Acceptance sampling plans based on truncated life tests for Rama distribution

International Journal of Quality & Reliability Management, 2019
PurposeLifetime data are used in many different applied sciences, like biomedicine, engineering, insurance and finance and others. The purpose of this paper is to develop a new acceptance sampling plans for Rama distribution when the mean lifetime test is truncated at a pre-determined time. The minimum sample sizes required to assert the specified life

Attribute control charts for the Dagum distribution under truncated life tests

Life Cycle Reliability and Safety Engineering, 2019
In this paper, an attribute control chart for lifetime of the product follows Dagum distribution under number of failures before a specified time period is proposed. The sensitivity of the proposed chart is studied using the average run length (ARL).

Acceptance Sampling from Truncated Life Tests

2019
Acceptance sampling approach is helpful in reducing the cost and time of the inspection of a submitted product. In this modern era, the reliability of the products is very high. The experimenters may wait a long time to record the required numbers of failures.

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 ...

Attribute Control Charts for the Weibull Distribution under Truncated Life Tests

Quality Engineering, 2015
ABSTRACTIn this article, an attribute control chart is proposed when the lifetime of a product follows a Weibull distribution, which is based on the number of failures from a truncated life test. The coefficients of the proposed control chart and the test duration are determined so that the average run length when the process is in control is close to ...

Acceptance sampling plan based on truncated life tests for exponentiated fréchet distribution

Journal of Statistics and Management Systems, 2013
Abstract In this paper, exponentiated Frechet distribution is considered as a model for a life time random variable when the life test is truncated at a pre-assigned time. The operating characteristic functions values of the suggested sampling plans and the corresponding producer's risk are obtained.
