We consider the Vicsek-type self-organized hydrodynamic (SOH) model with random inputs. In the absence of random inputs, the SOH model was derived as a macroscopic limit from the Vicsek model. Considering the uncertainty, which is modeled by a random parameter and enters into the SOH model through the initial data, we perform the local sensitivity analysis to study the regularity with respect to the random parameter and the stability of solutions to the random SOH model.
