Wheel/rail rolling noise is generally the predominant noise component radiated by railway systems. Considerable R and D work on rolling noise control has been initiated by the major railway companies during the last few decades which has led to the development of a signi"cant number of technical sol

To avoid difficulties associated with the computation of optimal singular/bang-bang controls, a common approach is to add a perturbed energy term. The efficacy of this perturbation method is assessed here via a direct search iterative dynamic programming procedure. A potential limitation of the stra
## a b s t r a c t In this survey we review the current complexity status of basic cyclic scheduling models. We start with the formulations of three fundamental cyclic scheduling problems, namely the cyclic jobshop, cyclic flowshop, and cyclic project scheduling problems. We present state-of-the-ar
