Optimal control of information epidemics modeled as Maki Thompson rumors
We model the spread of information in a homogeneously mixed population using the Maki Thompson rumor model. We formulate an optimal control problem, from the perspective of single campaigner, to maximize the spread of information when the campaign budget is fixed. Control signals, such as advertising in the mass media, attempt to convert ignorants and stiflers into spreaders. We show the existe...
متن کاملOptimal control of epidemics in metapopulations.
Little is known about how best to deploy scarce resources for disease control when epidemics occur in different but interconnected regions. We use a combination of optimal control methods and epidemiological theory for metapopulations to address this problem. We consider what strategy should be used if the objective is to minimize the discounted number of infected individuals during the course ...
متن کاملDynamics of Dengue epidemics using optimal control
We present an application of optimal control theory to Dengue epidemics. This epidemiologic disease is an important theme in tropical countries due to the growing number of infected individuals. The dynamic model is described by a set of nonlinear ordinary differential equations, that depend on the dynamic of the Dengue mosquito, the number of infected individuals, and the people’s motivation t...
متن کاملOptimal Control of Mobile Malware Epidemics
Malware attacks constitute a serious security risk that threatens our ever-expanding wireless networks. Developing reliable security measures against outbreaks of malware facilitate the proliferation of wireless technologies. The first step towardthis goal is to investigate potential attack strategies and the extent of damage they can incur. Given the flexibility that software-based operation p...
متن کاملOptimal control of epidemics with limited resources.
We extend the existing work on the time-optimal control of the basic SIR epidemic model with mass action contact rate. Previous results have focused on minimizing an objective function that is a linear combination of the cost associated with using control and either the outbreak size or the infectious burden. We instead, provide analytic solutions for the control that minimizes the outbreak siz...
