Simulation systems include discrete event simulation, process simulation and dynamic simulation. Businesses may use all of these systems across different levels of the organisation. The model represents the key behaviours and characteristics of the selected process or system while the simulation represents how the model evolves under different conditions over time. time.
Simulations are usually computer-based, using a software-generated model to provide support for the decisions of managers and engineers as well as for training purposes. Simulation techniques aid understanding and experimentation, as the models are both visual and interactive. Simulation systems include discrete event simulation, process simulation and dynamic simulation. Businesses may use all of these systems across different levels of the organisation. This chapter highlights simulation models of water resource systems (WRS). The advances in computer techniques have created the possibility to construct models of large-scale and complex systems. The use of simulation models employing digital computers is the basic technique for modeling these systems. In WRS design, simulation refers to a modeling technique in which the operation of the WRS is represented by mathematical and logical relationships in a chosen time step based on specific inputs, capital costs of hydroelectric power plants, capacities of diversion tunnels, and on some predetermined operational policy. A simulation model describes the relationships
