Stochastic Networks Conference 2026
Learn the latest in stochastic networks at this prestigious event sponsored by Chicago Booth.
Held biennially, this five-day event carries on the tradition of Stochastic Networks conferences initiated in 1987. The conference brings together mathematicians and applied researchers that share an interest in stochastic network models. Explore past conferences here. Student travel grant information is given at the bottom of the page. All participants are welcome to present a poster and should indicate their desire to do so when registering.
Dates: June 15–19, 2026
Location: Gleacher Center
Lodging: Book early! We have secured a limited number of discounted rooms at The Intercontinental Chicago Magnificent Mile and the Sheraton Grand Chicago Riverwalk. Once those rooms have been sold, we encourage out-of-town attendees to choose from the many other hotels available in the downtown Chicago area. Use the following links to book in one of our discounted blocks.

Title: Machine Learning, Casual Queueing, and SimLQ for Data Driven Simulation
Abstract: The objective of this talk is to expose researchers to the vast possibilities of using modern machinery and data for implementing effective management analytics for queueing processes. Such process are ubiquitous in modern economies, e.g., customers waiting to service, inventory waiting for processing/transportation, payments and invoices waiting to be generated/cleared, computing tasks waiting for resources.
I will discuss recent developments in queueing analysis based on several papers and our startup. We will first define management analytics along descriptive, predictive, comparative, i.e., comparing performance indicators under different interventions, and prescriptive analytics dimensions. We then shortly discuss ML solution for a G/G/1 based upon [1] and its extension to G(t)/G/1 based on [2].
Our main focus would be on structural causal queueing models (SCQM), based upon [3]. In this paper we suggest a data-driven representation of system building blocks to create a non-queueing simulator without prior knowledge of the system. We show that this approach is effective in comparative analytics, which, for simplicity, we demonstrate on analyzing expected waits for an M/M/1 with speed-ups.
The SCQM first requires to successfully refine the parent sets of queueing variables from data using, which we do using an off-the-shelf algorithm (even under a moderate sample size). We then use machine learning to estimate the causal structure in this queue, e.g., the Lindley's Recursion and use the G-computation to derive inference results of counterfactual interventions. We compare the performance of estimates obtained by a traditional closed form Queueing Theoretical (QT) analysis (that uses data driven estimates for the primitives of the queue) with SCQM based estimators. We find that the errors of the SCQM that assumes no knowledge of the system's dynamic and its features and these of the QT (which requires this knowledge) are comparable.
Our results suggest that SCQM would be effective for practical setting- where even experts QT analysis cannot provide closed-form results. We will finish with a demo of SiMLQ, see WWW.SiMLQ.COM. SiMLQ software uses Machine Learning to automate the visualization, Simulation, and optimization of Queueing processes. SiMLQ automatically constructs data-driven simulation models from event-log data collected by common information systems and enables users to improve processes resource management, increase efficiency, reduce cost, and manage risks. SiMLQ- from data to action!

Title: A Sanov-type Theorem for Marked Sparse Random Graph and its Applications
Abstract:
We prove a Sanov-type large deviation principle for the component empirical measure of certain families of sparse random graphs whose vertices are marked with i.i.d. random variables. Specifically, we show that the rate function can be expressed in a fairly tractable form involving suitable relative entropies.
We illustrate two applications of this result:
- We quantify probabilities of rare events in stochastic networks on sparse random graphs.
- We characterize the annealed free energy density of a broad class of probabilistic graphical models.
