This study introduces a method to predict and prevent large epidemic outbreaks by analyzing noise effects. The adaptive control scheme ensures stability in stochastic processes with deterministic structures.

Area of Science:

  • Epidemiology
  • Stochastic Processes
  • Control Theory

Background:

  • Epidemic outbreaks can occur randomly, influenced by various stochastic factors.
  • Understanding the impact of noise is crucial for predicting and managing disease spread.
  • Existing models may not fully capture the dynamics of random outbreak occurrences.

Purpose of the Study:

  • To investigate the effects of noise on a model of randomly occurring epidemic outbreaks.
  • To develop an adaptive control scheme for preventing large-scale epidemics.
  • To establish the applicability of the derived theory to broader stochastic processes.

Main Methods:

  • Utilizing a constructive transition approach to predict potential large outbreaks.
  • Deriving an adaptive control scheme based on predictive modeling.
