Inpatient Overflow Management with Proximal Policy Optimization
Jingjing Sun, Jim Dai, Pengyi Shi
Problem Definition: Managing inpatient flow in large hospital systems is challenging due to the complexity of assigning randomly arriving patients -- either waiting for primary uni…
A High-fidelity, Machine-learning Enhanced Queueing Network Simulation Model for Hospital Ultrasound Operations
Yihan Pan, Zhenghang Xu, Jin Guang +10
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…
High order steady-state diffusion approximation of the Erlang-C system
Anton Braverman, J. G. Dai
In this paper we introduce a new diffusion approximation for the steady-state customer count of the Erlang-C system. Unlike previous diffusion approximations, which use the steady-…
Asymptotic optimality of maximum pressure policies in stochastic processing networks
J. G. Dai, Wuqin Lin
We consider a class of stochastic processing networks. Assume that the networks satisfy a complete resource pooling condition. We prove that each maximum pressure policy asymptotic…
