About

Arie Hordijk is a distinguished researcher in the field of stochastic operations research, with a primary focus on optimal control and routing in queueing systems. His work addresses fundamental challenges in network resource allocation, particularly in environments with limited or no buffer capacity. Hordijk’s major contributions lie in developing analytical frameworks for admission, routing, and service assignment control, where decisions must be made under uncertainty and without real-time state information. His most-cited paper, "Optimal admission, routing and service assignment control: the case of single buffer queues" (2002, 20 citations), tackles the problem of maximizing throughput in systems with parallel servers and no waiting room, providing optimal policies for packet routing to minimize loss rates. In his earlier work, "Open-loop routeing to M parallel servers with no buffers" (2000, 6 citations), he explores routing strategies when the controller lacks server state knowledge, relying instead on historical timing information. These contributions are particularly valuable for designing efficient communication networks and manufacturing systems where real-time feedback is unavailable. Hordijk’s research continues to influence the development of robust, state-independent control policies in stochastic environments.
