Chapter 18S - Supplement Simulation Chapter 18S Supplement Simulation True / False Questions 1. Simulation is generally run until we find the optimal solution to a problem. FALSE Difficulty: Medium TLO: 4 Taxonomy: Knowledge 2. Simulation is basically a technique used to find an optimal solution recognizing the constraints of the problem solution. FALSE Difficulty: Medium TLO: 1 Taxonomy: Knowledge 3. Simulation models once built are fairly easy to use and understand; therefore they can be used for a wide range of decisions. TRUE Difficulty: Easy TLO: 4 Taxonomy: Knowledge 4. If a situation is too complex to solve mathematically, simulation might help. TRUE Difficulty: Easy TLO: 2 Taxonomy: Knowledge 18-1

Chapter 18S - Supplement Simulation 5. To validate a simulation, first the simulation is run, then the actual system is changed to see if the simulation is valid. FALSE Difficulty: Medium TLO: 6 Taxonomy: Knowledge 6. A simulation model is validated if it adequately approximates the real system performance. TRUE Difficulty: Easy TLO: 6 Taxonomy: Knowledge 7. The purpose of running experiments on a simulation model is to answer "what if" questions. TRUE Difficulty: Medium TLO: 6 Taxonomy: Knowledge 8. Monte Carlo simulations, developed in Europe in the mid-1950's, are deterministic. FALSE Difficulty: Medium TLO: 1 Taxonomy: Knowledge 9. A Monte Carlo simulation implies that randomness has been incorporated in the simulation. TRUE Difficulty: Easy TLO: 1 Taxonomy: Knowledge 18-2
Chapter 18S - Supplement Simulation 10. When using a random number table, it is important to always start at the same point of the table so that results may be replicated. FALSE Difficulty: Easy TLO: 3 Taxonomy: Knowledge 11. Two important features of the sets of random numbers are that the numbers are uniformly distributed and there should be no discernable patterns. TRUE Difficulty: Medium TLO: 3 Taxonomy: Knowledge 12. In probabilistic simulations, a single simulation run should be regarded as a sample. TRUE Difficulty: Medium TLO: 5 Taxonomy: Knowledge 13. A normal distribution has a mean of 9 and a standard deviation of 2. The random number +1.00 has been drawn from a table of normally distributed random numbers. The simulated number is therefore 10 (9+1). FALSE AACSB: AS Difficulty: Hard TLO: 6 Taxonomy: Application 18-3

Chapter 18S - Supplement Simulation 14. A uniform distribution has end points of 40 and 90. A random number of 20 from a two- digit random number table equates to a simulated value of 50. TRUE AACSB: AS Difficulty: Hard TLO: 6 Taxonomy: Application 15. When simulating numbers for an exponential distribution, a table of uniformly distributed random numbers can be used. TRUE
