34, 2000, pp180-197; and "Displacement problem and dynamically scheduling aircraft landings" by J.E. Beasley, M. Krishnamoorthy, Y.M. Sharaiha and D. Abramson, Journal of the Operational Research Society, vol.55, 2004, pp54-64. The test problems are the files: airland1, airland2, ..., airland13 The first eight files are those used in the Transportation Science paper referred to above. The format of these data files is: number of planes (p), freeze time for each plane i (i=1,...,p): appearance time, earliest landing time, target landing time, latest landing time, penalty cost per unit of time for landing before target, penalty cost per unit of time for landing after target for each plane j (j=1,...p): separation time required after i lands before j can land The value of the optimal solution for each of these data files for a varying number of runways is given in the above papers. The largest file is airland13 of size 800Kb (approximately). The entire set of files is of size 1.3Mb (approximately).
