One of the main tasks of the Qguar YMS system is to ensure smooth servicing of vehicle visits. This involves elimination of bottlenecks and optimum usage of the capacities of logistics facilities used in servicing of vehicle visits (i.e., access gates, external and internal parking lots, docking bays, etc.). Up-to-date information about current and planned visits and potential deviations from plans enables quick reaction to problem and increases yard performance.
