## Fifth Semester | Third Year | Tribhuvan University Old Question Collection | Question Bank Simulation and Modeling, Year: 2069 Computer Science and Information Technology (CSc. 302) Full Marks: 60 | Pass Marks: 24 | Time: 3 hours

Candidates are required to give their answer in their own words as far as practicable.
The figures in the margin indicate full marks.

Group A
Attempt any two questions. (2×10=20)

1. Define simulation. What are the various steps in simulation study? Explain.
2. Explain Markov Chains with example.
3. What are the properties of random number? The sequence of numbers 0.54, 0.73, 0.98, 0.11 and 0.68 has been generated. Use the Kolmogorov – Smirnov test α = 0.05 to determine if the hypothesis that the numbers are uniformly distributed on the interval 0 to 1 can be rejected. (Note that the critical value of D for α = 0.05 and N = 5 is 0.565).
Group B
Attempt any eight questions. (8×5=40)
4. When is simulation appropriate and when it is not?
5. What do you mean by server utilization?
6. What do you mean by non-uniform random number?
7. Why an auto-correlation test is needed in random number?
8. What do you mean by calibration and validation?
9. When is estimation method appropriate? Explain.
10. Explain Hybrid simulation with example.
11. Use the multiplicative congruential method to generate a sequence of four three-digit random numbers. Let r0 = 118, a = 4 and m = 1000.
12. Explain the distributed lag model.
13. Write short notes on:
a) Queuing discipline
b) CSMP
