When variables and parameters within differential equations are not defined exactly but are vague, imprecise or incomplete due to errors in measurement or other factors, one may use fuzzy environment in parameters, variables and initial conditions in place of crisp ones, turning the general differential equations into Fuzzy Differential Equations (FDEs). This book presents reliable and efficient numerical techniques for the solution of FDEs viz. fuzzy ordinary and partial, fuzzy linear and nonlinear and fuzzy arbitrary order differential equations.

Preliminaries of Fuzzy Set Theory. Basics Concepts of Fuzzy and Fuzzy Fractional Differential Equations. Analytical Methods of Fuzzy Differential Equations. Numerical Methods for Fuzzy Ordinary and Partial Differential Equations. Application of Numerical Methods to Fuzzy Ordinary Differential Equations. Fuzzy Structural Problems. Fuzzy Vibration Equation of Large Membrane. Non Probabilistic Uncertainty Analysis of Forest Fire Model. Fuzzy Inverse Heat Conduction Problems. Fuzzy Fractional Klein-Gordon Equation.
