Optimal Resource Allocation to Reduce an Epidemic Spread and Its Complication

Information

Mathematical modeling represents a useful instrument to describe epidemic spread and to propose useful control actions, such as vaccination scheduling, quarantine, informative campaign, and therapy, especially in the realistic hypothesis of resources limitations. Moreover, the same representation could efficiently describe different epidemic scenarios, involving, for example, computer viruses spreading in the network. In this paper, a new model describing an infectious disease and a possible complication is proposed; after deep-model analysis discussing the role of the reproduction number, an optimal control problem is formulated and solved to reduce the number of dead patients, minimizing the control effort. The results show the reasonability of the proposed model and the effectiveness of the control action, aiming at an efficient resource allocation; the model also describes the different reactions of a population with respect to an epidemic disease depending on the economic and s...

Epidemic Control: Simulation of Delaying Epidemic through flight cancellation

Study of Spreading of disease through travel network has recently become one of the important research topic. Airplane network is most crucial among them as they can quickly propagate the disease around the world. In this simulation we have tested various strategies to slow down the propagation of epidemic. We have used open flight airplane network dataset to test the different strategies to slow down the propagation around the network. One of the main and effective strategy to do this is to shut down the big airport, these airports are giant HUB in the network but at the same place this strategy is very expensive for mankind. The other strategy would be edge removal, cancellation of critical flight. We have used the SEIR model to simulate the infection across the network of 6977 airports and 67663 flights. We have tested different flight cancellation strategies to limit the spread of infection. The number of infected airports after applying these cancellation strategies is used as a parameter to rank the strategies.

Estimation of Probable Health Losses in Biological Attack with Non-Contagious Agents, by Mathematical Epidemiology

STRATEGIES XXI: The Complex and Dynamic Nature of the Security Environment

In the case of attack with CBRN Weapons of Mass Destruction, the use of biological warfare agents is likely to amplify the effect on the living force, in order to infect, lethal or nonlethal, as many enemy as possible. The military medical service must be able to prevent, diagnose, treat and recover all affected military and the civilian population in the area. Health losses must be recovered in their entirety. Mathematical modeling of the epidemic induced by biological attack is useful for planning the forces and means of the military medical service, for medical planning the offensive or defensive operation, logistics and human resources needed for medical support and replacement. The estimates resulting from the calculations according to the formulas recommended in the specific NATO documents allow the optimization of the medical and non-medical countermeasures for the liquidation of the consequences of the biological attack.
