Chapter 89: Simulation – Discrete Event
It is generally accepted that traditional planning methods and mathematical/analytical modelling techniques are not appropriate if detailed analysis is required for complex systems that consist of many discrete operations that occur randomly and non-linearly for mathematical models or other methods to be practical. Simulation modelling in the form of discrete-event simulation (DES) has evolved to become one of the most popular and cost-effective means of analysing complex systems. Discrete-event simulation is a simulation in which the state of a model changes at only a discrete, but possibly random, set of simulated points in time.
Business processes and operations include events that occur at discrete times as a result of other events. Therefore, computer-based simulation is an essential ...
