Question
what is the difference between corrective maintenance and predictive maintenance?
a corrective maintenance refers to routine checks and cleaning of equipment to prevent breakdowns, whereas predictive maintenance refers to replacing parts after a failure has occurred.
b corrective maintenance refers to performing maintenance only after equipment has broken down, whereas predictive maintenance refers to scheduling repairs based on regular intervals regardless of equipment condition.
c corrective maintenance refers to regular inspections to identify potential problems,
First, recall the definitions: Corrective maintenance is done after a failure (to correct the issue), and predictive maintenance uses data/monitoring to predict and schedule repairs before failure. Let's analyze options:
- Option A swaps the definitions (corrective should be after failure, predictive is proactive, not routine checks for predictive).
- Option B: Corrective is after breakdown (correct), but predictive is not "based on regular intervals regardless of condition" (that's preventive, not predictive). Wait, maybe there's a typo, but among given, let's re - check. Wait, maybe the user's option C is cut off, but from A and B:
Wait, actually, the correct understanding: Corrective maintenance is reactive (done after equipment fails), Predictive maintenance is proactive (using data to predict when maintenance is needed, like condition - based). Let's re - evaluate:
Option B: "Corrective maintenance refers to performing maintenance only after equipment has broken down" (correct for corrective). "Predictive maintenance refers to scheduling repairs based on regular intervals regardless of equipment condition" – no, that's preventive maintenance (time - based, regardless of condition). But maybe in the options, this is the best available? Wait, maybe the original question's option C is incomplete, but from A and B:
Option A is wrong (swaps corrective and predictive). Option B: corrective part is correct (after breakdown), predictive part – maybe a misstatement, but among the two, B's corrective definition is correct, and maybe the predictive part has a typo (maybe "based on equipment condition" instead of "regular intervals"). But given the options, let's check again.
Wait, maybe I made a mistake. Let's re - define:
Corrective Maintenance: Fixes equipment after it has failed (reactive).
Predictive Maintenance: Uses condition monitoring (sensors, data) to predict when maintenance is needed (proactive, before failure).
Preventive Maintenance: Scheduled at regular intervals (time - based, regardless of condition, to prevent failure).
So in option B, the predictive part is misdefined (says regular intervals, which is preventive), but option A's definitions are swapped (corrective is said to be routine checks - no, routine checks are preventive; predictive is said to be after failure - no, that's corrective). So between A and B, B's corrective definition is correct, and maybe the predictive part is a mistake, but it's the better option among the two. Wait, maybe the user's option C is correct, but since it's cut off, but from the given, let's assume.
Wait, perhaps the intended correct option is B? Wait, no, maybe I messed up. Wait, let's start over.
Correct definitions:
- Corrective Maintenance: Maintenance performed to restore equipment to a functional state after a failure has occurred.
- Predictive Maintenance: Maintenance performed based on the actual condition of the equipment (using monitoring, sensors, data analysis) to predict when maintenance is needed, so it's done before failure.
Now, option A:
"Corrective maintenance refers to routine checks and cleaning of equipment to prevent breakdowns" – no, routine checks to prevent are preventive. "Predictive maintenance refers to replacing parts after a failure has occurred" – no, that's corrective. So A is wrong.
Option B:
"Corrective maintenance refers to performing maintenance only after equipment has broken down" – correct (reactive). "Predictive maintenance refers to scheduling repairs based on regular intervals regardless of equipment condition" – no, that's preve…

B. Corrective maintenance refers to performing maintenance only after equipment has broken down, whereas predictive maintenance refers to scheduling repairs based on regular intervals regardless of equipment condition.
