The weighted-workload-task-allocation (WWTA) load-balancing policy is known to be throughput optimal for parallel server systems with heterogeneous servers. This work concerns the heavy traffic approximation of steady-state performance for parallel s

This paper studies the continuous-time join-the-shortest-queue (JSQ) system with general interarrival and service distributions. Under a much weaker assumption than the one in the literature, we prove that each station's scaled steady-state queue len

In Braverman et al. (2024), the authors prove that the stationary distribution of a multiclass queueing network converges to the stationary distribution of a semimartingale reflecting Brownian motion (SRBM) in heavy traffic. Among the sufficient cond

In this work, we study the stationary distribution of the scaled queue length vector process in multi-class queueing networks operating under static buffer priority service policies. We establish that when subjected to a multi-scale heavy traffic con

We establish uniform moment bounds for steady-state queue lengths of generalized Jackson networks (GJNs) in multi-scale heavy traffic as recently proposed by Dai et al. [2023]. Uniform moment bounds lay the foundation for further analysis of the limi

We prove that under a multi-scale heavy traffic condition, the stationary distribution of the scaled queue length vector process in any generalized Jackson network has a product-form limit. Each component in the product form has an exponential distri

The basic adjoint relationship (BAR) approach is an analysis technique based on the stationary equation of a Markov process. This approach was introduced to study heavy-traffic, steady-state convergence of generalized Jackson networks in which each s

The policy improvement bound on the difference of the discounted returns plays a crucial role in the theoretical justification of the trust-region policy optimization (TRPO) algorithm. The existing bound leads to a degenerate bound when the discount

We collaborate with a large teaching hospital in Shenzhen, China and build a high-fidelity simulation model for its ultrasound center to predict key performance metrics, including the distributions of queue length, waiting time and sojourn time, with
