10. Typical Uses of Simulation • Estimating a set of productivity measures in production systems, inventory systems, manufacturing processes, materials handling and logistics operations. • Designing and planning the capacity of computer systems and communication networks so as to minimize response times. • Conducting war games to train military personnel or to evaluate the efficacy of proposed military operations • Evaluating and improving maritime port operations, such as container ports or bulk-material marine terminals (coal, oil or minerals), so as to find ways of reducing vessel port times. • Improving health care operations, financial and banking operations, transportation systems and airports, among many others.
