The quantum hydrodynamic model for electrons and ions and the generalized hydrodynamic model for the strongly coupled dust particles are proposed in the strongly coupled quantum dusty plasma,where the combined quantum effects of quantum diffraction,quantum statistic pressure,as well as electron exchange and correlation effects are all considered in the quantum hydrodynamic model.The shear and bulk viscosity effects are included in the viscoelastic relaxation,which leads to the decay of the dust-ion-acoustic waves.The approximate time-dependent solitary solution is obtained by the momentum conservation law in the presence of viscosity.
