The difference between the transportation and assignment
problems is that - answer each supply and demand value is 1 in the
assignment problem
In comparing different policies using simulation, one should use the
same set of random numbers whenever possible. - answer True
A quantity that is difficult to measure with certainty is called a -
answer probabilistic input
Models with a finite calling population - answer Use the size of the
population as parameter in the operating characteristics formulas
The number of units expected to be sold is uniformly distributed
between 300 and 500. If r is a random number between 0 and 1,
then the proper expression for sales is - answer 300 + r(200)
In an all-integer linear program, - answer all variables must be
integer.
Blending problems arise whenever a manager must decide how to -
answer mix two or more resources to produce one or more products.
Revenue management methodology was originally developed for -
answer an airline.
, A transshipment problem is a generalization of the transportation
problem in which certain nodes are neither supply nodes nor
destination nodes. - answer True
A requirement that two 0-1 variables both be either in or out of a
solution together is a - answer corequisite constraint
Before waiting lines can be analyzed economically, the arrivals' cost
of waiting must be estimated. - answer True
If arrivals occur according to the Poisson distribution every 20
minutes, then which is NOT true? - answer λ = 20 arrivals per hour
Let A, B, and C be the amounts invested in companies A, B, and C. If
no more than 50% of the total investment can be in company B,
then - answer −.5A + .5B − .5C ≤ 0
Which of the following is the most useful contribution of integer
programming? - answer using 0-1 variables for modeling flexibility
Which of the following statements is INCORRECT regarding the
advantages of simulation? - answer Simulation guarantees an
optimal solution.
Simulation is a trial-and-error approach to problem solving. - answer
True
The classic assignment problem can be modeled as a 0-1 integer
program. - answer True
The composite unit in data envelopment analysis - answer All of the
alternatives are correct.
