Abstract
This paper is devoted to the construction of an approximate solution for the random differential equation with an initial condition and defined on a partition of the time-interval. We employ a random mean value theorem to achieve our goals in this work. The implicit Runge–Kutta method is presented and the conditions for the mean square convergence are established. Finally, illustrative examples are included in which the main statistical properties such as the mean and the variance of the random approximate solution process are given. The closeness of the original and approximate solutions is measured in the sense of the L 2-norm on Banach space and with probability one.
