Aronsson, Martin and Bohlin, Markus and Kreuger, Per (2007) Mixed integer-linear formulations of cumulative scheduling constraints - A comparative study. [SICS Report]
This paper introduces two MILP models for the cumulative scheduling constraint and associated pre-processing filters. We compare standard solver performance for these models on three sets of problems and for two of them, where tasks have unitary resource consumption, we also compare them with two models based on a geometric placement constraint. In the experiments, the solver performance of one of the cumulative models, is clearly the best and is also shown to scale very well for a large scale industrial transportation scheduling problem.
