An emerging alternative focuses on that solve these systems deterministically, often by reformulating them as Markov chains . This approach offers distinct advantages for smaller systems or scenarios where exact precision is non-negotiable. The Core Problem: Why Numerical Methods?

Discrete Event Simulation (DES) is the industry standard for modeling systems where state changes occur at specific, distinct points in time—like customers arriving at a bank or parts moving through a factory line. While powerful, traditional DES relies on randomness and Monte Carlo methods, which can require thousands of runs to achieve high precision.

The shift from simulation to numerical solving involves several key techniques: Numerical Methods for Solving Discrete Event Systems
