Samenvatting
Buses, trains, aircraft, ships and possibly, in time, automobiles depart by schedules and are subjects to en route control. As flow control is more intensively established it becomes appropriate to identify the effects of scheduling and to establish a basis for choosing dispatching quantum, frequency and time. Design of these values can achieve objectives jointly for traveler's using the system and managers operating it. An initial formulation to this end is presented with a discussion of some typical results.
