Chapter 17: Maintenance & Reliability

Question 1

Maintenance and Reliability (Goal)

Answer 1

maintain the capability of the system

Good maintenance and reliability management enhances a​ firm’s performance and protects its investment.

Question 2

Reliability tactic

Answer 2

improving individual components

Question 3

Maintenance tactic

Answer 3

increasing repair speed & capabilities

implementing preventive maintenance

Question 4

Reliability

Answer 4

Reliability is the probability that a machine part or product will function properly for a specified time under stated conditions.

To compute the reliability of a​ system, we assume that the reliability of an individual component does not depend on the reliability of other components.

To increase the reliability of a​ system, redundancy can be added in the form of backup components or parallel paths.

As the number of components in a series​ increase, the reliability of the whole system declines

If any one component fails to​ perform, the whole system does not fail

Question 5

Maintenance

Answer 5

Maintenance includes all activities involved in keeping a​ system’s equipment in working order

he appropriate maintenance policy is developed by balancing preventive maintenance costs and breakdown maintenance costs. The problem is that
full breakdown costs are seldom considered.

Question 6

Redundancy

Answer 6

the use of backup components or parallel paths to raise​ reliability

Question 7

MTBF

Answer 7

the expected time between a repair and the next failure of a​ component, machine,​ process, or​ product

Question 8

Autonomous Maintenance

Answer 8

operators partnering with maintenance personnel to​ observe, check,​ adjust, clean, and​ notify

Question 9

Infant mortality

Answer 9

is the failure rate early in the life of a product or process and is usually due to improper use.

Question 10

Preventive maintenance

Answer 10

The process that is intended to find potential failures and make changes or repairs

Question 11

Productive maintenance

Answer 11

Emphasizing total cost of ownership when purchasing machines (include service and maintenance)
Designing machines that are​ reliable, easy to​ operate, and easy to maintain.
Training workers to maintain their own machines

Question 12

Total Productive Maintenance (TPM)

Answer 12

combines total quality management with a strategic view of maintenance from process and equipment design to preventive​ maintenance
