One effective means to hedge against uncertainty and better match supply with demand in a
swiftly changing environment is to adopt a flexible operations strategy that allows timely …

Motivated by centralized matching markets, we study an online stochastic matching problem
on edge-weighted graphs, where the agents' arrivals and abandonments are stochastic and …

Service systems abound with queues, but the most natural direct models are often time-
varying queues, which may require nonstandard analysis methods beyond stochastic …

Motivated by queues with multitype servers and multitype customers, we consider an infinite
sequence of items of types 𝒞={c 1,…, c I}, and another infinite sequence of items of types …

We consider an infinite sequence of customers of types and an infinite sequence of servers
of types where a server of type j can serve a subset of customer types C (j) and where a …

There are over 90,000 patients in the United States waiting for a kidney transplant. Under
the current allocation policy, the vast majority of deceased organs are allocated locally. This …

The model of FCFS infinite bipartite matching was introduced in Caldentey, Kaplan and
Weiss, 2009. In this model, there is a sequence of items that are chosen iid from a finite set 𝒞 …

We study a multiserver model with n flexible servers and n queues, connected through a
bipartite graph, where the level of flexibility is captured by an upper bound on the graph's …

We consider a multiclass multiserver queueing system and study the problem of designing
an optimal matching topology (or service compatibility structure) between customer classes …
