simulation - ANS>>using computer techniques to simulate world facility or process (the
system)
model - ANS>>mathematical or logical representation of system behavior
discrete system - ANS>>state variables change at separate point in time
continuous system - ANS>>state variables change continuously with time
event - ANS>>An instantaneous occurrence that may change the system's state
T or F? Most complex systems are composed of a set of queue-servers interacting with
each other. - ANS>>True
T or F? For a discrete event simulation model, state variable change continuously with
time. - ANS>>False
T or F? As a patient, your doctor leaving you to minister to a much more critically hurt
patient is an example of pre-emption. - ANS>>True
T or F? As we increase the number of replications for our model, the confidence interval
range should become wider. - ANS>>False
T or F? Variables are pieces of information that are entity-specific. - ANS>>False
T or F? For a queue, it is not possible to express a performance measure as a
mathematical function of input parameters. - ANS>>False
T or F? Randomness has a significant impact on system performance. - ANS>>True
T or F? Replacing a probability distribution by its mean will give us a more accurate
understanding of system performance - ANS>>False
T or F? Standard metrics of interest in a simulation model include utilization rate of
service resources and average time in queue for clients - ANS>>True
T or F? We prefer our random variables to have a large variance. - ANS>>False
T or F? Within a simulation software package, we should be able to represent each
source of randomness with a probability distribution. - ANS>>True
