Discrete event simulation simulates the flow of materials, components, and finished products through a production facility to analyze bottlenecks and explore ways to optimize production in a risk-free virtual environment.
A discrete event simulation models a process where actions or procedures along the chain of events change the system in only one degree. That could be, for instance, a conveyor belt junction sending an object one way or another or a robot applying a screw or bolt where there wasn’t one before.
Discrete event simulation assumes that there is no change in state between a departure event and the following arrival event, so it models the behavior or process of a workflow in a compressed time and form for fast and accurate analysis.
Those analyses might predict performance results, discovering the variables resulting from the interaction between events or statistical modeling.
