Group A
Attempt Two Questions(2 × 10 = 20)
- 1.10
Define queuing system. Explain the Kendall's notation for queuing system? What are the various performance measures in single server queuing System? Explain which of them determine system stability and how?
- 2.10
Define true random numbers and pseudo random numbers with its properties . The sequence of numbers 0.64, 0.50, 0.25, 0.58,0.72, 0.90 has been generated. Use KS Test with Da=0.050 => 0512 to determine if the hypothesis that they are uniformly distributed on interval [o, 1] can be rejected.
- 3.10

- 9.5
Why is estimation methods used in simulation? Explain.
- 10.5
Explain the importance of elimination of initial bias during simulation.
- 11.5
Workers come to a supply store at the rate of one every 6(+-) 2 minute. Their requisitions are processed by one of the two clerks who take 8 (+-) 2 minutes for each requisition. The requisitions are then passed to a single storekeeper who fills them one at a time, taking 6(+-)3 minutes for each. Draw GPSS Block diagram to simulate The above problem for 100 requisitions.
- 12.5

a. Digital analog simulator
b. Simulation tools
