Where agents replace both human teams, the simulation can become fully computerised and can, with minimal supervision, run by itself. The main advantage of this is the ready accessibility of the simulation—beyond the time required to program and update the computer models, no special requirements are necessary. A fully computerised simulation can run at virtually any time and in almost any location, the only equipment needed being a laptop computer. There is no need to juggle schedules to suit busy participants, acquire suitable facilities and arrange for their use, or obtain security clearances. An additional important advantage is the ability to perform many hundreds or even thousands of iterations in the time that it would take a manual simulation to run once. This means statistical information can be gleaned from such a model; outcomes can be quoted in terms of probabilities, and plans developed accordingly.
