Question

Consider the following statements with reference to maintenance and service of the product after delivery to the customer : 

1. Reliability analysis uses statistics of failures to estimate, understand and improve the performance of the equipment and its maintenance 

2. Reliability analysis records supports or guides the maintenance engineer in improving the performance of the product under service 

Which of the above statements is/are correct ? 

1. 1 only
2. 2 only
3. Both 1 and 2
4. Neither 1 nor 2

Answer 1

Correct Answer - Option 3 : Both 1 and 2

The ability of a component to work as per the specifications for a particular time interval is called its reliability. Theoretically, it is defined as the probability of success. Reliability analysis is applied at the design stage and helps in maintaining during various failure stages.

The reliability analysis is recorded and the maintenance engineer works out on the basis of statistical data present about the poor performance of equipment and helps him identify the damage zone. This way Reliability analysis records support the maintenance engineer in improving the performance of the product under service.

Hence both the statements are true.
