A Two-Stage Operating Room Allocation Framework for Reducing Surgical Waiting Lists in Public Hospitals
Jhoan Báez, Juan Hoyos, Víctor Riquelme +2
Operating-room allocation is a major challenge for public hospitals with limited surgical capacity and large elective waiting lists. This work proposes a two-stage operating-room a…
Inmate population models with nonhomogeneous sentence lengths and their effects in an epidemiological model
Pedro Gajardo, Victor Riquelme
In this work, we develop an inmate population model with a sentencing length structure. The sentence length structure of new inmates represents the problem data and can usually be…
Optimal control of diseases in prison populations through screening policies of new inmates
Pedro Gajardo, Victor Riquelme, Diego Vicencio
In this paper, we study an optimal control problem of a communicable disease in a prison population. In order to control the spread of the disease inside a prison, we consider an a…
A Hamilton-Jacobi approach of sensitivity of ODE flows and switching points in optimal control problems
Victor Riquelme
In optimal control problems of control-affine systems, whose solutions are bang-bang or singular type, verification of optimality using the Hamilton-Jacobi-Bellman (HJB) equation i…
Optimal feedback synthesis and minimal time function for the bioremediation of water resources with two patches
Hector Ramirez, Alain Rapaport, Victor Riquelme
This paper studies the bioremediation, in minimal time, of a water resource or reservoir using a single continuous bioreactor. The bioreactor is connected to two pumps, at differen…
