Discreetevent

Discreetevent refers to a simulation modeling technique where changes in the system state occur only at discrete points in time. These points are called "events." Instead of continuously tracking the system's behavior over time, a discrete-event simulation focuses on the transitions between these defined events. A typical discrete-event simulation proceeds by maintaining a list of future events, ordered by their scheduled time. The simulation clock advances to the time of the next event, and the system state is updated accordingly. Once the event is processed, new future events might be scheduled, or existing ones modified. This cycle repeats until a termination condition is met. This approach is widely used in various fields such as manufacturing, logistics, telecommunications, and healthcare to analyze complex systems, evaluate different scenarios, and optimize performance. It allows for the study of systems where interactions are not continuous but rather occur as distinct occurrences, like a customer arriving at a store, a machine completing a task, or a message being sent. The core components of a discrete-event simulation are the system state, simulation clock, event list, event routines, and statistics collection.
