ABSTRACT
The use of computers to simulate the behavior of physical or natural systems is as old as the history of computers itself. Adaptation of physical simulators, such as the original mechanical pilot training simulators, to real-time computer-based simulators was another early development in computer applications. Although the main focus here is on real-time simulation with hybrid models (explained below), the topic of simulation using hybrid models in general will be addressed first, with a more specific treatment of real-time applications introduced later.
