We provide a unified framework for the total tardiness problem by surveying the related literature in the single-machine, parallel machine, flowshop and jobshop settings. We focus on critically evaluating the heuristic algorithms; we also propose new heuristics for both the single-machine and the parallel-machine tardiness problems. Finally, we identify the areas where further research is needed and we give directions for future research.
