SCHOOL OF SCIENCE AND TECHNOLOGY

MARCH/APRIL 2014 EXAMINATION

COURSE CODE: CIT 412

COURSE TITLE: MODELLING & SIMULATION

TIME ALLOWED: 2 HOURS

INSTRUCTION:ANSWER ANY FOUR QUESTIONS OUT OF SIX

1. (a) Explain the following terms:

i. Modelling

ii. Model

iii. Simulation

(b) Enumerate and explain five types of Models available, outlining at least five procedures involved in

modelling.

2. (a) Explain how a computer generates a sequence of random numbers, outlining other ways of

Generating pseudo-random numbers.

(b) Write a QBASIC program to simulate the tossing of a fair coin 10 times. The program displays a H

when a Head appears and a T when a Tail appears.

3. (a) Briefly explain theCongruential Methods. Using the Congruential method, generateat least eight

sets of random numbers, where m = 8, a = 5, c = 7 and the Seed Xo = 4.

(b) Enumerate and discuss explicitly the various methods of generating random numbers; indicating the

formulas applicable under each methods.

4. (a) Using suitable diagram, explain the term Visual Modelling.

(b) Enumerate and explain five types of Models available, outlining at least five procedures involved in

modelling.

5. (a) Suppose the output of the program of example 3 is: HHTHHTTTHH and that there are two

players X and Y involved in the tossing of the coin. Given that player X wins N50.00 from

player Y if a head appears and loses it to player Y if a tail appears. Determine who won the

game and by how much.

(b) Outline and discuss the three perspective to a Data Model

6. (a) Explain the term Simulation and enumerate its objectives and its various types.

(b) Using suitable diagram, explain the various steps involved in the physical simulation process.
