Document Summary
Reliability: poor maintenance can be disruptive, inconvenient, wasteful and expensive in dollars and lives, the objective of maintenance and reliability is to maintain the capability of the system to remove variability. Maintenance: the activities involved in keeping a system"s equipment in working order. Reliability: the probability that a machine part or product will function properly for a speci ed time under stated conditions. Implementing or improving preventive maintenance increasing repair capabilities or speed. Improving individual components: systems are composed of a series of individual interrelated components, as the number of components in a series increases, the reliability of the whole system declines very quickly, we compute reliabilities as . Product failure rate (fr): basic unit of measure for reliability. Fr(%) = number of failures number of units tested. Fr (n) = number of failures number of unit-hours of operation time.
