What is the purpose of model simulation?

Model simulation is a tool used to analyze the behavior of complex systems. It can be used to predict the effects of changes in the system, identify potential problems, and explore possible solutions. Simulation can also be used to identify patterns, trends, and relationships in data. It can be used to optimize designs, test theories, and gain insights into the behavior of a system.

"The purpose of a simulation is to gain system understanding without manipulating the real system, either because it is not yet defined or available, or because it cannot be accessed directly due to cost, time, resources or risk constraints " -Simplifying Complexity Through Model Based Systems Engineering
