Reliability centered maintenance

What is the purpose of Reliability Centered Maintenance (RCM)?

To reduce maintenance costs

To improve safety and reliability

To increase production output

To extend equipment life

What is the first step in an RCM process?

Identify failure modes

Establish objectives

Develop preventive maintenance tasks

Analyze system functions

What are the three main categories of failure modes?

Wear, corrosion, and fatigue

Design, installation, and operation

Unscheduled, scheduled, and preventative

Random, wear-out, and overload

Which type of failure mode is caused by a gradual deterioration over time?

Wear-out

Overload

Installation

Corrosion

What is the goal of RCM analysis?

To identify all possible failure modes

To determine the most cost effective maintenance strategy

To maximize equipment availability

All of the above

What is the difference between corrective and preventive maintenance?

Corrective maintenance repairs existing damage while preventive maintenance prevents future damage

Corrective maintenance is proactive while preventive maintenance is reactive

Corrective maintenance is more expensive than preventive maintenance

Preventive maintenance requires less skill than corrective maintenance

What is the primary focus of RCM?

Cost reduction

Safety improvement

Equipment optimization

Production efficiency

What is the definition of �failure� in the context of RCM?

Any deviation from normal performance

A breakdown or malfunction

An inability to meet customer requirements

Any of the above

What is the purpose of FMECA?

To identify potential failure modes

To prioritize maintenance tasks

To analyze risk associated with each failure mode

To develop preventive maintenance tasks

What is the difference between a criticality assessment and a risk assessment?

Criticality assesses the impact of a failure while risk assesses the likelihood of a failure

Risk assesses the impact of a failure while criticality assesses the likelihood of a failure

Criticality assesses the severity of a failure while risk assesses the probability of a failure

Risk assesses the severity of a failure while criticality assesses the probability of a failure

What is the purpose of a Failure Modes Effects Analysis (FMEA)?

To identify potential failure modes

To prioritize maintenance tasks

To analyze risk associated with each failure mode

To develop preventive maintenance tasks

What is the difference between a planned maintenance task and an unplanned maintenance task?

Planned maintenance tasks are scheduled in advance while unplanned maintenance tasks are performed on an as-needed basis

Unplanned maintenance tasks are more costly than planned maintenance tasks

Planned maintenance tasks require more skill than unplanned maintenance tasks

Unplanned maintenance tasks are more complex than planned maintenance tasks

What is the purpose of a Root Cause Analysis (RCA)?

To identify the underlying cause of a problem

To prioritize maintenance tasks

To analyze risk associated with each failure mode

To develop preventive maintenance tasks

What is the difference between a single point failure and a multiple point failure?

A single point failure occurs when one component fails while a multiple point failure occurs when two or more components fail simultaneously

Single point failures are more difficult to diagnose than multiple point failures

Multiple point failures are more costly than single point failures

Single point failures are more likely to occur than multiple point failures

What is the purpose of a Fault Tree Analysis (FTA)?

To identify potential failure modes

To prioritize maintenance tasks

To analyze risk associated with each failure mode

To develop preventive maintenance tasks

What is the difference between a corrective action and a preventive action?

Corrective actions address existing problems while preventive actions prevent future problems

Corrective actions are more costly than preventive actions

Preventive actions require more skill than corrective actions

Corrective actions are more complex than preventive actions

What is the purpose of a Life Cycle Cost Analysis (LCCA)?

To identify potential failure modes

To prioritize maintenance tasks

To analyze risk associated with each failure mode

To evaluate the total cost of ownership for an asset over its lifetime

What is the difference between a condition based maintenance approach and a time based maintenance approach?

Condition based maintenance focuses on monitoring equipment conditions while time based maintenance focuses on scheduling maintenance tasks at predetermined intervals

Time based maintenance is more cost effective than condition based maintenance

Condition based maintenance requires more skill than time based maintenance

Time based maintenance is more reliable than condition based maintenance

What is the purpose of a Reliability Block Diagram (RBD)?

To identify potential failure modes

To prioritize maintenance tasks

To analyze risk associated with each failure mode

To graphically represent the interdependencies between components within a system

What is the difference between predictive maintenance and preventive maintenance?

Predictive maintenance uses data to anticipate and prevent failures while preventive maintenance relies on scheduled tasks to maintain equipment

Predictive maintenance is more expensive than preventive maintenance

Preventive maintenance requires more skill than predictive maintenance

Predictive maintenance is more reliable than preventive maintenance
