Question

replacement due to sudden failure is studied under

Answer 1

Explanation:

The replacement problems are concerned with the situations that arise when some items such as machines, men, electric appliance etc. need replacement due to their decreased efficiency, failure or breakdown. The deteriorating efficiency or complete breakdown may be either gradual or all of a sudden.

Answer 2

Answer:

Replacement due to sudden failure is studied under a simple probabilistic model. Many electronic items such as resistors, tube lights, transistors bulbs, can typically fail all of a sudden, instead of gradual deterioration. The apparent failure of the product may typically result in a complete system breakdown.
