Simulaatiomallinnus, or simulation modeling in English, is a technique used to imitate the behavior of real-world systems over time. It involves creating a computer-based model that represents the key components and processes of a system. This model can then be used to run experiments, analyze scenarios, and predict outcomes without directly interacting with the actual system.

The purpose of simulation modeling is to gain a deeper understanding of how a system works, to identify potential problems or bottlenecks, and to evaluate the effectiveness of different strategies or designs. This can be applied to a wide range of fields, including engineering, economics, environmental science, and healthcare. For instance, engineers might use simulation to test the performance of a new aircraft design, while urban planners might use it to model traffic flow in a city.

There are various types of simulation models, such as discrete-event simulation, agent-based modeling, and system dynamics. Discrete-event simulation focuses on systems where changes occur at specific points in time, like customers arriving at a service desk. Agent-based modeling simulates the actions and interactions of individual autonomous agents within an environment. System dynamics, on the other hand, models systems with feedback loops and continuous flows, often used for long-term strategic planning.

Building a simulation model typically involves defining the system's components, their attributes, and the rules governing their interactions. Data collection and validation are crucial steps to ensure the model accurately reflects reality. Once built and validated, the model can be run multiple times with different input parameters or conditions to explore various "what-if" scenarios. The results from these simulations provide insights that can inform decision-making and improve system performance.
