Mathematics is a vast and diverse field, encompassing a wide range of topics such as numbers, formulas, shapes, and quantities. One particular area of mathematics that has gained significant attention in recent years is discrete event simulation (DES). This powerful tool helps mathematicians, engineers, and researchers to model and analyze complex systems that involve stochastic and dynamic processes. But what exactly is discrete event simulation? In simple terms, it is a computational technique used to model and analyze the behavior of a system over time by tracking individual events and their occurrence.
