The Joint Impact of COVID-19 Vaccination and Non-Pharmaceutical Interventions on Infections, Hospitalizations, and Mortality: An Agent-Based Simulation

Patel, M. D., Rosenstrom, E., Ivy, J. S., Mayorga, M. E., Keskinocak, P., Boyce, R. M., … Swann, J. L. (2021, January 4). (Vol. 1). Vol. 1.

TL;DR: Simulation results suggest that, as NPIs are removed, higher vaccination coverage with less efficacious vaccines can contribute to a larger reduction in risk of SAR-CoV-2 infection than compared to more efficacious vaccine at lower coverage. (via Semantic Scholar)

Staffing many-server queues with autoregressive inputs

NAVAL RESEARCH LOGISTICS, 68(3), 312–326.

By: X. Sun* & Y. Liu n

author keywords: autocorrelation; heavy‐ traffic approximations; many‐ server queues; mean‐ reverting process; non‐ Poisson arrivals; optimal staffing; parameter uncertainty; queues with customer abandonment
TL;DR: A multiserver queueing system where customer arrivals follow a doubly stochastic Poisson point process whose intensities are driven by a Cox–Ingersoll–Ross (CIR) process is studied, finding that, in order to achieve the designated service level, such an autoregressive feature in the arrival model translates into notable adjustment in the staffing formula, and such an adjustment can be fully characterized by the parameters of the new arrival model.
