What are some characteristics of simulation models? - correct
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
answer✔✔1. Discrete (vs. continuous) ||\\||\\ ||\\||\\ ||\\||\\
2. Stochastic (vs. deterministic)
||\\||\\ ||\\||\\ ||\\||\\
3. Dynamic (vs. static)
||\\||\\ ||\\||\\ ||\\||\\
What is simulation? - correct answer✔✔Simulation is the
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
imitation of a real-world process of system over time. ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
Simulation involves the generation of an artificial history to ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
draw inferences concerning the operating characteristics of the
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
real system that is represented.
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
What is simulation good for? - correct answer✔✔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
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
,What are the reasons to simulate? - correct answer✔✔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
||\\||\\ ||\\||\\ ||\\||\\
What are the advantages of simulation? - correct answer✔✔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
||\\||\\ ||\\||\\ ||\\||\\
, What are the disadvantages of simulation? - correct||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
answer✔✔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
We are interested in modeling the arrival and service process at
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
the local McBurger Queen burger joint. Customers come in
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
every once in a while, stand in line, eventually get served, and
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
off they go. Generally speaking, what kind of model are we
