GRADED A+ (BRAND NEW VERSION!!)

• **What are some characteristics of simulation models?**

**ANSWER:**

• Discrete (vs. continuous)
• Stochastic (vs. deterministic)
• Dynamic (vs. static)

• **What is simulation?**

**ANSWER:** Simulation is the imitation of a real-world

process or system over time. It 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?**

**ANSWER:**

• Describe/analyze real or conceptual system behavior

• | P a g e

• Ask "what if" questions
• Aid in system design and optimization
• Can simulate almost anything

• **What are the reasons to simulate?**

**ANSWER:**

• Will the system accomplish its goals?
• Current system won’t accomplish its goals, now what?
• Need incremental improvement
• Create a specification or action plan
• Solve a problem, like a bottleneck
• Resolve disputes
• Sell an idea

• **What are the advantages of simulation?**

**ANSWER:**

• Can study models too complicated for analytical/numerical

treatment

• Study detailed relations that might be lost in analytical or

numerical treatment

• | P a g e

• Use as a basis for experimental studies of systems
• Use to check results and give credibility to conclusions

obtained by other methods

• Reduce design blunders
• Really nice demo method
• (Sometimes) very easy

• **What are the disadvantages of simulation?**

**ANSWER:**

• Sometimes not so easy
• Sometimes very time-consuming/costly
• Simulations give "random" output (and lots of

misinterpretation of results is possible)

• 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

• | P a g e

are we talking about here? (More than one ANSWER may be right.)**

• Discrete
• Continuous
• Stochastic
• Deterministic

**ANSWER:** A) Discrete and C) Stochastic

**Explanation:** A) Discrete because events (arrivals, service

completions) happen intermittently, not continuously; C) Stochastic because customer arrival times, service times, etc., are random

• **Which of the following can be regarded as advantages of

simulation? (More than one ANSWER may be right.)**

• Simulation enables you to study models too complicated

for analytical or numerical treatment

• Simulations can serve as very pretty demos that even

University of Georgia graduates can understand

• Simulation can be used to study detailed relations that

might be lost in an analytical or numerical treatment

• Simulations are often tedious and time-consuming to

produce

**ANSWER:**
