1. A healthcare process simulation system, the system including: a user interface adapted to receive input from a user and adapted to provide output to the user; a database adapted to store at least one simulation model; a modeling component adapted to allow the user to generate a simulation model using the user interface, wherein the simulation model is stored in the database; and a simulation engine adapted to simulate a process based at least in part on the simulation model and input from the user through the user interface, and wherein the simulation engine is adapted to provide output about the simulation to the user through the user interface.
