Planning rolling stock maintenance: Optimization of train arrival dates at a maintenance center

<p style='text-indent:20px;'>A railway network is an indispensable part of the public transportation system in many major cities around world. In order to provide a safe and reliable service, fleet passenger trains must undergo regular maintenance. These maintenance operations are lengthy procedures, which planned for one year or longer period. The planning specifies dates trains' arrival at center should take into account uncertain duration operations, periods validity previous maintenance, desired number capacity center. paper presents nonlinear programming formulation considered problem several optimization procedures were compared by computational experiments using real world data. results these indicate that presented approach capable be used process.</p>
