BICEE-020 RELIABILITY AND OPTIMIZATION OF STRUCTURES
Time hours Maximum Marks: 70
Note: Attempt any ten questions. All questions carry equal marks. Use of scientific calculator is permitted.
1. A concrete mixer machine contains a component that is vital to its operation. The reliability of component is 80%. To improve the reliability of a machine, a similar component is used in parallel to form a system. The concrete mixer machine will work provided that one of these components functions correctly. Calculate the reliability of the machine. 7
2. A problem of structural design is given to three students B and C whose chances of solving it are 1/3 and respectively. What is the probability that the problem will be solved? 7
3. In a bolt factory, machines B and C manufacture 35% and 40% of the total output, respectively. Of their outputs, and are defective bolts. A bolt is chosen at random and found to be defective. What will be the probability that the bolt came from machine A,B or 7
4. If 20% of the bolts produced by a machine are defective, determine the probability that out of 4 bolts chosen at random and at most 2 bolts, will be defective. 7
5. Describe any two methods of computing structural reliability. 7
6. Find the coefficient of correlation for the following values of x and y 7
x Y
1 2
2 5
3 3
4 8
5 7
7. The guidance system of a ship is controlled by a computer that has three major modules. In order for the computer to function properly, all three modules must function. Two of the modules have reliabilities of 0.95 and the other has a reliability of 0.99. What is the reliability of the computer? A backup computer identical to the one being used will be installed to improve the overall reliability. Assuming the new computer automatically functions. if the main one fails, determine the resulting reliability. 7
8. Explain Monte Carlo methods and give the situation where these methods are useful. 7
9. Explain design variables and design constraints in respect of optimization problem with suitable examples. 7
10. Solve the following linear programming problem using graphical method: 7
Minimize z =20x1 10x2
subject to x1 2x2 40
3x1 x2 30
4x1 3x2 60
x1, x2
11. Solve by Simplex method the following linear programming problem:
Minimize z=x1-3x2 3x3
subject to 3x1-x2 2x3 7
2x1 4x2 -12
-4x1 3x2 8x3 10
x1,x2,x3 >=0.
12. Explain unimodal functions with suitable examples. Also discuss in brief the Quasi-Newton method.
