ISYE6644 (Simulation) Midterm 1 Questions
1.What are some characteristics of simulation models?: 1. Discrete (vs.
contin- uous)
2.Stochastic (vs. deterministic)
3.Dynamic (vs. static)
2.What is simulation?: Simulation is the imitation of a real-world process
of system over time.
Simulation involves the generation of an artificial history to draw
inferences concern- ing the operating characteristics of the real system
that is represented.
3.What is simulation good for?: 1. Describe / analyze real or conceptual
system behavior.
2.Ask "what if" questions.
3.Aid in system design and optimization
4.Can simulate almost anything
4. What are the reasons to simulate?: 1. Will the system accomplish its
goals?
2.Current system won't accomplish its goals, now what?
3.Need incremental improvement.
4.Create a specification or action plan
5.Solve a problem, like a bottleneck.
6.Resolve disputes
7.Sell an idea
5. What are the advantages of simulation?: 1. Can study models too
complicated for analytical / numerical treatment
2.Study detailed relations that might be lost in the analytical or numerical
treatment
3.Use as a basis for experimental studies of systems
4.Use to check results and give credibility to conclusions obtained by
other methods.
5.Reduce design blunders
6.Really nice demo method
7.(sometimes) very easy
6. What are the disadvantages of simulation?: 1. Sometimes not so easy
2.Sometimes very time consuming / costly
3.Simulations give "random" output (and lots of misinterpretation
of results is possible)
4.To do a certain problem, better methods than simulation may exist
