Vortex lattice melting in a dirty mesoscopic square superconducting plate is studied using the molecular dynamics (MD) method. We include an impurity potential in the MD method and investigate vortex number and impurity number dependences of the melting transition temperature. We find strong vortex number dependence and weak pinning potential dependence of the melting temperature.
