Additional Shifts
Autonomous Maintenance is applied to identify 2 types of deterioration, Natural Deterioration & Forced Deterioration. From the list below, select the reason that DO NOT contribute to Forced Deterioration :
Design Weakness
Corrosion
Environment
Failure to maintain basic conditions
Conditions of use not needed
Choose the best sentence to define changeover time?
The time from running the last product to the time of running the current product
The time between the machine was functional to the time the machine breakdown
The time from running qualified product at the standard rate of the last batch to running qualified product at the standard rate of the next batch
The time from running the machine when operation start to the time when the machine is switched off upon completion of the operation
The time between startup of the operation until the time the operations ends for the day
Which of the following are Tools used for improving the changeover process?

OEE
Optimize internal & external activities
From the list below, select 2 benefits of implementing Quick Change Over (QCO)?
Increases production time
Improves 5S
Detects abnormality
Increases flexibility
Improves safety
Which of the following is NOT a benefit from improving OEE?
Greater system availability
Reduced cycle time
Reduced number of workers
Reduced cost of operation
Reduced inventories
Machine Availability = 99%
Machine Performance = 98%
Quality = 95%
Operation Cost = 92%
RFT = 99%
Calculate the OEE for the above operation :
92%
85%
89%
96%
86%
OEE is a method to measure the efficiency of the equipment in an operation. From the below, select a situation where OEE is not recommended :
OEE is a tool to analyze, and improve your production process
OEE measures inefficiencies and groups them to aid with analyzing the machine
OEE data focuses on factors that adversely affect the value of a machine.
The OEE rate is the maximum potential which a machine can produce set in proportion to the actual value-added time
OEE should be measured on a brand-new equipment to determine the return of investment on this equipment
Select from list below the missing step in Reliability Based Maintenance implementation process according to the order showed above :
Autonomous Maintenance
Improves 5S
Define Asset Criticality
Measure OEE
Improves Quality

Corrective, Preventive, Predictive
Preventive, Predictive, Corrective
Predictive, Preventive, Corrective
Corrective, Predictive, Preventive
Correction, Prevention, Prediction
Which of the following defines Risk?
Risk equals the result of the consequence multiplied by the probability the event will occur
Risk equals the result of the availability multiplied by the probability the event will occur
Risk equals the result of the occurrence multiplied by the probability the event will occur
Risk equals the result of the consequence multiplied by the accuracy the event will occur
Risk equals the result of the consequence multiplied by the repeatability the event will occur
