CMRP Exam - Questions & Verified AnswersReplacement Asset Value (RAV) ✔️Ans - defined as the cost that would be
incurred, in today's dollars, to replace the facility and equipment in its current
configuration.
Overall Equipment Effectiveness (OEE) ✔️Ans - metric for measuring how
well a process is operating by evaluating the three major process components:
availability, performance efficiency (rate/speed) and quality. The process can
be a single piece of equipment, a manufacturing cell, a production line or a
plant
Overall Equipment Effectiveness (OEE) ✔️Ans - Availability × Performance
Efficiency × Quality
Availability ✔️Ans - defined as the percentage of time that the process is
actually operating (uptime) compared to when it is scheduled to operate
Performance efficiency (rate/speed) ✔️Ans - defined as the percentage of
Actual Run Rate/Cycle Time to the Best Run Rate/Cycle Time
Quality ✔️Ans - defined as the percentage of "First Pass, First Time"
Saleable Production to the Actual Production
Actual Production ✔️Ans - total quantity of production produced in the
given time period, regardless of its quality
Lagging Indicator ✔️Ans - An indicator that measures performance after
the business or process result starts to follow a particular pattern or trend
Leading Indicator ✔️Ans - An indicator that measures performance before
the business or process result starts to follow a particular pattern or trend
Three (3) sets of measurable components that make up the maintenance and
reliability process ✔️Ans - 1. Management processes and behaviors
(mission and vision, people skills)
2. Operational execution (operations, design and maintenance)
3. Manufacturing performance (availability, quality, cost and benefits)
, mean metrics ✔️Ans - metrics that describe the Reliability, Availability and
Maintainability (RAM) characteristics of a component, asset or even facility
Inherent Availability ✔️Ans - measure of the variables inherent in the
design that affect availability. In the calculation of downtime, it usually
includes only active repair time. It does not include preventive maintenance
time and administrative or logistic delays, but does include corrective
maintenance downtime
Inherent Availability Formula ✔️Ans - Ai = MTBF / (MTBF + MTTR)
Where MTBF = Mean Time Between Failures
And MTTR = Mean Time to Repair (corrective maintenance only)
Achieved Availability ✔️Ans - probability that an item, when used under
design conditions in an ideal support environment, will perform satisfactorily.
It includes both active repair time and preventive maintenance time, but
excludes administrative and logistic delay times
Achieved Availability Formula ✔️Ans - Aa = MTBM / (MTBM + MDTM)
Where MTBM = Mean Time Between Maintenance
And MDTM = Mean Downtime for Maintenance
Operational Availability ✔️Ans - probability that an item, when used under
design conditions in an operational environment, will perform satisfactorily. It
includes active repair time, preventive maintenance time and administrative
and logistic delays and represents the availability that is actually experienced
Operational Availability Formula ✔️Ans - Ao = MTBM / (MTBM + MDT)
Where MTBM = Mean Time Between Maintenance
And MDT = Mean Down Time
Equipment Availability ✔️Ans - defined by The Association for
Manufacturing Technology as the percentage of potential production time
during which equipment is operable. The term is applied to a single piece of
manufacturing equipment (or several machines acting as a unit)
Equipment Availability Formula ✔️Ans - = [Production Time / Potential
Production Time] x 100
