Local Reproduction Numbers for Analysis and Optimal Mitigation of Epidemic Processes
José I. Caiza, Junjie Qin, Philip E. Paré
In this paper, we propose a unifying framework to analyze layered networked epidemic processes where the population, represented either as a networked SIS or SIR model, is coupled…
A Networked SIS Epidemic--Opinion Model with Higher-Order Interactions
Saba Samadi, José I. Caiza, Sebin Gracy +1
This paper studies a susceptible--infected--susceptible (SIS) epidemic model coupled with opinion dynamics over a network of communities with higher-order interactions. Unlike stan…
Global and Distributed Reproduction Numbers of a Multilayer SIR Model with an Infrastructure Network
José I. Caiza, Junjie Qin, Philip E. Paré
In this paper, we propose an SIR spread model in a population network coupled with an infrastructure network that has a pathogen spreading in it. We develop a threshold condition t…
Optimal Ordering Policies for Multi-Echelon Supply Networks
Jose I. Caiza, Ian Walter, Jitesh H. Panchal +2
In this paper, we formulate an optimal ordering policy as a stochastic control problem where each firm decides the amount of input goods to order from their upstream suppliers base…
