Simulation modeling is a technique used to create a digital representation of a real-world process or system. By using mathematical formulas and algorithms, it allows researchers and decision-makers to analyze how different variables interact over time. This helps in understanding complex systems, predicting outcomes, and testing scenarios without the risks or costs associated with real-life experimentation. In various fields such as engineering, healthcare, and business, simulation modeling can optimize operations, improve efficiency, and enhance decision-making. It provides valuable insights by visualizing potential changes and their impacts, making it a powerful tool for planning and strategy development.
