This paper studies the effect of time delay and proportional harvesting on stability of mutualism model as well as to establish conditions for sustainable harvesting so that the unique positive equilibrium point is stable. First the stability of the model with harvesting is analyzed. The model is then improved by considering a time delay in the mechanism of(More)
In epidemiology, the classic Susceptible-Infective-Removed (SIR) model is often used to give a simple representation of the spread of an infectious disease. There are two parameters involved, namely the transmission rate and the removal rate. Identifying these parameters is crucial in modeling any infectious disease because they indicate the severity of the(More)
