A mathematical and parametric study of epidemiological smoking model: a deterministic stability and optimality for solutions

Abstract

The qualitative study of a smoking model with parametric conditions for diseases controlling under the influence of smoking is investigated through rigorous mathematical study. The mathematical modeling of epidemiological smoking model having six compartments is traced out. Mathematical expressions for smoke-free and smoke-present equilibrium points have been developed. The strength of Lyapunov functional theory has been exploited to show that smoke-free equilibrium point is globally asymptotically stable whenever basic reproduction number $$R_\\circ <1$$ R ∘ < 1 . The competency of graphical and theoretic process is utilized to observe the global behavior of unique smoke equilibrium point. The sensitivity analysis of the model is performed through the basic reproduction number and diseased classes effectively to design reliable, robust and stable control strategies.
