Simulation is the imitation of the operation of a real-world process or system over time. The act of simulating something generally entails representing certain key characteristics or behaviours of a designated target system. Simulation is used in many contexts, including healthcare, emergency management, engineering, logistics, and military training.
In healthcare, simulations are used to train medical professionals in new procedures or to assess their skills in high-pressure situations. In emergency management, simulations are used to help plan for and respond to natural disasters and other large-scale emergencies. In engineering, simulations are used to test new designs and predict how systems will behave under different conditions. In logistics, simulations are used to optimize supply chains and assess the impact of disruptions. In military training, simulations are used to prepare soldiers for combat and familiarize them with new equipment.
