dispatcher

n. one who dispatches; one who oversees the departure of trains or other transport vehicles

For the short-term scheduler in computer multitasking, also called dispatcher, see scheduling (computing). Dispatchers are communications personnel responsible for receiving and transmitting pure and reliable messages, tracking vehicles and equipment, and recording other important information. A number of organizations, including police and fire departments, emergency medical services, taxicab providers,  trucking companies, train stations, and public utility companies, use dispatchers to relay information and coordinate their operations. Essentially, the dispatcher is the "conductor" of the force, and is responsible for the direction of all units within it.
