For a machine to be a good candidate for preventive maintenance
A) the consequences of failure must exceed the cost of preventive maintenance and the MTBF distribution must have a large standard deviation.
B) the consequences of failure must exceed the cost of preventive maintenance and the MTBF must be relatively low.
C) the consequences of failure must exceed the cost of preventive maintenance and the MTBF distribution must have a relatively low standard deviation.
D) the consequences of failure must exceed the cost of preventive maintenance and the MTBF must be relatively high.
E) the consequences of failure must be relatively unknown and, therefore, risky.
Preventive Maintenance
Scheduled maintenance activities carried out on equipment to prevent unexpected failures or malfunctions.
MTBF Distribution
Statistical representation of the Mean Time Between Failures, indicating the reliability and performance of a system.

Final Answer :
C
Explanation :
For a machine to be a good candidate for preventive maintenance, it's crucial that the consequences of its failure are more costly than the maintenance itself, and that the Mean Time Between Failures (MTBF) distribution is predictable, which is indicated by a relatively low standard deviation. This predictability allows for effective scheduling of maintenance to prevent failures.
