Using discrete-event simulation to model human performance in complex systems

System performance is often determined by the performance of the humans in the system. Yet, system models often leave out any significant representation of the humans that are operating and maintaining them. Recently, tools and methods for modeling the human in systems have begun to receive widespread attention. These tools and methods are consistent with other types of models and simulations that are used to model other system components. In this paper, the basic approaches to modeling human performance are discussed along with a brief case study
