Abstract
This paper presents a prey–predator harvesting model with time delay for bifurcation analysis. We consider the parameters of the proposed model with imprecise data as form of interval in nature, due to the lack of precise numerical information of the biological parameters such as prey population growth rate and predator population decay rate. The proposed prey–predator harvesting model is presented with Holling type of predation and time delay under impreciseness of parameters by introducing parametric functional form of interval number. Our study reveals that along with delay and harvesting efforts role on the stability of the system, interval parameters also play a significant role. Computer simulations of numerical examples are given to explain our proposed imprecise model and for observing of chaotic behaviors.
