Numerical Solution of Poisson Equation Using Fuzzy Data by finite Difference

Abstract

In this paper, we have discussed fuzzification of elliptic partial differential equation taking Poisson Equation in two dimensions are discussed. The interval of fuzzy interval can be determined. Finite difference method applied of two different grids using five points, first for initial values and the second to solve Poisson equation numerically.

Keywords: Fuzzy membership function (f.m.f.), interval of confidence, triangular fuzzy number (t.f.n.), cuts, five points finite difference, Poisson Equation.
