A Two-Time-Scale Approach to Time-Varying Queues in Hospital Inpatient Flow Management

Dai, J.; Shi, Pengyi - 2017

We analyze a time-varying Mperi/Geo2timeScale/N queueing system. The arrival process is periodic Poisson. The service time of a customer has components in different time scales: length of stay (LOS) in days and departure time (hdis) in hours. This queueing system has been used to study patient...
