Time Slot Management (TSM) is an online reservation system that allows to schedule transports from the dispatcher’s position for a specific day or time window. When creating time slots, it is possible to set various constraints from the administrator’s position, such as the length of the time slot and their maximum number, considering working hours, etc., in order to achieve the highest possible efficiency of ramp and handler utilization. Of course, there is a link with third-party IS such as SAP, Vision, ABRA, etc., from which can be drawn information for transport planning.
