There are many models being used. Those which have a large component of simulation through out the curriculum have a simulation coordinator/director. Many also have other staff to support the simulation efforts. The others often do the scheduling, ordering supplies,set-up and take-down. Many have a full-time assistant with responsibilities to 'run' the high-fidelity simulators during scenarios so faculty can concentrate on facilitating the eseeions and working with the students. AT BYU, we hire students to run the simulator (they take to the 'computer' very easily) and they also assist in set-up and take-down.
