Dispatcher-based simulation

In this method, a virtual version of a building is created on a computer, modeling passengers and elevators as realistically as possible, and random numbers are used to model probability rather than mathematical equations and percentage probability.

Dispatcher-based simulation has had major improvements over the years, but the principle remains the same. The most widely used simulator, Elevate, was first showcased in 1998 as Elevate Lite.

Although it is currently the most accurate method of modeling an elevator system, the method does have drawbacks. Unlike calculations, it does not find a RTT value because it does not run standard round trips; thus it does not conform with standardized elevator-traffic analysis methodology, and cannot be used to find values such as average interval; instead, it is generally used to find the average waiting time.
