The Number of Overlapping Customers in Erlang-A Queues: An Asymptotic Approach
Young Myoung Ko, Jamol Pender, Jin Xu
In this paper, we investigate the number of customers that overlap or coincide with a virtual customer in an Erlang-A queue. Our study provides a novel approach that exploits fluid…
Overlapping time of a virtual customer in time-varying many-server queues
Young Myoung Ko, Jin Xu
Motivated by the ongoing COVID-19 pandemic, this paper investigates customers' infection risk by evaluating the overlapping time of a virtual customer with others in queueing syste…
Critically loaded multi-server queues with abandonments, retrials, and time-varying parameters
Young Myoung Ko, Natarajan Gautam
In this paper, we consider modeling time-dependent multi-server queues that include abandonments and retrials. For the performance analysis of those, fluid and diffusion models cal…
Effectively tailoring fluid and diffusion models for non-stationary state-dependent queueing systems
Young Myoung Ko, Natarajan Gautam
In this paper, we consider queueing systems where the dynamics are non-stationary and state-dependent. For performance analysis of these systems, fluid and diffusion models have be…
