Document Summary

Reliability: the ability of a product, part, or system to perform its intended function under a prescribed set of conditions. In effect, reliability is a probability: failure rate= 1-percent probability of functioning as intended, reliability of a product or part is used in two ways. Reliability when activated: focuses on one point in time and is often used when a product or part must operate for one time, such as a missile or an air bag in a car. Reliability for a given length of time: focuses on the length of service, such as most other products e. g. , a car: reliability is an important dimension of product quality. Determining that probability when the product consists of a number of independent components requires the use of rules of probability for independent events. Independent events have no relation to the occurrence or nonoccurrence of each other.
