Chapter 1. Introduction to Discrete Event Simulation Engineering

The Event Graph (EG) diagrams of Schruben (1983) allow defining computationally complete process design models for event-based simulation, which can be viewed as the most fundamental Discrete Event Simulation (DES) paradigm. In these diagrams, circles represent event types, and arrows between two event type circles A and B represent event scheduling with a future events list in the sense that an occurrence of an event of type A in a simulation run causes the simulator to schedule a future event of type B.
