Simulation and modelling are essential to system engineering. They are effective instruments for designing, evaluating, and optimising complex systems before they are constructed or put into use. The conception and design of systems are aided by modelling and simulation. They let engineers to examine various configurations, designs, and parts by building virtual models of the system. Engineers are able to evaluate the viability, performance, and reliability of alternative design solutions by modelling the system's behaviour and interactions. Models and simulations aid in assessing a system's performance characteristics. Engineers may examine how the system responds to various input situations, operating scenarios, and stress variables. Early in the development process, possible bottlenecks, weaknesses, or places for improvement might be found thanks to this study. System engineering requires the use of modelling and simulation extensively. They provide engineers the capacity to create, examine, enhance, and verify systems, which boosts efficiency, dependability, and performance. System engineers may shorten development time, minimise costs, and limit hazards related to complex systems by efficiently using these techniques.
