This paper is devoted to the study of the role of particle creation and bulk viscosity in the evolution of the homogeneous and anisotropic model of the universe represented by Bianchi type I space-time metric in Brans-Dicke theory. Particle creation and bulk viscosity have been considered as separated irreversible processes. In order to discuss the physical and geometrical behaviour of the model, a new set of exact solutions of field equations have been obtained in non-causal, truncated and full causal theories. The dynamical behaviours of models have also been discussed.
