  In this article, the complete moment convergence for the partial sum of
moving average processes $\{X_n=\sum_{i=-\infty}^{\infty}a_iY_{i+n},n\ge 1\}$
is estabished under some proper conditions, where $\{Y_i,-\infty<i<\infty\}$ is
a sequence of $m$-widely acceptable ($m$-WA) random variables, which is
stochastically dominated by a random variable $Y$ in sub-linear expectations
space $(\Omega,\HH,\ee)$ and $\{a_i,-\infty<i<\infty\}$ is an absolutely
summable sequence of real numbers. The results extend the relevant results in
probability space to those under sub-linear expectations.
