An anisotropic model with variableG and Λ and bulk viscosity is considered. The model exhibits an inflationary behavior during which the coefficient of bulk viscosity varies lineraly with the energy density. This allows the anisotropy energy to decrease exponentially with time. Other results overlap with our earlier work with a different ansatz for Λ. The gravitational ‘constant’ was found to increase during the radiation and matter epochs.
