Simulation is a multi-disciplinary field with the objective of representing and reproducing the behaviour of a system or a phenomenon. This subject will expose students to a variety of simulation methods. By concluding this subject, students would learn the impact of representation on simulation outcomes, types of simulations, the role and importance of random numbers, the basic Monte Carlo simulation method, discrete event vs discrete time simulation, continuous process simulation, the three phase method, system dynamics simulation, agent-based simulations, how to analyse simulation data and how to use simulation for system level optimisation.
