Simulaatiokello

Simulaatiokello, also known as a simulation clock or virtual clock, is a concept used in discrete event simulation. It is a variable that represents the current simulated time within a simulation model. Unlike real-world clocks that measure continuous time, a simulation clock advances in discrete steps, driven by the occurrence of simulated events.

The simulation clock is crucial for managing the progression of events and maintaining the correct chronological order of actions within the simulation. When an event occurs, the simulation clock is updated to the time of that event. The simulation then proceeds to process the event and schedule any new future events. This event-driven approach ensures that the simulation accurately reflects the temporal relationships between different parts of the modeled system.

The implementation of a simulation clock can vary depending on the simulation software or framework used. However, the fundamental principle remains the same: to keep track of simulated time and advance it based on event occurrences. The accuracy and efficiency of the simulation clock are vital for the overall performance and validity of the simulation results. Different simulation systems employ various techniques to manage the simulation clock, such as event lists and scheduling mechanisms, to ensure that events are processed in the correct order and that simulated time progresses logically. The concept of a simulation clock is foundational to understanding and building discrete event simulation models across various domains.
