Abstract
In the present paper, the expansion of Locally Rotational Symmetric (LRS) Bianchi type - I cosmological model have been investigated with Bulk Viscous matter in the context of theory of gravity, where signifies the torsion scalar. The power model, exponential model and linear functional model of the universe have been discussed for choices of with utilization of the special form of time dependent varying deceleration parameter. The discussion involves the examination of the dynamical behaviour of these models using some dynamical parameters and its graphical representation.
