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

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.

for many centuries there were important factors which the economies of the muslim empires developed increasingly. they applied economic procedures in production, investment, finance, taxation and property. they used to tax certain goods (for example: harvest), they charged interest on money lent, they signed contracts with merchants; they relied on a common currency, and they used checks as well as promissory notes. with the money collected by means of taxation, the government provided the needy with an income. in addition, trading networks covered huge distances, so far regions started to have contact and exchange goods. this trade network covered areas of asia, africa and europe.
