Document Summary

Reliability: the ability of a product or part to perform its intended funcion under a prescribed set of condiions. Applicaion: product design, producion system design. Reliability of a product or part is used in two ways: reliability when acivated, reliability for a given length of ime. Reliability management involves establishing, achieving and maintaining reliability objecives for products. Increase overall reliability: overdesign: enhance design to avoid failure. For example, use more durable material: design simpliicaion: reduce number of components, use redundancy in the design: by providing backup components. Reliability for a given length of ime: this approach usually considers ime dimension, designing services that includes imes dimension, measurement of reliability, failure rate per hour, mean time to failure (mttf) The average length of ime before failure of a product or component: probability of failure before a speciic ime, availability. The probability that the item put into service at ime 0 will fail before some speciic ime, t.
