Document Summary

Companies such as walt disney or frito-lay know the importance of good maintenance because lack thereof can result in dollars and time lost. There is an interdependence between operators, machines, and mechanic.

Reliability is the profitability that a machine part or product will function properly for a specified time under stated conditions. There are four different tactics for improving reliability and maintenance. Systems are composed of a series of individual interrelated components and if one fails the whole system can fail. Improving individual components: understanding occurrence of failures is important. As the number of components in a series increases, the reliability of the whole system declines quickly: to measure reliability in a system is:
