چکیده
|
Fuzzy integral equations is a mathematical tool for modeling the uncertain control system and economic. in this paper, we present numerical solution of nonlinear fuzzy volterra integral equations(nfvies) using successive approximations scheme and block-pulse functions. additionally, the convergence analysis of the presented approach is investigated involving lipschitz and several conditions and error bound between the approximate and the exact solution is provided. finally, to approve the outcomes concerned with the theory a numerical experiment is considered.
