What does MTBF stand for in reliability metrics?
Mean Time Between Fixes
Mean Time Before Failure
Mean Time Between Failures
Mean Time Between Faults
MTBF stands for Mean Time Between Failures, representing the average time between system breakdowns. It is a fundamental reliability metric used to assess equipment performance.
Which maintenance metric measures the average time required to restore equipment after a failure?
Mean Time To Failure (MTTF)
Mean Time To Operate (MTTO)
Mean Response Time (MRT)
Mean Time To Repair (MTTR)
MTTR stands for Mean Time To Repair and indicates the average time required to restore failed equipment. It is critical for understanding maintenance efficiency and downtime impact.
What is the primary goal of preventive maintenance?
Maximize production speed
Reduce unplanned downtime
Increase equipment replacement
Eliminate all maintenance costs
Preventive maintenance aims to reduce unplanned downtime by scheduling inspections and servicing before failures occur. This proactive approach keeps equipment running reliably.
In maintenance documentation, what does CMMS stand for?
Certified Maintenance Management Service
Computerized Maintenance Management System
Central Machinery Monitoring System
Comprehensive Maintenance Methodology Software
CMMS stands for Computerized Maintenance Management System, which is software used to plan, track, and optimize maintenance activities and records. It centralizes maintenance data for better decision-making.
Which safety procedure ensures equipment is fully de-energized before maintenance?
Safety Audit
Hot Work Permit
Lockout/Tagout
Personal Protective Equipment
Lockout/Tagout procedures ensure that equipment is isolated from energy sources and cannot be accidentally started. This is critical for worker safety during maintenance tasks.
How is equipment availability calculated using MTBF and MTTR?
(MTBF + MTTR) / MTTR
MTBF - MTTR
MTBF / (MTBF + MTTR)
MTTR / (MTBF + MTTR)
Availability is calculated as MTBF divided by the sum of MTBF and MTTR. This ratio expresses the proportion of time a system is operational.
Which curve describes the typical failure rate over the life cycle of equipment?
S-curve
Gaussian distribution
Bath-tub curve
Exponential decay curve
The bathtub curve illustrates three failure phases: early failures, constant random failures, and wear-out failures. It is a standard model for equipment life-cycle behavior.
What does FMEA stand for in reliability improvement techniques?
functional Maintenance and Evaluation Analysis
Failure Monitoring and Equipment Audit
Failure Mode and Effects Analysis
Fault Mapping and Evaluation Approach
FMEA stands for Failure Mode and Effects Analysis and is used to identify potential failure modes and their impacts. It helps prioritize corrective actions to improve reliability.
Which root cause analysis technique uses iterative questioning to drill down to the root cause?
Fault Tree Analysis
Pareto Analysis
Fishbone Diagram
5 Whys
The 5 Whys technique involves asking 'why' multiple times to peel away layers of symptoms and reach the underlying cause. It is simple yet effective for root cause analysis.
In FMEA, the Risk Priority Number (RPN) is the product of which three factors?
Cost à - Time à - Complexity
Severity à - Occurrence à - Detection
Severity à - Frequency à - Cost
Probability à - Impact à - Prevention
RPN is calculated by multiplying severity, occurrence, and detection ratings in FMEA. It quantifies the risk level to help prioritize mitigation efforts.
What reliability improvement technique involves adding duplicate components to prevent single points of failure?
Corrective Maintenance
Predictive Maintenance
Total Productive Maintenance
Redundancy
Redundancy improves reliability by providing backup components that take over when one fails. This approach eliminates single points of failure.
Which predictive maintenance method uses vibration analysis to detect bearing faults?
Thermography
Vibration Analysis
Oil Analysis
Ultrasonic Testing
Vibration analysis monitors machinery vibration signatures to detect imbalances or bearing defects before they cause failure. It is a common predictive maintenance technique.
What is a key feature of Total Productive Maintenance (TPM)?
Outsourcing all maintenance tasks
Eliminating preventive maintenance
Operator involvement in routine maintenance
Only performing corrective repairs
TPM emphasizes empowering operators to perform basic maintenance tasks and inspections. This increases equipment ownership and overall reliability.
Which inventory categorization method prioritizes spare parts based on usage value?
ABC Analysis
Pareto Analysis
XYZ Analysis
Criticality Matrix
ABC Analysis classifies inventory into categories A, B, and C based on usage value, focusing control efforts on the most valuable parts. It helps optimize spare parts management.
Which document typically records the details of completed maintenance activities for future analysis?
Safety audit report
Work order log
Equipment specification sheet
Preventive checklist
A work order log records each maintenance job, including details like date, actions taken, and parts used. This history supports trend analysis and continuous improvement.
If MTBF is 100 hours and MTTR is 10 hours, what is the system availability?
10%
91.1%
90.9%
100%
Availability = MTBF / (MTBF + MTTR). Substituting 100 / (100 + 10) yields 0.909 or 90.9% availability.
What is the primary difference between preventive and predictive maintenance?
Preventive maintenance requires more advanced sensors
Predictive maintenance is cheaper in all cases
Preventive maintenance only occurs after failure
Predictive maintenance uses real-time condition monitoring
Predictive maintenance relies on condition monitoring data to schedule service exactly when needed. Preventive maintenance follows fixed schedules regardless of actual equipment condition.
In Reliability-Centered Maintenance (RCM), which analysis step focuses on identifying functions and functional failures of an asset?
Preventive Task Selection
Maintenance Strategy Review
functions and functional Failures analysis
Failure Modes and Effects Analysis
The functions and functional Failures step in RCM defines what an asset is supposed to do and how it can fail to fulfill that function. This is foundational for subsequent failure analysis.
For a system requiring 99.9% uptime, what is the maximum allowable downtime per year (in hours)?
876 hours
8.76 hours
87.6 hours
0.876 hours
99.9% uptime allows 0.1% downtime. Over 8,760 hours in a year, 0.1% equals 8.76 hours of allowable downtime.
Which best practice helps maintain documentation integrity in maintenance management?
Using handwritten notes only
Archiving documents in an unsecured folder
Implementing version control and access restrictions
Allowing unrestricted edits by all staff
Version control and controlled access ensure that documentation remains accurate and tamper-proof. This maintains reliable records for compliance and analysis.
