Self-reporting and screening: Data with current-status and censored observations
Jonathan Yefenof, Yair Goldberg, Jennifer Wiler +2
We consider survival data that combine three types of observations: uncensored, right-censored, and left-censored. Such data arises from screening a medical condition, in situation…
Workload forecasting for a call center: Methodology and a case study
Sivan Aldor-Noiman, Paul D. Feigin, Avishai Mandelbaum
Today's call center managers face multiple operational decision-making tasks. One of the most common is determining the weekly staffing levels to ensure customer satisfaction and m…
The Best Linear Unbiased Estimator for Continuation of a Function
Yair Goldberg, Ya'acov Ritov, Avishai Mandelbaum
We show how to construct the best linear unbiased predictor (BLUP) for the continuation of a curve in a spline-function model. We assume that the entire curve is drawn from some sm…
Queueing systems with many servers: Null controllability in heavy traffic
Rami Atar, Avi Mandelbaum, Gennady Shaikhet
A queueing model has heterogeneous service stations, each consisting of many independent servers with identical capabilities. Customers of classes can be served at…
Scheduling a multi class queue with many exponential servers: asymptotic optimality in heavy traffic
Rami Atar, Avi Mandelbaum, Martin I. Reiman
We consider the problem of scheduling a queueing system in which many statistically identical servers cater to several classes of impatient customers. Service times and impatience…
Coalescence of skew Brownian motions
Martin Barlow, Krzysztof Burdzy, Haya Kaspi +1
We prove that two skew Brownian motions with the same skewness parameter (different from 0) and driven by the same Brownian motion coalesce a.s.
