Optimizing Hospital Infection Control: The Role of Mathematical Modeling
Infection Control & Hospital Epidemiology, 2014Multidrug-resistant bacteria are major causes of nosocomial infections and are associated with considerable morbidity, mortality, and healthcare costs. Preventive strategies have therefore become increasingly important. Mathematical modeling has been widely used to understand the transmission dynamics of nosocomial infections and the quantitative ...

Optimal control in a mathematical model for tumor escape
2018 IEEE International Conference on Bioinformatics and Biomedicine (BIBM), 2018This paper deals with the medical treatment of tumors which are able to escape the immune system surveillance. A mathematical model for the tumor immune system competition is generalized by introducing a therapy which helps the immune system cells to recognize the tumor cells.

A mathematical formulation for optimal control of air pollution
Science in China Series D: Earth Sciences, 2003The problem of optimal control of air pollution using weather forecast results and nu-merical air pollution models is discussed. A mathematical formulation of the problem is presented. The control is an act on pollution sources with feasible constraints.

Optimal control analysis of a mathematical model on smoking
Modeling Earth Systems and Environment, 2020In this paper,the dynamics of smoking behavior under the influence of educational and media programs is modeled in the presence of two control strategies. Optimal control theory is applied to a non-linear mathematical model on smoking: impact of anti-smoking campaign which helps in obtaining time dependent case detection strategy while minimizing the ...

Mathematical modelling and optimal control of solar dryers
Mathematical Modelling of Systems, 1997A mathematical model of the solar dryers designed and used in Cuba is presented and discussed. The model consists of a set of ordinary nonlinear differential equations which describe the behaviour of the main parts of the dryer. Using the model, an optimal control problem is formulated and solutions within the class of piecewise constant controls are ...

Optimal control analysis of a mathematical model for unemployment
Optimal Control Applications and Methods, 2015SUMMARYUnemployment is continuously increasing worldwide because of enormous increase in population. This paper attempts to propose an optimal control policy for a deterministic unemployment model. The model considers three states, namely, unemployment, employment, and newly created vacancies.

Mathematical modeling and optimal control of corruption dynamics
Asian-European Journal of Mathematics, 2018The problem of corruption is of serious concern in all the nations, more so in the developing countries. This paper presents the formulation of a corruption control model and its analysis using the theory of differential equations. We found the equilibria of the model and stability of these equilibria are discussed in detail.

Adaptive Controllers for Mathematical Optimization Models
2011Adaptive model controllers are promising candidates for extending DSS for dynamic process planning problems. They are designed to feed back variations of model assumptions about the severity of a process control problem to the model base during the process control phase.

Optimal Control of Mathematical Models for Antiangiogenic Treatments
2015In the models considered so far, the focus was on the cancerous cells progressing from mathematical models for homogeneous tumor populations of chemotherapeutically sensitive cells to heterogeneous structures of cell populations with varying sensitivities or even resistance. From an optimal control point of view, optimal treatment schedules change from
