MODELING AND SIMULATION QUESTIONS WITH CORRECT ANSWERS

system CORRECT ANSWER a combination of components that act together to perform a function not possible with any of the individual components. model CORRECT ANSWER a physical, mathematical or otherwise logical representation of a system, entity, phenomenon or process. simulation CORRECT ANSWER a method for executing a model to extract data concerning model behavior visualization CORRECT ANSWER the use of computer graphics and visual techniques to provide a visual representation of simulation-related information analysis CORRECT ANSWER 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 ANSWER 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 ANSWER 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 ANSWER (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 ANSWER 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
