Question 1

Simulation models that are based on the generation of random numbers may fail to give the same solution in repeated use to any particular problem.

Accepted Answer

Simulation models that generate random numbers are inherently stochastic and therefore may produce different solutions each time they are applied to a problem.

Question 2

Simulation has numerous applications in modern business,but few of these are in the area of operations.

Accepted Answer

Simulation has numerous applications in the area of operations such as supply chain management, inventory control, production planning and scheduling, and quality management.

Question 3

The seven steps in the use of simulation include all EXCEPT which of the following?
A)Define the problem.
B)Construct a numerical model.
C)Introduce important variables associated with the problem.
D)Find the optimal solution.
E)Run the experiment.

Accepted Answer

The seven steps in the use of simulation include defining the problem, constructing a numerical model, introducing important variables associated with the problem, verifying and validating the model, running the experiment, analyzing the results, and implementing the optimal solution. Finding the optimal solution is not explicitly mentioned as one of the steps. The optimal solution is typically determined during the analysis phase, where different scenarios and decisions are evaluated based on the simulation results.
