In the absence of valid medicines or vaccine, quarantine and isolation strategies are the most important and effective measures against the SARS outbreaks. This paper discusses the application of the optimal and sub-optimal control for SARS outbreak control via the Pontryagin’s Maximum Principle and genetic algorithm, respectively. To this end, a pair of control variables representing the quara...

Information spreading in a population can be modeled as an epidemic. Campaigners (e.g. election campaign managers, companies marketing products or movies) are interested in spreading a message by a given deadline, using limited resources. In this paper, we formulate the above situation as an optimal control problem and the solution (using Pontryagin’s Maximum Principle) prescribes an optimal re...

Animal epidemics can bring severe damage to the livestock sector as well as the whole society. In controlling animal epidemic, the selection of suboptimal control strategies may lead to unnecessary costs which should be avoided. This paper argues that uncertainties about the state of the epidemic, irreversible actions like culling and vaccination of animals, and the possibility of learning duri...

This research paper considers the dynamics in epidemic model. Since understanding mechanism of spread and transmission a disease, is very crucial preventing controlling disease. We describe mechanisms disease model infectious agents. Optimal control theory was used to deduce optimal strategy aimed at curtailing syphilis.

this paper deals with optimal operation of a three-product dividing-wall column (dwc). the main idea is to design a control structure, through a systematic procedure for plantwide control, with an objective to achieve desired product purities with the minimum use of energy. exact local method is used to find the best controlled variables as single measurement or combination of measurements base...

Despite extensive work on the interplay between traffic dynamics and epidemic spreading, the control of epidemic spreading by routing strategies has not received adequate attention. In this paper, we study the impact of efficient routing protocol on epidemic spreading. In the case of infinite node-delivery capacity, where the traffic is free of congestion, we find that that there exists optimal...
