We carry out extensive Monte Carlo simulations of the three-dimensional (3D)uniformly frustrated XY model with uncorrelated randomly perturbed couplings,as a model for the equilibrium behavior of an extreme type-II superconductorwith quenched uncorrelated random point vortex pinning, in the presence of auniform applied magnetic field. We map out the resulting phase diagram as afunction of temperature T and pinning strength p for a fixed value of thevortex line density. At low p we find a sharp first order vortex latticemelting phase boundary separating a vortex lattice from a vortex liquid. As pincreases, it appears that this first order transition smears out over a finitetemperature interval, due to the effects of the random pinning, in agreementwith several recent experiments. At large p we find a second order transitionfrom vortex liquid to vortex glass.
