Ecological system depends on prey predator interaction. Sometimes diseases are spread
among prey or predator or both species. In this paper, a disease control prey–predator …

This study considers the classical Lotka–Volterra model for a prey–predator system with
harvesting effort and catchability coefficients for both species incorporating a new prey …

In this article, we have solved the type-2 fuzzy differential equation. The nonlinear type-2
triangular fuzzy numbers (NT2TFNs) are taken, and their different arithmetic properties are …

The strategy applied in this study is fuzzy logic based decision-making system to achieve a
rapid way to assess block-toppling failure instability in discontinuous rock slopes as justified …

Parameters involve in various ecological models are mostly uncertain due to ever changing
characteristic of nature. This article, deals with a basic predator–prey model where …

In this paper a fuzzy logistic equation with alley effect is introduced by considering some
parameter as fuzzy numbers. Due to presence of the fuzzy number the corresponding …

In this paper we study the application of ordinary differential equation in Glucose-Insulin
Regulatory system modeling which is considered in fuzzy environment. The solution strategy …

The fuzziness of the parameters of any mathematical model is a major concern today in the
field of epidemiology. In this article we apply the technique of Hukuhara derivative for …

The key objective of this paper is to study the imprecise biological complexities in the
interaction of two species pertaining to harvesting threshold. It is explained by taking the …

In this paper, we construct a tritrophic level food chain model considering the model
parameters as fuzzy interval numbers. We check the positivity and boundedness of solutions …
