Latest Edition.
What |are |some |characteristics |of |simulation |models? |- |ANS |-1. |Discrete |(vs. |continuous)
2. |Stochastic |(vs. |deterministic)
3. |Dynamic |(vs. |static)
What |is |simulation? |- |ANS |-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? |- |ANS |-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? |- |ANS |-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? |- |ANS |-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? |- |ANS |-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 |talking |about |here? |(More |
than |one |answer |below |may |be |right.)
A) |Discrete
B) |Continuous
C) |Stochastic
D) |Deterministic |- |ANS |-(a) |(because |events |such |as |arrivals |and |service |completions |only |
happen |once |in |a |while, |as |opposed |to |continuously); |and |(c) |(because |customer |arrival |times,
|service |times, |shift |changes, |etc., |are |all |random).
, Which |of |the |following |can |be |regarded |as |advantages |of |simulation? |(More |than |one |answer |
below |may |be |right.)
A) |Simulation |enables |you |to |study |models |too |complicated |for |analytical |or |numerical |
treatment.
B) |Simulations |can |serve |as |very |pretty |demos |that |even |University |of |Georgia |graduates |can |
understand.
C) |Simulation |can |be |used |to |study |detailed |relations |that |might |be |lost |in |an |analytical |or |
numerical |treatment.
D) |Simulations |are |often |tedious |and |time-consuming |to |produce. |- |ANS |-A) |Simulation |
enables |you |to |study |models |too |complicated |for |analytical |or |numerical |treatment.

Who |is |William |Gosset?
A) |He |invented |the |t |distribution |that |is |used |ubiquitously |in |statistics.
B) |He |invented |the |s |distribution |that |is |used |ubiquitously |in |statistics.
C) |He |invented |tea.
D) |He |invented |the |word |"ubiquitous".
E) |He |is |the |brother |of |Louis |Gossett |Jr., |best |known |for |his |fine |acting |in |many |films, |including
|An |Officer |and |a |Gentleman. |- |ANS |-A) |He |invented |the |t |distribution |that |is |used |ubiquitously
|in |statistics.
What |was |the |first |use |of |a |computer |simulation? |- |ANS |-Stan |Ulam |and |Johnny |von |Neumann
|in |1946 |after |world |war |2. |They |used |simulation |in |the |context |of |the |development |of |the |H |
bomb.
