Path integral control of a stochastic multi-risk SIR pandemic model

Theory Biosci. 2023 Mar 11:1-36. doi: 10.1007/s12064-023-00388-y. Online ahead of print.ABSTRACTIn this paper a Feynman-type path integral control approach is used for a recursive formulation of a health objective function subject to a fatigue dynamics, a forward-looking stochastic multi-risk susceptible-infective-recovered (SIR) model with risk-group's Bayesian opinion dynamics toward vaccination against COVID-19. My main interest lies in solving a minimization of a policy-maker's social cost which depends on some deterministic weight. I obtain an optimal lock-down intensity from a Wick-rotated Schrödinger-type equation which is analogous to a Hamiltonian-Jacobi-Bellman (HJB) equation. My formulation is based on path integral control and dynamic programming tools facilitates the analysis and permits the application of algorithm to obtain numerical solution for pandemic control model.PMID:36899154 | PMC:PMC10005926 | DOI:10.1007/s12064-023-00388-y
