Dynamical Analysis of an Exploited Prey-Predator System in Fuzzy Environment

Kunal Das, T.K. Kar

Abstract



Understanding the uncertainty in nature is a significant factor for an ecosystem. Considering this impreciseness we present the dynamics of an exploited prey-predator model in fuzzy environment. Here the uncertainty is considered in the growth and harvesting terms. The concept of fuzzy mathematics is incorporated and the concerned terms are modified using trapezoidal fuzzy number (TrFN). The dynamical behaviour of the system is studied extensively. Some numerical simulations are carried out.

Keywords


Prey-predator; Trapezoidal fuzzy number; Harvesting; Global stability.
