Modeling and Simulation (all correctly done)

system correct answers a combination of components that act together to perform a function not possible with any of the individual components. model correct answers a physical, mathematical or otherwise logical representation of a system, entity, phenomenon or process. simulation correct answers a method for executing a model to extract data concerning model behavior visualization correct answers the use of computer graphics and visual techniques to provide a visual representation of simulation-related information analysis correct answers the use of mathematically based techniques to obtain information from data and to arrive at a good or optimal decisions in complex situations modeling and simulation correct answers the use of models and simulations, combined with analysis and visualization, to develop information for managerial or technical decisions and/or for training stochastic models correct answers many models contain parameters that are described by random variables; simulation of these models results in outputs that are so also random variables; analysis of these systems requires the application of concepts from the area of mathematics called probability and statistics Why is the importance of stochastic models to M&S? correct answers (1) generation of random numbers and random variates; (2) statistical modeling of simulation input data; (3) statistical modeling of simulation output data; (4) techniques to enhance precision and confidence for a given number of trial runs Why are humans important in M&S? correct answers most simulations are designed to interface with a human user at some point in the M&S process; many complex systems contain humans as system components; the use of M&S to study complex systems requires an understanding of how to interface with and represent humans human factors (HF) correct answers knowledge of human cognition and perception; basics of how to interface effectively with humans human/computer interfacing (HCI) correct answers study of how to design effective and efficient interfaces between a computer simulation and a human operator human behavior modeling (HBM) correct answers study of how to model computationally the process of human decision making
