A class of efficient and robust methods which includes the classical spitting methods, alternating direction schemes and fractional step Runge-Kutta methods used to discretize efficiently some linear parabolic problems is studied. The coefficients of these parabolic problems depend on time. Such analysis was performed by suitably decomposing the contribution to the global error of this time integration procedure and the contribution of some standard spatial discretization methods.
