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- Correct answer
-(a) (because events such as arrivals and service completionshappen
only
oncein a while,as opposedto continuously);and (c) (becausecustomerarrival times,servicetimes, shift
changes, etc., are all random
).
Which of the followingcan be regardedas advantagesof simulation? (More than one answerbelowmay be
right.)
A) Simulationenablesyouto studymodelstoocomplicatedfor analyticalor numericaltreatment.
B) Simulationscan serveas veryprettydemosthatevenUniversityof Georgiagraduatescan
understand.
C) Simulationcan be usedto studydetailedrelationsthatmight be lost in an analyticalor numerical
treatment.
D) Simulationsareoftentediousand time-consumingto produce.- Correct answer-A) Simulation
, enables you to study models too complicated for analytical or numerical treatment.
