To analyse the accuracy of the algorithm mentioned above, we construct the DEVSS scheme based on (10) and consider its discretization in the time domain within a typical time subinterval [[t.sub.n], [t.sub.n+1]], which give us the form of the Wilson-[theta] method as follows:

where [D.bar] is an added variable for constructing DEVSS scheme, 0 [less than or equal to] [theta], [[theta].sub.1], [[theta].sub.2], [[theta].sub.D], [[theta].sub.[tau]] [less than or equal to] 1.
