Acceptance sampling based on truncated life tests for generalized Rayleigh distribution

Journal of Applied Statistics, 2006
This paper considers the problem of an acceptance sampling plan for a truncated life test when the lifetime follows the generalized Rayleigh distribution. For different acceptance numbers, confidence levels, and values of the ratio of the fixed experiment time to the specified mean life, the minimum sample sizes necessary to ensure the specified mean ...

Acceptance Sampling Plans for Half-Normal Distribution Under Truncated Life Tests

American Journal of Mathematical and Management Sciences, 2013
SYNOPTIC ABSTRACT In this work, we study acceptance sampling plans for half-normal distribution when the lifetime experiment is truncated at a preassigned time. For various acceptance numbers, confidence levels, and values of the ratio of the experimental time to the specified average life, we obtain the minimum sample size required to ensure a certain

Modified Sequential Probability Ratio Test Based on Truncated Life Tests on the Exponential Distribution Functions

Journal of Physical Mathematics & its Applications, 2023
Modified Sequential probability ratio test (MSPRT) technique helps to increase the reliability and speed of stabilization detection on the Non homogenous poison process (NHPP) with the maximum number of software faults to reduce error between the consumer risk and producer risk, with the time cumulative system of hours.

Developed acceptance sampling plans for the Shanker distribution based on truncated life tests

International journal of neutrosophic science
This paper introduces new acceptance sampling plans for situations where the life test is terminated at a predetermined time. The minimum sample sizes needed to guarantee a specified average lifetime are determined for different acceptance numbers ...

Monitoring number of non-conforming items based on multiple dependent state repetitive sampling under truncated life tests

Communications in Statistics - Theory and Methods, 2020
In this study, an attribute np control chart based on multiple dependent state repetitive sampling is proposed for monitoring the lifetime of the products since the lifetime of the products is considered as an important quality characteristic of many ...

Acceptance sampling plan for truncated life test having generalized Pareto distribution

Life Cycle Reliability and Safety Engineering, 2019
In this study, repetitive acceptance sampling plan for truncated life test is developed for that situations in which the lifetime of the product follows the generalized Pareto distribution. The parameters of the proposed plan such as sample size, acceptance numbers and probability of lot acceptance are determined when the producer’s risk, consumer’s ...

Sequential Sampling Plan in the Truncated Life Test for Weibull Distribution

Journal of Testing and Evaluation, 2018
Abstract The truncated life test is usually applied for reducing experiment time. The lifetime of a product is assumed as its quality characteristic, and the sequential sampling (SS) plan is applied in the context of the truncated life test. In SS, the samples are selected from the lot stage by stage.

ACCEPTANCE SAMPLING PLANS FOR BIRNBAUM-SAUNDERS DISTRIBUTION UNDER TRUNCATED LIFE TESTS

International Journal of Reliability, Quality and Safety Engineering, 2005
For modeling fatigue data, satatistical distributions are often used because the lifetimes of a fatiguing material can vary due to manufacturing variation or random flaws in the material. One of the popular distributions to describe the number of stress cycles until failure, or analogously, time to failure is the Birnbaum-Saunders distribution. If the

Estimation of a Time-Truncated Exponential Parameter Used in Life Testing

Journal of the American Statistical Association, 1977
Abstract This article proves the asymptotic unbiasedness and consistency when the sample size of the maximum likelihood estimate of the mean θ of an exponential distribution in a time-truncated experiment is random. Convergence of to with μ and σ2 independent of x is established.

Acceptance Sampling Plans Under Truncated Life Tests Assuming a Half Exponential Power Life Distribution

Economic Quality Control, 2013
In this paper, we consider acceptance sampling plans assuming a half exponential power life distribution and a life test that is truncated at a preassigned time. For various acceptance numbers, confidence levels and values of the ratio of the true mean lifetime to the specified mean life, we determine the minimum sample size necessary to ensure a ...
