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. Chapter 1 Introduction to Simulation Modeling
