Shift minimization personnel task scheduling

There are currently 137 data files with number of workers and jobs in the range 22 <=|W|<= 420 and 40 <=|J|<= 2105; and with tightness 90%.

These data files are from M. Krishnamoorthy, A.T. Ernst and D. Baatar "Algorithms for Large Scale Shift Minimisation Personnel Task Scheduling Problems" European Journal of Operational Research Volume 219, Issue 1, 2012, Pages 34–48.

The format of all of these data files is:

The name of the data file presents:

For example, Data_10_51_111_66.dat is the 10th data file which presents a problem instance with 51 workers, 111 jobs and with a multi–skilling level of 66%.

These test problems were contributed by D. Baatar (davaatseren.baatar@eng.monash.edu.au)
