What is simulation? Simulation is the imitation of some real thing or process. Simulation has become a key method of research and development due to its cost advantages over the real scenario. The IT industry has revolutionized the way we simulate. Simulation models can be developed in three ways: first by useng programming languages like C,C++ & Java; second by using advanced softwares like Arena, GPSS & SIMAN; third by developing simulation environment. » Read more: Simulation and Future
