The Association of American Railroads wished to determine the effect of a maintenance practice known as grinding on the occurrence of rail fatigue defects and on the subsequent total traffic usage before a track must be replaced. Because a designed experiment was not practical, an analysis of historical data from the Canadian Northern Railroad is presented. In the analysis, certain covariate da...

In this paper, we introduce tracks. A track is a global constraint for parallelizing the execution of task sets in non-preemptive scheduling. We give algorithms for bound as well as for domain reasoning, we propose applications in school timetabling, and we report results of a large-scale empirical study. Section 2 introduces concepts and notations we rely on. Section 3 defines tracks in terms ...
