GMS 401 Lecture 3
Maintenance and Reliability
Outline:
Strategic Importance of Maintenance and Reliability
o Definitions (Maintenance, Reliability, Failure)
o Important Tactics
o Maintenance and Reliability Management
System Reliability
o System with Series Components
o System with Parallel Components (i.e., Providing Redundancy)
o System with Combination of Series and Parallel Components
System/ Product Failure Rate
Strategic Importance of Maintenance and Reliability
Objective of Maintenance and Reliability: To maintain the capability of the
system
System should be designed and maintained to reach expected performance
and quality standards
Good maintenance removes variability (i.e, variability corrupts processes
and creates wastes)
Strategic Importance of Maintenance and Reliability
Maintenance: All ativities ivolved i keepig a syste’s euipet i
working order.
Reliability: The probability that a machine, part, product or system will
function properly for a specified time under stated condition
Failure: Situation in which a machine, part, product or system does not
perform its function.
Potential far-reaching implications of a system failure:
o Operation
o Reputation
o Profitability
o Dissatisfied customers
o Idle employees
o Profits becoming losses
o Reduced value of
investment in plant and
equipment

Other potential disastrous consequence of system failure
o Safety hazard
o Possibly damaging the environment
o Causing injury or death employees
o Causing injury or death to customers, or surrounding residence
Important Tactics
o Maintenance
Implementing or improving Preventive Maintenance
Increasing repair capability or speed
o Reliability
Improving individual components
Providing redundancy
Maintenance and Reliability Management
o Employee Involvement
Partnering with Maintenance Staff
Skill Training
Reward System
Employee Empowerment
o Maintenance and Reliability Procedures
Clean and Lubricate
Monitor and Adjust
Make Minor Repair(s)
Keep Computerized Records
o Results
Reduced Inventory
Improved Quality
Improved Capacity
Reputation for Quality
Continuous Improvement
Reduced Variability
At a glance: Reliability improvements can be made through the use of
proper preventive maintenance
At a glance: Reliability of equipment-> Removes variability of systems->
Customers can reply on products and services to be carried out to
specifications and on time

Reliability
A product or system may be composed of some individual interrelated
components
o Each component performs specific job/ function
o Components may be linked in a Series format
o Components may be linked to a Parallel format
o Components may be linked in a combination of Series and Parallel
formats
System with Series Components
o Overall system reliability is a function of number of components
o Failing one components may result in overall system failure
o If number of components increases, Reliability of the whole system
declines.

OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!
