Early Failures in Automobile Parts: A Background Study in Reliability.
ResearchPublished 1964
An examination of one particular aspect of reliability--an intially high failure rate. It has been explored mainly in the field of electronics and has an important bearing on the achievement of maximum reliability for aircraft, missiles, and space vehicles. The early mortality of automobile parts is examined here through the analysis of warranty-claim information from a car manufacturer for 1961. The Weibull probability distribution is fitted to the early claims data to indicate the trend (increasing, decreasing, or constant) in the observed failure rate. Since the data come from a nonrandom sample, a simulation of the claim-generating process is performed to develop the exposure pattern and permit the actuarial determination of the true conditional failure rates for the analysis. 36 pp. Bibliog.
