According to Gilbert and Troitzsch (2005), foundations of Simulation Modeling, a simulation model is a computer program that captures the behavior of a real-world system and its input and possible output processes. Simulation modeling relies upon what

Answer: Data from real world

Explanation:

According to the concept created by Gilbert and Troitzsch in 2005 on simulation model which was less complex, low detailed, precise, easy and smaller as a system. This model took input from real world for extracting certain output accordingly.

Thus simulation model was dependent upon data that it received from real worlds as the complete process of input ant output was based on it. It created artificial data that was imitation of the original data so that experiments can be conducted on it.
