Discrete Modeling and Simulation

Discrete M&S is the one which uses a model built in terms of logic and the simulation time is represented as a discrete variable. Discrete M&S is typically used in disciplines such as computer science, systems engineering, industrial engineering, operations research, business, civil engineering, and management science. This type of M&S is commonly refered to as Discrete Event Simulation.
