Certain methods on numerical solutions of fuzzy and intuitionistic fuzzy initial value problems

Abstract

In many cases information about the behavior of a dynamical system newlineis uncertain In order to obtain a more realistic model all uncertainties should newlinebe taken into account Also in several cases the uncertainties are not of newlinestatistical type for having some linguistic information and when a newlinemeasurement cannot be repeated are such cases Fuzzy differential equations newlineFDEs are a natural way to model dynamical systems under possibilistic newlineuncertainty Also in modeling real world phenomena fuzzy initial value newlineproblems FIVPs appear naturally There will be times when solving the newlineexact solution may be unavailable or the means to solve it will be unavailable newlineand therefore it is indispensable to make studies on numerical solutions of newlineFDEs newline newline
