Analysis of Simulation Output
1.
Why Confidence interval is needed in the analysis of simulation output. How can we establish a confidence interval? [5]
Introduction to Simulation
1.
Explain the Monte Carlo simulation method with example. [5]
2.
Describe dynamic physical model in detail with the help of suitable example. [5]
Markov Chains
1.
What is markov chain? Explain with example. [5]
Queuing System
1.
Explain basic characteristics of Queuing System [5]
Random Numbers
1.
Define and develop a Poker test for four-digit random numbers. A sequence of 1,000 random numbers, each of four digits has been generated. The analysis of the numbers reveals that in 525 numbers all four digits are different, 419 contain exactly one pair of like digits, 47 contain two pairs, 9 have three digits of a kind and 7 contain all like digits. Use Poker test to determine whether these numbers are independent. (Critical value of chi-square for a = 0.05 and N = 4 is 9.49). [10]
2.
Generate ten 3 digit random integers and corresponding random variables using Multiplicative Congruential method where a =7, and X0= 22. [5]
3.
Write short notes: a. Hypothesis testing b. Stationary poisson process [5]
Simulation of Computer Systems
1.
Why accuracy of analog computer is low? Explain analog computer with suitable example. Differentiate between analog and digital computer. [10]
Simulation of Continuous and Discrete System
1.
What is transaction in GPSS? Explain about facility in GPSS. Customers arrive at Joey Barbershop one every 15±3 minutes and it takes Joey 18±2 minutes to cut hair of a customer. Create a GPSS model with block diagram for the Barbershop using the concept of facility and run the simulation for 9 hours. [10]
2.
Differentiate between discrete and continuous system. [5]
Verification and Validation
1.
"Building a model right" and "Building a right model". Are both statements same? Discuss the importance of V&V. [5]
