Title: Analysis and Control of Stochastic Networks: From Data Centers to Transportation Systems
Modern large-scale stochastic systems face much demand and processing variability, and a key challenge is the design of efficient control and scheduling policies that are robust to these uncertainties. In this talk, I will present several robust scheduling policies for stochastic models with applications to emerging sectors such as data centers and intelligent transportation systems. In the first part, I present a robust scheduling policy with performance guarantee, for a novel stochastic model of job scheduling in data centers, where jobs are represented as directed acyclic graphs (DAG). I will then visit the long-standing open problem on the stability of of the longest-queue-first scheduling policy for multiclass open queueing networks, and resolve this problem for an important special case. In the second part of the talk, I focus on transportation networks. I develop the first exact analysis of fixed-time control for urban networks, and briefly mention a few opportunities and challenges in exploiting feedback control policies.
