We study a situation where jobs of unknown duration (e.g., surgical procedures) are performed sequentially in a single facility (e.g., a hospital operating room). This facility can be any resource (material or human) that is in limited supply. Due to the uncertain duration of jobs, the time at...

We consider a simple, deterministic queueing system with feedback, which exhibits the phenomena of sustained oscillation, mode locking, quasi-periodic behaviour, and chaos. This implies that a fully deterministic queueing system can exhibit seemingly unpredictable behaviour. We ignore...
