The segment implicit scheme of finite difference approximation is constructed with the aid of Saulyev asymmetric schemes. Then a new alternating segment explicit-implicit method for the diffusion equation is developed, which is suitable for the computation on parallel and vector computers. The method is unconditionally stable and also gives more accurate solutions because of its better truncation error. In the numerical experiments for an example the accuracy of the method is compared with that of the AGE method (Evans and Abdullah).
